I have a BIG assembly with parts and surfaces. Of this I only need a relatively small cutout through the XY plane.
I tried extrude cut but that won't include the surfaces, and it will still calculate everything before the cut, right?
anyone have experience with solving this?
Inventor standard 2012, 12GB of RAM,.
Thank you for having posted your question on the discussion group.
Sorry if you already know this information, but here are interesting links on this subject
For temporary visibility purposes, you could use “Assembly Section Views” in an assembly:
For capacity and performance purposes, you could use “LOD (Level of details)” combined with “substitutes”.
Here is a link providing additional tips helping to work with “large assemblies”
I hope that will help

Hi, and thanks for your reply.
My issue is definitely about capacity and performance. I am familiar with the LOD and substitutes but they seem to affect whole parts or assemblies. In some cases, a spherical or cubical "spotlight" that suppresses everything outside would be perfect to spend the performance and capacity exactly where it is needed. [edit: -or that the section views helped to free up load on ram and cpu+gpu.]
My attempt at this was to derive the assembly, cut unneeded geometry in the derive, then derive that again, and break/suppress the link. But I can't get this to work when the assembly includes surfaces.
Thanks for your answer.
Maybe you already know this tip but which could be interesting for other users of Inventor….
Inventor provides the possibility in an assembly to select, in a very easy way all the components, for example included in a selected feature like a sphere, a rectangle, constrained to a specific component or to a subassembly, on one side of a plan, according to their sizes,….
> Open the assembly > Right Mouse Button > Selection > and after choose the most appropriate filter you need. After selection you could for example suppress (temporary) the selected components or isolate them which would probably help the performances.

To help you in large assemblies, you could also adjust some settings (application options) with lower values (see specifically the section “Tools and methodologies”> “Application options” of this web page)
