so this is how to use cad sketcher as it

currently is right now so very much work

in progress to make this thing right

here now it's not super duper

complicated but it's not super duper

simple either and the end result is

pretty clean overall it's definitely 3d

printable so let's go and dive straight

into it starting with a nice fresh new

blender file let me show you how to get

the technical drawing so it's down

linked in the description you can get

the technical drawing and in that

technical drawing you can then just drag

and drop that over into blender you can

use it like this but i don't like using

it like that so i'm going to select it

delete it and then on the top left just

in case you don't know the blender you

are you can drag out a new window change

this over to the image editor and change

here on the drop down next to new to the

image that you just brought in so you

can then look around use the middle

mouse button to move around now i'm not

going to keep this super duper simple

i'm going to think that you know a

little bit of blender i'm just sort of

going to jump

into a little bit of quite a bit

deeper parts of blender i am going to

keep this here on the side just so you

can see exactly where i'm going to be

working with now there are a whole bunch

of shortcuts that i'm going to be using

that are new to cad sketcher and they

are also linked down in the description

so let's jump straight into this with a

new shortcut of ctrl shift a to create a

new sketch i'm going to go here on this

plane right there i'm going to press 1

to look directly at that plane and i'm

going to create myself a rectangle right

there i'm going to right click to cancel

the tool and go back to selection i'm

going to click on the origin point click

on this line here and i'm going to use

the shortcut shift n for midpoint

constraint now i have no idea what size

this really is right this minute so i'm

just going to grab these two bottom

points right here i'm going to press alt

d because all the alt shortcuts are for

dimensioning all the shift shortcuts are

for geometric constraints i'm going to

click into here and i'm going to make

this a hundred and fifty so now i'm

getting a little bit more perspective of

the size of the model there we go now i

gonna have some rounded corners here

unfortunately we don't have the fillet

tool just yet so i'm actually just going

to delete all of these points right here

i'm not going to use them for the time

being what i'm going to do is i'm going

to create a line upwards this way create

a line upwards this way and create a

line along like that i'll press a for

the arc tool then i'll click and then

just create myself two arcs like this

and like this now i technically could

mirror all of this but i just want to

make my life nice and simple i'm going

to right click to cancel that i'm going

to select this select that press shift t

to create a tangent constraint so i'm

going to tangently constrain all of

these to one another so once all of that

has been tangently constrained let's

make these two arcs as well let's make

them equal to another so let's shift e

for equal and now let's actually do a

radius on them as well so select this

here and that would be alt r for radius

or alt d automatically it will do it for

an arc so here the radius that i have

set for this one is 30 so we'll click

into it type in 30 and that is now set i

want to press n to open up my side menu

go to cad sketcher and i want to just

double check my degrees of freedom you

should technically always sort of have

this up because it will let you know

when things are going wrong and i know

what it is it's this top one right here

so i'm just going to move this little

thing down select this point here select

this point here and this is a dimension

so let's go for alt d for the

dimensioning now this is the distance

between those i want this to be the

vertical distance so let's click into

here change the alignment to be the

vertical distance that's more like it

and i want to change this to be 100

brilliant now that we have this set in

place let's add a couple more things i'm

also just going to close this up just a

little bit this way more than i think i

just want to show you that model because

i sort of have this already on to my

side here that i can see it so i'm

wanting to actually create all the

referencing for everything here yes

we're going to be doing a little bit of

referencing so let's create a line i'm

going to go from the origin point all

the way up to here brilliant i'm going

to right click on this and set this to

construction and then i'm also going to

grab myself a circle pro c for the

circle do one circle do another circle

making sure that i'm going from the

center so those are both using this

point right here so i can select that

point select the origin point press alt

d and set the dimension here that i'm

looking for which is 53

okay so we have degrees of freedom which

is these ones obviously right here

so let's grab this circle here alt o for

this one and i'm going to set this

circle right here from the sketch it is

telling me that this is 30 and then

we've got this one here alt o and from

the sketch let me just drag this out so

things a little bit more visible this

one here is going to be

55

so now that those are set we don't want

this outer one actually because that's

not going to really help us in any way

so i'm going to right click it and turn

it into a construction line now i want

to add the holes that we're going to

have here on the side so i'll press c

for circle i'll create a circle here

create another circle here right click

to cancel and go back into my selection

select both of these press shift e for

equal select one of them and then i'm

going to do alt r for radius i'm going

to set the radius of this one to be 18

but that is not what i wanted what i

actually wanted is the diameter so i'll

change it right here so i'll put that

into 18 but that's not what i want i

want to change this toggle right here

and then change that back over to 18

diameter like so

okay so now that i have

that like that what do i have left well

i've got this little top notch that i

want to add some construction mesh for

later so i'm going to add another

rectangle so that is r to bring in a

rectangle like so i'm going to actually

coincident point this one here right

click i'll select these two and i'll

press shift c to do a coincident point

there and there is a degree of freedom

right this minute right here so i'm

going to select the point here that

point there press alt d to do a distance

constraint there and this distance for

this one is 40. now all of this here is

a little bit much i don't need this to

actually be real lines i need to turn

this into all into construction lines so

i'm selecting all of these and turning

it into construction lines now this one

here and it's getting in the way so i

have to right click and get rid of the

visibility so i'm able to turn this one

back into construction line and i'm

going to have to go back into my

entities scroll down and bring on the

visibility okay now there's one more

that will cut out that i want to put in

here now remember all of this is still

very much in development so don't go too

critically on this

um so

turning all of this into construction

there we go construction construction

construction and i'm going to set this

point and that point there with a shift

m for midpoint constraint select these

two points here go alt d for a distance

that should be 10. oh i'm close but not

close enough so that's now 10 here and

lastly i'm pretty sure we only have one

freedom left yep which is this one right

here alt d and we're going to set this

one to 20

and that is this sketch now completely

done so i'm going to change this one i'm

going to call this the back plate

so back

and underscore plate

i'm happy with that i'm going to change

this into mesh when i go out and leave

this like that okay now that i've done

this i'm going to press w for my normal

selection select what i've just created

here go to the modifiers and change this

modifier with a solidify and the

thickness that i'm aiming for is 13.

okay here we have it that is now in

place like so so how am i going to be

creating the rest of this well let's

create the base first so to create the

base first i can't actually do any

referencing of the actual sketch which

is a little bit of a shame so what i'm

going to do is just create another

sketch and i'm going to go from the top

down and i'm just going to start

building exactly what we just did but

once again so with that like that i knew

be able to see the origin point and i

don't want this mesh in the way so i'm

just going to click over here and turn

off the mesh right there brilliant i'm

then going to select these two press

shift m you already know what i'm about

to do here so let's just go with it

these two here we're going to do a

distance constraint set that to 150. now

these here are technically not really

what we're needing because we have some

lovely

arcs and all the rest so this time i'm

going to start with the arcs

and let's go for an arc here and an arc

there press l for the line we're going

to go from line to line another line

over here and yet another line this way

let's turn this one into a vertical line

so shift v and then make all of these

tangent to one another so remember that

is shift t

to the tangent constraint

so with all of these now tangent to one

another let's also make these two equal

to one another so shift e and then

lastly we have this degree of freedom as

well as the radius of this so i'm just

going to select one of these go shift r

and click on this radius oh it's not

letting me i'm going to do

alt o and that's going to let me do that

one because it's not a radius that i'm

wanting here and so i've got to change

this

over to

30 i'm pretty sure but it is a radius of

30. so change this here to a radius

here

of 30.

