Taking models from Revit to Cura

[uncluesteve 0]

I am looking for some tips or tricks to get good results from printing models that are generated from Autodesk's Revit software. Right now I am exporting to 3DS Max, doing some minor clean up then exporting to STL. I get descent results for large parts, but for details parts there are usually lots of missing faces in the polymesh objects that cause a lot of issues with cura.
