Is there any way to step through the Inventor Document Update process in order to diagnose crashes or 'hangups'?
Inventor 2014 hangs up and crashes often for us in a variety of models due to what seems to be a problem with how Inventor updates parts with multiple levels of derivation. The use of blocks may also play a factor in this.
Our models are structured like this:
1. Profiles .ipt : Individual ipt files each containing a profile block used in many places. All sketch blocks are fully constrained following best practices.
2. Master Sketch .ipt : Ten to twenty ".ipt profile blocks" are derived into a master sketch file and used to create a skeleton sketch.
3. Subassemblies .ipt : This master sketch file is derived into numerous multi-body solid parts which will each form a different sub-assembly.
The problem seems to be between level 3 and level 2. If you open the Master Sketch, it is completely up to date. When you open one of the multi-body solids, it will show that the derivation from the master sketch needs updating, but when you update it, Inventor hangs indefinitely, even though the update bar often keeps moving for hours.
These are not complex assemblies. There are perhaps 20 profiles derived into each Master Sketch and only one Master Sketch derived into any given Multi-body solid. With a lot of trial and error you can sometimes figure out where the problem lies, but if there was a way to step through the update process for the Master Sketch manually or using iLogic, then we could better diagnose where the problem lies and see if we can fix that component so that the document will update. Currently we sometimes end up rebuilding a multi-body solid because we can't get it to work any other way.
Any ideas for diagnosis are welcome.
