How do you snap onto objects
How do you snap onto objects
(OP)
Im used to solid works solid edge and autodesk inventor. Im starting to try out catia v5. How do you snap lines onto objects when drawing new objects in sketch mode or when trying to move a sketched object? I cant seem to do this.
Say you already have an extruded part. Then on a surface you do another sketch that will be used for extrusion or cut. How do you snap newly drawn sketch objects to the extruded geometry?

This simple tutorial will probably help you more than any of my written words...
P.S.: This guy has a lot of simple CATIA tutorials and are gold for a beginner.
Best of luck!

I think I figured out a way that seems to be as close as what I am used to with other CAD. I used the "project 3d elements" command to project existing features first, then I was able to use those lines for some feature snapping. I dont know if this is the normal or preferred or only way of doing this. In other CAD you they normalyl allow snapping of the same part objects right away.

Projecting isn't wrong but consumes time when you shouldn't.

Do you mean you can snap onto features when doing that?
What I mean is not have to go through the extra annoying step of doing the constraint method, but being able to directly draw the geometry (e.g. circle or rectangle or line) directly on the object and have it be able to snap onto the existing object and relationships (e.g. center of an extruded circle or center of a line feature etc).
Now, I can snap onto features provided it is still the same sketch. It doersnt work if the object has already been extruded from a previous sketch.
The only way I seem to be able to do this is to project the element first.

Im still convinced catia must have this ability but I cant seem to find a setting to unlock it to be able to do this. Or does it not and the only way to snap onto existing features is with the "project 3d" command?

personnaly I wouldn't create the sketches on an existing surface, I would create a plane from a datum plane in the same place and then create the sketch on that. depending how complex your parts are, if you start creating sketches on existing surfaces it will cause frustrating problems later on.
I haven't used solid works though so hope that helps.
