Tutorials for collision testing
(OP)
Hello Everyone!
I'm trying to build an Assembly and would like to test if there are collisions. I've looked in the Tutorials and the help files that are included with SE, but wasn't to find anything on "Motion" (there is some info, but no very deep).
Could you please point me some tutorials or help files where the collision-test is discussed?
Cheers!

RE: Tutorials for collision testing
Motion is analized with the move command on the assembly toolbar. I found the best way to learn its different feature is to create a simple test assembly and try it out. You can detect collisions with both a selection of parts or the entire assembly.
The part that you are moving must be under constrained. If you have it fully constrained you can suppress some of them.
Example: You have a linkage with two bars pinned together on there ends. One bar is grounded. The other bar may have a mate constraint to hold them face to face. It may also have a concentric constraint to hold the pivot pin location.
You can move the second bar with the move command because it can only pivot around the pin.

Thanks for the reply. I've been playing with the move command, and got some results. One thing I've learned with SE, is that it has A LOT MORE to offer than what you see with the naked eye.
I used to work with Solid Works. There there are 3 types of movementes for parts that are underdefined. With the forst you kann move the underdefined part THROUGH the others. With the second you can move it until it "touches" another part, then ist will stop moving and a collision will be shown. And with the third "dynamic movement" you can make chains of movements. That means, I grab part1. If it touches a part that is underdefined aswell this second part will be moved too and so on.
This last movement type is what I want to do in SE, but havent been able. If you ever find some tutorial or exercices in "movement" I would really appreciate if you could post the link here.
Cheers!

Now I fell really dumb, for not finding that tab. Thank you very much for the tip!!!
