Importing Revit

[Chris MacDonald]

I appreciate we already have a dozen topics on this, but this one is fairly specific.

 

If you've clicked this thread then I am going to assume you already know how absolutely spastic some of the imported Revit geometry can be, especially when it comes to chamfered/curved objects.

 

I've just imported a building which is all as you'd come to expect from Revit, not great but it'll do. The problem however is that the upper portion of the building is covered in louvre blades, as is one of the stair cores - and this bit of geometry alone weighs in at a staggering 12,000,000 polygons. Yes, 12 million polygons for some louvres.

 

As usual with Revit imports, you can't see anything unusual about the geometry until you look at the vertices, at which point you see a sea of blue dots engulf your screen, none of them apparently connected to any of the others.

 

Has anybody found a way of cleaning up this particular type of infuriating geometry? I'm struggling to write this without resorting to copious amounts of expletives.

 

What absolute chimp wrote the import filters for this?!

Sorry cant help but I really feel your pain, I do hate revit models always heavy even the simplest ones!

[Justin Hunt]

for curved objects .DWG works better. The revit imported in Max is really just converting the revit file to an FBX file and importing that.

Thanks chaps,

 

I think I might just go and play in traffic.

I would import that section separate and use prooptimizer to try to clean it up as best as possible. The other option would be to recreate it in Max and use the rest of the import as is.
