Question about how to handle rivets.
Question about how to handle rivets.
(OP)
We currently have our rivets modeled with in the uncrushed state with a huck on the end and the mandrel in tact. When we place the rivet we put one in and use flexibility to remove the mandrel and set the crush depth to the desired length. We then can use the repeat command to place the rivet in the rest of the holes. This creates a problem with long regeneration times, especially if there are 1000+ rivets.
I have considered using simplified reps and that works too, except it is quite involved to put in different depths into the model. If this is done, you either cannot use the repeat command or you have to create a simplified rep in the assembly and subsitute the rivet rep. This works as well but if you want to put that assembly in a drawing or another assembly you have to use the correct rep.
These are what I have found out so far. I am open to suggestions. We are using WF 2.0.

RE: Question about how to handle rivets.
I'd definately use simplified reps and have one without the rivits to work with most of the time. I see no reason to model both virgin and assembled states of the rivit.
I haven't found a way to model using any large quantity of fasteners that doesn't slow down Pro-E, or even Solidworks for that matter.
I've done some high cavitation mold designs, and gave up modeling every cavity. It wasted computing time, especially when trying to copy a change to all cavities. If it's seperate mold inserts, I model one, and leave the rest empty in the aseembly. If it's multiple parts cut into one large core/cavity isnert, I often did only one part, and used notes to instruct the machine shop on what to do about the rest (Copied 100X at X x X.XX spacing) or something.
