While the issue with multibody drawings was solved, today I made another quick test with a very big multibody model: over 1400 bodies. Rebuild time 17s
We should not use SW that way, and honestly I would prefer to have a master model assy instead of a big single part file.
2D slow as hell on a Z4 G4 4.2Ghz 32GB RAM SSD
I brought down the rebuild time at around 10 seconds, but the drawing was still slow.
My empirical observation is the faster the model, the faster is its 2D drawing response.
So I exported the 1400+ bodies in a parasolid file and imported back in SW: Rebuild time 0 seconds and you can make the section views almost on the fly with little lag.
Obviously zero parameters, but the alternative would be no drawing or a week to make a page…
