Where is my + - symbol next to my part or main assy in the browser?

Why can't I reorder parts in the browser?

Lastly, I would like to model some Pneumatic assemblies... When 1 part
pushes air, the other part moves. How would I simulate this? The Motion
constraint offerings are not what I need, because nothing "spins".

Ideas?

Don't know about the +- symbol.

The ability to reorder the parts in the browser was taken out in V6 to not
cause problems with assembly features. An Adesk guy explained it in a
message a few days ago.

The best way to simulate this would be by defining the position constraints
using equations. If you know the relationship between the 2 cylinders (say
part 1 moves 1in. for every 2 that part 2 moves) you can define one part's
position as a function of the other.

The (+) is gone. Why did you need it anyway?

My guess is that the extra browser space to show that little "+" (which
effected the entire browser vertically) was considered too big a price to
pay, just to be able to minimize the entire tree.

The new ability in R6 to create assembly features caused a problem with
moving parts around in the browser. A lot of us are missing that ability a
great deal. Last I heard, Autodesk was looking for a solution that would
allow rearranging the assembly tree again. Having order-dependent features
in a part doesn't preclude moving part features, since the ones that don't
work any more just raise a flag. I would hope they could find a similar
method for assemblies.

You can drive a linear constraint with the drive constraints function.
Right-click on the constraint in the browser to access that function. You
can tweak the offset value of a linear constraint there.

Cheers,
Walt
