ACIS (.SAT) files not cutting correctly in Section

It’s been 2 months since by last post. Work has been very busy, I also just started as REVIC chairperson (Revit users group of Victoria Australia) and I’ve been enjoying our nice long Christmas break.
We started to try importing ACIS (SAT) files into Revit from Rino. The reason for going via ACIS was as some of the geometry was curved. You may know, when you try to import a curved dwg file geometry into Revit, it comes in with triangulated faces and thus is very messy when viewed. ACIS can be exported from Rino to avoid this.
The ACIS files did in general export without a problem out of Rino. During the import process the files were imported into an external generic model family (we also tried an in-place family). However when we took a section in one direction It did not cut correctly (I looked like an elevation). Cutting the section in the other direction worked fine. We tried all the various different SAT exports in Rino and tried some different geometry and the same issue happened. Importing using the same method with a dwg file worked fine.
We have made Autodesk aware of the problem which they acknowledge and they are chasing it up with their Revit development team. I have not come across a direct workaround for this problem. My advice, avoid ACIS file imports where you want them to cut in section until Autodesk resolve the issue.

Hi Brian, any further news on this issue?

Thanks

Ran across a similar issue - in my case it was size/complexity of the import. We solved that by creating multiple parts and importing them separately....

If you create an in-place mass or family then import the .sat file....revit will cut the section properly.
