Slow main assembly, when using iassembly??

gma — Sat, 08 Mar 2025 13:06:21 GMT

I am experiencing significant performance issues with my main assembly in Inventor 2023. This assembly contains multiple sub-assemblies, each of which includes iAssemblies of the same type. When I select these sub-assemblies containing iAssemblies with my mouse cursor and attempt to right-click to bring up the context menu, there is a delay of several seconds before the assembly responds.

Specific Issues:

Significant delay when right-clicking on specific sub-assemblies containing a certain type of iAssembly.
The overall responsiveness of the main assembly is slow.
Interestingly, I have other sub-assemblies with different types of iAssemblies, and I do not experience any performance issues with those.

Questions:

What could be causing this slow performance specifically with this type of iAssembly?
Are there any specific Inventor settings or best practices that can help improve performance in this situation?
Are there known issues with this specific type of iAssembly in large assemblies?

Any insights or suggestions would be greatly appreciated.

Hi! Is Express Mode turned on (Tools -> App Options -> Assembly -> "Enable Express Mode")? Try turning it off. Does it help?

If no, please share the files that exhibit the behavior with me directly (johnson.shiue@autodesk.com). I would like to understand the performance issue better.

Many thanks!

Hi,

Thanks for your reply... I'll get back to you...
We're having problems with Inventor crashing quite often and we need to get that resolved first.
