I can't figure out how to create driving dim. I need some help to get started.

Here's a little mini tutorial I just made. Hopefully it will explain the basics of the tool.
Start playing with that and then go on and try moving faces around and then clicking the "Recalculate Model with Driving Dimensions" button to see your model adjust itself to match your changes and the "Driving Dimensions" you previously set.

BTW, this tool is great!
Now... if we could get some angles too, then I wouldn't be missing much from my SolidWorks days.

I think I'm having the same problem.

In my case it seems like there's no problem selecting faces on the sides of the model, but when I try to select a face that lies on the top, then the faces on top acts as if it wasn't there and a face underneath it is the one that actually gets selected.

If you picture a box, I go to select the top face, but SU actually selects either the bottom or one of the sides.

Weird...

No problem selecting faces.

Behavior seems to stop when using X-ray (ie. selection works like it should).

I tried ticking and unticking boxes in the preferences but that didn't work.

UPDATE: Tried once more turning off hardware acceleration and problem seems solved.

I'm having the same type of problem you mention here, where depending on the exact order I do things or if the hierarchy is just a tad different, components that (in my mind) should behave the same, sometimes have different behaviors (ie. one component might be held solid in its jointed place, while the other is wobbly).

I have yet to figure out what the preferred order to do things is so that joints will behave optimally.

Right now, this is the rough order I use to add joints, please let me know if I'm doing something wrong:
1 - Create parts
2 - Group parts into individual groups/components
3 - Create joint
4 - Attach joint to part
5 - Group joint + part
6 - Attach "joint+part group" to parent part

This generally works for simple joints, but when I try to build more complex assemblies (ie. attach a hinged component to a servo'ed component) I have very mixed results.

Any guidance or rule of thumbs to follow would be greatly appreciated.