there we go radius of 30 that is now set

in place that's all looking good to me

we do have one degree of freedom left

which is this one right here alt d

change that again to a vertical and

we're going to change this one this time

to be

80. brilliant

so now let's do the holes that we need

to do so grab one there and another one

here

make those two equal to one another and

let's also set this with an alt o

and these are going to be 18

so that should be everything in place it

is a fully defined sketch i'm going to

call this one the base plate

um

base plate

because the other one is the back plate

and the plaque plate

awesome and make sure that this is

converting it over to mesh leave it this

way then i'll press w select this one

once again

add a solidify modifier we're going to

go up by that number of 13 once again

this time in one make sure that it's an

even thickness just in case this one

even thickness as well so there we go

we're coming together coming together

now this back plate i want to be able to

see this sketch so i'm going to turn

this on as i can see that sketch and

we're going to be sketching on the same

plane once again we're actually going to

be able to use

the

mesh the whatever is that sketch the

magic things that are

card sketcher to sort of

reference it that's right there's

technically already referencing so let's

add a sketch once again on the same

plane and this time i'm going to turn

off the mesh and

we're going to have our sketch left here

i'm do a circle i'm just going to click

here and click it out click here and

click it out and i want these two to be

equal to one another so right click to

cancel and just have selection select

those two press shift e and that is it

done i'm gonna go to this one here this

one here shift d and that one's done and

that is that sketch already sorted out

this here is going to be my pipe sketch

i'm going to convert this over to a mesh

let's leave this here

let's head on over to w here select that

mesh of the pipe let's go for a solidify

here and i'm solidifying this one

out

by 53.

