Pos Rep Question

[SteveFrey]

I have an assembly with 2 pos reps.  When I activate one or the other of the pos reps the whole assembly jumps.  I have the main part grounded.  I tried to ground other parts but this still happens.  Any idea why this happens and how to fix it?

Is the assembly actually changing position relative to the origin, or is the view just panning?

the assembly looks like it is changing position.  I noticed it in the .IDW.

Maybe it is just the drawing view moving on the sheet?  You can verify if the assembly is actually changing position relative to the origin by measuring the distance between a component and an origin plane in one positional rep, then change the positional rep and measure between the same two entities.  If the distance is not the same, then that component has moved.

If it is just the drawing view moving, then there is something else going on.

Also, if you can post a data set, it would help.

I figured it out.  I replaced the "base" or original grounded part.  Seems to work now.  Thanks.
