    Can you cut imported geometry

    Is it possible to model something in Rhino, Sketchup or Autocad and cut it with a revit void?

    I've tried various combinations:

    - using in place voids vs face based void families
    - including the imported geometry in families vs import directly in the projects
    - importing solid geometry vs surface geometry
    - using different file formats (.sat, ,3dm, .dwg)
    - using linking vs importing

    but I'm having a hard time figuring it out. The tests seem to suggest that:

    - you can't cut surface geometry?
    - you can't cut imported geometry with an inplace family?
    - you can cut imported solid geometry with a face based family?
    - file format does not seem to matter much as long as it contains surface geometry?
    - cutting does not work with linked geometry?

    We often do specialty items in our spaces (for example: complicated ceiling). A big part of our staff finds it easier to create that in Rhino. I'm trying to figure out whether there's a workflow where we can make the general shape in Rhino and then add voids in Revit for example for the light fixtures etc. Right now we have to do part of the coordination in Rhino (for example cut out openings for air terminals, lights etc) and it's a PITA.

    The way people have always done it is to first link it into a Generic Model first. This is usually best achieved by using a "sacrificial project model" and linking the export into an In-Place Model, in which you would think Link into your current Revit project. I believe later versions of Revit has done away with this possibility.

      Been working with 2014 for a while but I think one can still link a DWG file inside a SF or GM in 2017 release.
      For 2018 release , my question would be.. is it possible to use new underlay methods AND BE CUTABLE?

      In other words, What does it mean when the voiceover says
      "..they appear .." ?

        Star with a conceptual mass family, import the CAD into it, and then load it into your project. It should cut fine.

          Thank you for your answers.

          I'm looking to actually cut an imported geometry (for example: complex ceiling modeled in Rhino) with Revit voids (preferably in place voids). Importing geometry in masses works great if you want to have them cut by the cut plane, but this does not seem to help with what I'm trying to achieve.

          I did not realize that you could link in geometry if you're using in place families (as opposed to normal families). However, even than, I cannot seem to cut the linked geometry with voids (be it in the same inplace family or in a separate family).

          Could it be that this is not possible and cutting with voids should be done in the software where the imported/linked geometry was created?

            As far as I know, voids will certainly not work. It has to be native Revit geometry for Revit's void system to cut. I thought you were referring to "being cuttable" as in sections views in a project. I would not know of an advanced solution for this, but maybe someone will post with something that you can work with.

              Revit 2017 API can convert SAT/3DM into "native" Revit object (DirectShape, can assign category/material, even though it's not 100% Revit native) -> ShapeImporter.Convert()
