Assigning materials to exported GH objects in revit

I have exported a series of surfaces to revit. I would like to assign a mesh material to them, however Revit doesn't seem to like it.

i thought explode would be what i wanted, but that just deleted the object all together.

many thanks collective brain

what are you trying to do in revit?

Revit should be able to read Rhino Surfaces and BReps jsut fine. No need to convert to mesh or explode it.

hello, i''ve attached a rhino and GH files just in case (i'm not sure they'll actually be of any use)

I've been exporting the objects as .sat files and then linking them. However they appear as block instances (it doesn't actually refer to them as that, but you know what i mean) they are single reference objects.

i had originally been linking the files and thought maybe that was the problem, but its the same when i import it.

i did mention before but i really feel like the fact that revit isn't recognising individual components and is instead referencing a 'grouped' or single element is the problem, however i'm not sure.

OOO i almost forgot, i have been using 'in-place mass' for the first time the other day and found it really easy to create a mass, create the glazing system and apply to face.

elsewhere in this scheme (altho sep GH file) i calculated some geometry (simple surfaces extruded upwards 4.5m - the curvature on plan is the key) anyway i was hoping i would be able to use the GH geometry to allow me to place curtain wall systems, is this possible?

It's some time since I tried to use Rhino and Revit. So until I confim or someone says different, this is just from the top of my head:

Revit imports/links files to projects pretty stupidly. They are just there, you can snap to them. End of line. You can explode blocks and groups but for STL objects that means exploding to the next lower level. Which is the lines and points defining the geometry. (And I think linked files can't even be exploded)

To use the Rhino masses, I had to create a new massing family (could be in-place). I think you had to define surfaces on that STL geometry. Finally you load that family into the project file and use as you did with in-place mass.

I had some serious trouble with Rhino geometry not being imported correctly. A doubly curved wall, connected to curved walls... All nice in Rhino but the edges wouldn't meet and trim correctly in Revit. Might have been an STL issue. Nevertheles I ended up recreating the volume in Revit with massing tools.

While Revit is really powerfull in most cases, curved walls are a pain soemtimes. After I had my mass, I applied walls to them but I could never get more than 3 wall corners to join and clean up... hope you're faring better.

After cooking the geometry can be exported in. SAT. In revit you can create a genericmass and then you can apply walls to the faces of the geometry generated in GH.

hi. but how would you apply material to a sat model. in revit.

Permalink Reply by fernando molas garcia on April 9, 2012 at 6:32pm

The model exported in. Sat is used as a mass model, which you can apply walls, floors on their faces.

It is the only way I found to correlate with revit GH.

Anyone know another method?

I believe you can apply single materials to masses but you need a wall family for a wall material. So there's no other way than defining a wall (or floor or roof...) on top of the imported mass and live with all the problems revit has joining and cleaning complex edges.
