Changing Image Quality of part gets reverted back to previous value in assembly

Question asked by Gustav Rydn on Oct 14, 2020

I have experienced my assemblies to become slow when the number of parts, mates and references increase.


I used the Assembly Visualization tool and found a part "Part A" that had a high number of triangles (50.000 or so).


I opened the Part A and changed its Image Quality to the lowest setting and then saved the part.


Then by opening the assembly, rebuilding it and using the Assembly Visualization tool again, I could see a decrease in the amount of triangles (to about 16.000).


"Great!" I thought and did the same thing to another part "Part B", also resulting in a decrease of triangles. But somehow the image quality of Part A now returned to its previous value... ...and eventually at some moment Part B also returned to its previous value.


Worth noticing is that Part A is inserted into the top-assembly and Part B is inserted into a subassembly


What sorcery is going on here?
