Revit Geometry

Hi,

I am trying to figure out if there is a simple/easy way to get glass geometry out of Revit as a single surface (per glazing unit) rather than as a solid with thickness? I suppose if the solid has uniformly oriented normals then the glass geometry could use a dielectric material, but I am not sure how negatively this might impact simulation time.

Any Revit users out there, thoughts on modifying a window "family" to do this?

Thanks,

-Jack

Be great if there was a way to do this with SketchUp glazing geometry too...

Hi Rob,

Well my preliminary test would suggest that at least the normals are oriented uniformly. Do you have a sense for how a dielectric could slow things down?

Hi Jack,

I think that the Blender mesh editing function "remove doubles" works
fine for this type of glazing models problems.

It "welds" vertices that are within a certain selectable radius:

Hi Francesco,

Ahh! That is an interesting idea. I will try that in Polytrans, which has a variety of functionality for processing geometry.

Thanks,
