Hi, when I import my revit file into 3ds Max, my poly count becomes huge (900k) and the model becomes very hard to work with in Max. Now, in Revit i am trying to limit my geometry. I have a large amount of glazing and mullions that need to be modelled. It appears that my mullions are being modelled in between every glazed panel (see attached image). This is creating a huge number of mullions! I have tried to change the join condition in my curtain panels to be continuous but this still happens. Is there any way to fix this? Or, is there an overall way to join geometry and limit my poly count (groups won't work).

Thanks!

more geometry and more polys does slow down max. I could just make the mechanical penthouse that is shown in the attached image a texture for rendering in 3ds max but wanted to see if there was a way to simplify it. That's my problem, that's why I'm asking. My mullion is the standard quad mullion from Revit, I believe it is just a regular square sweep...

Each mullion segment (between curtain grids) will be its own polygon as yu have discovered.  Joining them in Revit is a graphic condition only inside Revit but they will export as seperate objects.

Some ideas to consider:

1. In Revit model the louvers as a curtain panel with a surface pattern of model lines rather than as individual mullions.  This of course depends on the purpose of the Revit model and why the mullion method for louvers was choosen (I do show this method to most of my clients so I may be the guilty party!)

2.  Rather than exporting the entire model to Max, pick what you want to export.  Create a 3D view specifically for the Max export.  In the Max export view turn off the categories you don't want exported.  If you are simply doing an exterior rendering for example you can turn off furniture, ceilings, plubming fixtures etc. to lower the polygon count.  For the curtain wall louvers you will likely have to establish a view filter to turn off targeted elements or hover over an object and right click and use the "hide in view" "element" method.  All of the visibility graphic over-rides in Revit are view specific so changing them in your Max export view will not affect any other view in the project.

With the things off you don't want from Revit you can model them in Max using the lower polygon method you described.  If you export the Mex export view from Revit as a .dwg and link into Max then future Revit exports will update inside of Max.  You will of course have to manually manage the geometry you created in Max.