yes indeed i am there we have it so

that's this one now very quickly let's

have a little break as i tell you that

cad sketcher is very much still in

development and remember that it's not

just an add-on it's actually a project

to bring a whole bunch of cad-like

features to the world of blender but

with that said i need to say that we're

not looking to replace cad just bring

incredible features to blender so how is

all this gonna happen with your support

and it really does mean this by your

support this is completely an open

source community two bucks a month

really makes a difference especially

when we're talking about hundreds of you

it really makes this project completely

possible but remember we do need to have

an understanding of mesh modeling if you

want to take full advantage of cad light

precision inside a blender and if you

want a way of getting started with that

link to down in the description is my

free course here on youtube that tells

you everything that i know about blender

and if you want to learn blender through

projects i have a paid course down there

as well and i have to mention this but

this video is probably already out of

date because that's how fast development

is going on with cad sketcher so if you

want to be in the know right away be

sure to join the discord community once

again link down in the description now

this top bit i want to do this in two

things i want to do it the notch itself

and the notch cut out because this is

the blender sort of cad workflow which

means we're using modifiers to do these

pocketing operations i could technically

do it all the way out all at once but

i'd rather have a little bit more

control of it so i'm going to go like

that i have the back plate already set

so i'll use and create a new sketch

we're creating this sketch hiding the

mesh and this time i'm going to use the

line tool i'm just going to draw this

quite haphazardly though because if not

i'm going to over constrain the sketch a

bit it's already constrained itself

there didn't mean to do that

and then i'm going to select these two

here so select you and you gonna go with

a shift c

u and u shift c

i'm going to remove

that constraint there because everything

is already constrained on the other

sketch and that's going to sort of

translate over to this one and this one

here is called the top notch

i can't spell

there we go top notch and we're turning

that into mesh convert it brilliant w

select that up once again add that

solidify modifier and we're going to

push this out by 40 this time brilliant

make sure that that is even and we'll do

that once again but this time when we're

creating this new sketch we're thinking

that this is just the cutaway of it so

i'm actually going to call this the

notch ca for cutaway again i cannot

spell to save my life today

so there we go top notch there we have

it i'm going to hide that mesh once

again and i'm just wanting this lovely

little bit up here so we'll go with that

line once again

like i said haphazardly i'm just

creating things so that nothing is

really constrained to anything so that

i'm able to just go and select these two

later on and constrain these points like

so it's a much quicker and cleaner way

of doing things and that's it pretty

much done and dusted okay so turning

this into a mesh leaving the sketch

pressing w selecting the mesh we just

created there adding a solidify modifier

to that and i'm going to pop that out by

55 because i know that that is

definitely enough to cut all the way

through that now i could technically do

the cutting operation right now but i'm

going to leave all of the boolean

operations for the last thing now lastly

we have this little sort of support bit

here down at the bottom

and

well

there is no pretty way of doing this so

we're going to have to just hide that

back plate now take a look from this

side view here and let's create

ourselves a sketch so ctrl shift a for a

new sketch on this plane and i'm going

to call this the pipe support

and then now that i have that there i

know i'm going to be turning this into a

mesh later and i'm going to start by

creating myself a line

upwards like this i'm don't actually

need the mesh here i want to turn this

into a construction line and there's a

reason why i'm doing this i need to give

myself a whole bunch of references now

unfortunately so let's turn this alt d

and make sure that this is a 53 so we

know where it is exactly that we're

working with here and

now i know what i'm creating is going to

be around here so i want to sort of see

where that pipe bit is up at the top so

i'm going to create this

i'm going to also turn this all into

construction because i technically don't

need it in any other way i i'm going to

select these two points though go alt d

add this one to be

55

no 53

that is it and i'll select this one

select this one shift m to do a midpoint

constraint on that and then i'll select

these two here go alt d and this one

here is going to be

let's see that is 55 there that's more

like it so now i'm starting to see this

here actually i could use this line but

also take a closer look exactly what's

going on right here there is a little

