Drawing Parts List making an iAssembly factory Dirty.

[awatt]

I have an iAssembly that on its own is quite stable.

I can put views of various members in a drawing with no problem.

The moment I add a Parts list (for any member or combination), the factory becomes dirty, and saving results in out-of-date member problems.

I can get everything updated at the same time, save, and start the whole cycle over again when I re-open the drawing.

Any ideas what I am missing?

I kind of think thats fairly normal/common..

Inventor has always complained about iassy members getting dirty when you don't think you are doing anything to them..

I am always opening the factory and doing a rebuild all/generate

. . Except this isn't about the members needing updated.  It's about the factory. EVERY time i open the drawing after putting in the parts list.

I've also ruled out ilogic triggers.

Hi! Based on your description, this sounds like the designed behavior. When you create a PartsList, the object actually derives the data from BOM table. If the BOM table views were not enabled, Inventor will enable the BOM view and dirty the assembly file (iassembly factory).

If this does not make sense, please share an example so forum experts can take a closer look.

Many thanks!

If I understand you, you're talking about the 'enable BOM View' option in the Assembly Bill of materials table, structured tab.  Mine has always been enabled.

However, on further experimentation, I've discovered the drawing may not be to blame.

I think the root of the problem was unmigrated components in the assembly.  Even though nothing showed as dirty, I checked EVERYTHING out of the vault, rebuilt all, and checked it back in.  After a couple of rebuild all / generate file cycles, I got the model to stabilize.
