Hi,
I've searched online and on these forums. Found similar info, but nothing that has helped me. If this is redundant then please point me towards the answers if they are already posted somewhere.
I am working on a 3D BIM model for our office; it is a large (~250,000 sq.ft.) apartment building. My goal is to export the model for our engineers who are working in Revit. Ideally, I want to export directly to Revit but it is not working. I have tried export to Revit, IFC, and STEP file formats; a summary of the exports follows.
Revit exports work very very slowly until the progress bar is a fraction away from being finished and then freezes. I tried exporting the whole building including site (ambitious, I know) which took about an hour to almost finish. I left it for another hour @ a fraction of progress bar left, but it never budged and so I forced close. Tried again with only a single floor of the project in a new file - same result. Tried again with the single floor and converted symbols to groups - same result. Tried exporting a blank file with a single extrusion to revit and it worked.
IFC - taking a while but not nearly as long. Our engineers have said that if we can give them Revit instead of IFC that would save them lots of time.
STEP - found someone mention they export this format instead of IFC on the forums so I tried it. The export worked a lot faster but I don't know about this format, gonna see what the engineers think of it.
I need advice on how to fix this problem of not being able to export to Revit. Does anyone with experience here know of things to look out for that would vastly improve revit export and make it tenable? Symbol definitions need to be converted, need to use stories instead of just layer heights, no screen plane geometry allowed, etc. Other advice?
Are STEP files the future? Should I use those instead of these knavish Revit and IFC formats?
