Re: Fix problem introduced in Creo 3 Creo Simulate fasteners and materials fail instead of being suppressed while in a simplified rep causing meshing failures and analysis running failures or to terminate and fail.

Need a SPR to restore functionality, but I voted up on the idea anyway.  I suppressed one of the components in Parametric before switching to Simulate, as shown below.  I didn't see the suppressed black box in your model tree for Creo 3.  Good find.
