I have a rather large model, it never used to be slow ( could cut around 550 sections in about 5 minutes) but now has slowed to a halt or crash. I have tried cutting them through a "section" file with the models attached there and from the base model file. Does anyone have any thoughts on getting this file to process sections quicker? When I try to do dynamic sections, microstation grinds a halt until it process the 3D model very slowly. Any ideas are helpful! Thanks in advance!
