Cross sections cutting slow from corridor model

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!

  • Mark,

    The closest thing I can attribute to doing would be updating the existing terrain, and then updating the DTM.dgn via the refresh from source tool. It was after that I began to run into this. But at this point my model is tied to that DTM.dgn and any attempt to switch it for a different file results in corruption. I can't say 100% that updating the DTM from source was the cause, but that is the only thing I can recall doing that would have made a difference.
