Delete Double Faces

[glorybound]

I have a ton of double faces from a Revit model. Anyway to find and delete these? I found a couple scripts, but they did nothing.

Yeah, I'd really like to know this too - a real pain in the a** for furniture models off manufacturer websites.

[glorybound]

I did find one script that worked, kind of. My problem is thin walled objects where the inside is facing out and the outside is facing it, however, only on part of the object. In my case, Revit railings. It also had double faces.

DON'T use revit models. Sorry I don't have anything better to add than that. I always redraw the whole f-ing revit model. They are just worthless. You'll honestly be faster redrawing the whole thing than cleaning that piece of **** geometry.

The only issue with this model seems to be the railing, which I'll probably model over.

I had the exact same problem as you very recently Bobby : a large revit model where railings caused huge problems. After fighting for a few hours I just removed them and rebuilt them with Railclone.
The model itself was actually incredibly clean compared to what I get from archicad and sketchup. I didn't need to remodel anything except the railings.

If you export curved objects like railings as DWGs from Revit, then you'll get a much cleaner imported model. Don't know why FBX and Revit linking screw curved surfaces up so much. Railings in general should be an item you should expect to remodel though.

[Vizioen]

You can just import revit and choose the detail of the curved objects in Max. But I refuse to work with revit models. Had my fair share of frustration, although it could be that our entire staff here doesn't know how to draw in Revit correctly or in a clean fashion.

[glorybound]

Other than the railings, the model is pretty clean.

[Vizioen]

Depends on who uses it I guess and to what ends. The models here are huge: 900 chamber hospitals with operating theaters and what not. All information is in them too. Too much for archviz needs.

That is unfortunately not a realistic option. More or less all my 3D work now comes from Revit and it seems as the adoption rate in the architecture field is just increasing. What is frustrating is that Autodesk or someone else can't make a translator/link worth the name.

[Vizioen]

It's not the translator, it's Revit not making valid geometry afaik.

[VelvetElvis]

I think it's the FBX translator. A DWG of a cylinder from Revit will give you what you'd expect from a cylinder in Max. That same cylinder from Revit brought in from an FBX (or link which uses FBX) results in a vertex bomb of the shittiest triangles. Just increasing the curved surfaces means you get an even shittier triangulated mess.

This is the same curved wall, the one on the left is DWG and the one on the right is FBX.


The issue with DWG's though is that you have to deal with the fun times of blocks and what not.

railing for me always comes in and doubled, like revit doubles up the model when it comes to railings, all of the railing itself is always doubled, idk why this always happens