bit of a something

happening look right

here that doesn't go all the way up to

here there's a little bit of a gap so

that means it's going all the way up to

that point so let's just hold off on

turning this into an actual line let's

give ourselves a little bit more of a

reference line once again so i'm going

to create myself a vertical line this

way sorry horizontal line this way and

then i'm going to select these two let's

add a distance we know that this should

be

13

and then

this one here from that line to this

line here at a distancing to this one

and this here should be 80

and then we're going to be going from

this point here to that point there with

a line so line that up

but let's see because this is going to

be round we need to go up a little bit

here so let's just add a line going

upwards so let's add a line going up

make it over here now it's over

constrained because we've got a vertical

and a coincident so what i'm going to do

here is i'm just going to select that

coincident and just delete it and you

can see now it tells us we're back to

one

point of freedom here so i'm going to

select it right here go all the way

across

and do this once again from going here

all the way back down to that point here

we are over constrained completely here

so let's just

see where are we gonna stop we don't

need this one here that one is okay that

is constraint there that is constrained

there there is one degree of freedom

left which is the height of this one

right here

let me just double check that it is so

i'm going to select these two here

let's just put in a dimension i'm going

to go for five millimeters yeah that's

looking good to me there

so now that i'm happy with that let's

leave this and create that mesh so here

we have the mesh of that one right there

i'm going to select it so w then select

it add that solidify modifier and this

is going to be 15 millimeters but we've

got to set this to zero and an even

thickness so that it's sort of

thickening it up from the middle and now

you can see why we can go from right

down here because it actually goes

around in this way like that okay now

that we have everything set in place

make sure that you save your file if you

haven't saved your file file save as and

so on and so forth now i'm going to be

using the ball tool so in case you don't

have the ball tool that is edit

preferences over here type in ball tool

make sure this is on because i'm going

to be using the shortcuts of it to sort

of bring this all together now so let's

bring this all together so we're going

to select this one select this one

select this select this and select the

back plate as the last one and then i'm

going to be using control numpad plus

and that automatically has done an

union boolean to all of these to this

mesh back here now i want to do a

cutaway boolean so i'm going to select

this one here i'll shift select this one

so it's the last one and i'll do a

control minus and there we have it all

nice and cut

into it things are looking pretty much

done and set all of these here are the

bounding boxes of all the booleans so

i'm just going to select them all and

just press h to hide them away i don't

really need them

brilliant and then lastly i want to

actually select what we've just created

here if you don't have this this is

modifier tools add-on or something like

that just look up modifiers and it's

going to be there let me just quickly

show it to you yeah modifier tools

that's how i get all of those i'm just

going to toggle the stack all the way

down we need to add one more thing here

so i'm going to add a weld modifier

right at the end make this connected i'm

going to set this to 0.1

just to make sure that it cleans up

anything that might not be right here so

now that we've got this to this state

and everything is looking great let me

just show you how this is completely

parametric so let's go over to this back

plate let's change this here we're going

to change this to i don't know 200 hit

enter there we go and we'll leave that

and it has done that we now know that

the base plate needs to be changed

because right this minute we cannot

refer to one another so let's go and do

exactly the same and here we have it

brilliant now things are going a little

bit awry up there that means we need to

sort of pump this up a little bit

because there's a little bit of a

rounding error going on there so just be

aware that things can go a little bit

strange sometimes so let's bring that

back to 150 leave that here and we're

going to go back to the back plate as

well so this one here

go back to 150 let's have that here

and 50 leave that there now if you're

having this problem continuously let's

go to that top notch cut away here and

change this over

maybe to a fast one where is it

um is that the cutaway i don't think it

is there it is cut cut away

let's change that to fast exact it's

going weird for me why are you going

weird for me well let's fix this right

now while we're at it so i'm just going

to go over to that back plate right

there and we have this right here i need

to give this just a little bit more

of room going upwards so i'm going to

actually

