tutorial number 7 it will be about the contact constraint very nice tool and

catia this got a description if you didn't know what to find it for example if

the menus are messed up you can send them back as they were so practically on

this and the button of it you can see customize here you can see so you can

go to the tool customize and the toolbar restore all contents and

restore all position close so now the original interface returned back so now

let's choose plane to sketch on it xy plane and choose the sketch workbench and

let's try to draw some rectangle and circle so the contact constraint is a tool

making a contact between two objects where the contacts is available to them

so in this case let's try with this circle and with one edge of rectangle just

press on the auto contact or contact constraint choose this circle and this

edge so now you are able to move this circle tangent to this edge and as you

notice the size of the circle is changed because we did it at other mentioned

constraint so let's make another case let's make this line make the contact

with this rectangle edge contact constraint this one is already choose and it

choose this so now we're making this contact or the collinear relation to this

line edge and if we draw two circle we have or the one circle is draw a second

circle and let's make contact constraint between this circle and this circle

so we have this smaller circle is considering with the bigger circle and you

will see the constraint relation is applied here and now you can move this

circle tangent to this edge if you want to move the relation between for

example this line and this edge you have this consider consider relation and

basically now you can move this line freely so let's make another case let's

choose the profile draw line hold circle and arc and another and one line so now

let's make a contact constraint between this circle and this line let's

choose the what constraint let's choose this arc and this line so we made the

contact constraint and this profile so now we showed you many examples how to

use the auto constraint or the contact constraint in cathear and see you in the

next tutorial
