Why do IvSheetMetalPart based designs slow down my ETO application so much? Is there a way to tune my application?

I work with Inventor ETO 2013 R2 / Windows 7 64 bit

Dieter:

Are there a lot of punch patterns?

Can you file a issue with ADN and send them a sample?  This has come up before, but we need to see the case to give better info.

Hi Jack, The issue is the same without punch patterns. I filed the issue with ADN and sent the attached sample. ?I have attached a sample design to explain the issue. In this design you can choose a sheet design or a no_sheet design. No_sheet design is 10 times faster than the sheet design.. In my ETO application there are a great number of sheet parts with a lot of holes (IvSMPartPunchFeature). The IvShettMetalParts are extremely time consuming. How can we tune that. ?

Yes, when I said "punch patterns" I meant "lots of punch features".  These are known to be time-consuming.  We are gathering recommendations.  One recommendation is around the flat patterns.  If you are not planning to use the Flat Patterns, you can delete them in the factory parts, and re-adopt IPTs. That will give some time gain, because the Flat Patterns updates tend to be slow.

If you just make a change in Inventor (without Intent/ETO) on the IPT, a simple change takes about 3 seconds, which is fairly slow.  ETO can't make Inventor faster.  If you have many such parts, you are going to be taking that kind of time per part.  Of course, once they are cached, they are almost instaneous.

One strategy is to avoid the slow stuff with conditionals until you need the full monty.