change the way that i have constrained

this so there's this center midpoint

constraint there i'm going to turn that

off and then i'm going to go and bring

this up

actually no well i'm not going to do

that at all what i'm going to be doing

is adding another constraint point down

here so let's add a point to this line

and then i'm going to grab this point

here grab that point here and go alt d

and change this to be

10

there and the main reason why i'm doing

that is because i want to grab u grab u

go shift m and then i'm going to bring

you and turn you into 11. so you're

popping out like that a little bit now

when i leave this that's going to edit

the cutting object that is there so it's

going to easily clean that up now this

rounding error is definitely something

that's going to be worked out on the

future i've done this model about five

times and this is the first time that

i've had that rounding error so just be

aware that sometimes you just need to

figure out workarounds to make things

work but now let's turn this into

something that is 3d printable but at

the same time being able to keep this in

a way that is sort of

parametric in a way so to do this is as

simple as literally duplicating it so

that is shift d so making sure that this

the back plate is selected i'll press

shift d now you're going to see things

go a little bit weird at this point

don't worry just right click and cancel

that you have these two back plates here

one is a duplicate one is the original

we're going to go to that duplicate and

just apply everything on it now that

everything has been applied we can press

g and move it out and this is now ready

so this here is sort of your parametric

sort of

ready to be edited model and this here

is your ready to be printed model now

there is one more thing that i would do

just before going into printing this i'm

actually taking this into edit mode so

press tab you can see

it's not exactly the cleanest thing out

there someone just select everything

with a press x and do a limited dissolve

but i want to limit this dissolve to 0.1

of a degree of change and that's already

cleaned this up a whole bunch more now

if you really wanted to get pedantic

about this we could go and really clean

this up so grab these points here join

them up with a j we can grab these

points here dissolve them with ctrl x or

just delete those completely and let's

see these here am i going to delete them

or dissolve them i'm going to dissolve

them so ctrl x

and then we have this edge here so i'll

select that edge here press ctrl x

select this point here and so on and so

forth but there's no real need to clean

this up the truth is this is 3d

printable and let me show you if i

select this i'm going to use another

add-on here this is the 3d print toolbox

you can get this over in the edit

preferences just look up 3d print

toolbox i'm going to check all this here

is perfectly fine look at that zero zero

zero zero zero if you don't know what

exactly this means i have a video all

about it as well and if you want to know

some other workflows of cad sketcher i

have a video about that as well that's

all linked in the cards or down in the

description but let's go and throw this

into a slicer now just so you can see

how this is presented both in resin

printing and filament printing and in

case you don't know how to export this

as an stl all we're going to do is

select it go file then export then go to

stl i'm going to call this my cad

sketcher stl and i'm going to make sure

that it is selected only if not i'm

going to also export that other one then

i'll export this one and i'll see you

over in my slicers so drag and dropping

this into prusa slicer right here let's

slice it up and see what comes out

it is working absolutely beautifully

there is no problems here not even an

error message from process slicer at all

so let's go and check this out for resin

printing as well here we are in cheeto

box it's a little bit big for cheater

box so let's just make it a little bit

smaller because obviously this is going

to get a bit out of hand so let's crank

this down to 50 maybe even lower still

let's go for 35

brilliant and here it is it is perfectly

usable everything is working brilliantly

here let's go there let's slice it up

just to double check and things are

right there working brilliantly yep look

at that perfect exactly what we expected

a huge thank you to my patrons you guys

are absolutely awesome and it means the

world to me without you i truly would

not have been able to make maker tales a

big thank you to my vip makers jem oz

kanak and david fernandez and if you're

enjoying what i'm making here you think

i'm worthy of your support i would love

to see you there too and by the way if

this is the first time you're jumping

into 3d modeling and 3d design for 3d

printing i have an entire free course

here on youtube that teaches you blender

all the technicalities of 3d modeling

with blender or if you want to learn

blender through actual 3d printing

product projects then head on over to

maker tails academy and that's down in

the description away anyway thank you

for watching keep making and let the

quest continue
