CAD geometry from Autodesk Revit

Using SimScale CAD & Meshing
2

Hi @jstirling!

I have no experience with Autodesk Revit but would like to suggest another solution.

OnShape is able to perform a Boolean Subtraction! By defining the boundaries around the geometry subtracting the starting CAD model from the domain that will be simulated will provide you with the Volume you were looking for.

Steps that have to be done:

  1. Upload your geometry to OnShape

  2. Define your boundaries by sketching around your object (or some other operation if needed)

  3. Select Boolean operation from the panel, choose the components that need to be subtracted and switch to Subtract in the menu

  4. Click the checkmark (you can use the right-click option “Shaded with Hidden Edges” to see the geometry inside your domain if applicable)

Additional Information: You can directly import your part files from SolidWorks, Autodesk Inventor and Rhino. It is also possible to upload assemblies in compressed archives (*.zip, *.tar.gz). Find a list of the supported file extensions below:

  • STEP
  • IGES
  • STL
  • *.sldprt SolidWorks part
  • *.sldasm SolidWorks assembly (in compressed archive)
  • *.ipt Autodesk Inventor part
  • *.iam Autodesk Inventor assembly (in compressed archive)
  • *.3dm Rhino part

Tell me if that worked for you and maybe one of our @power_users has already used Autodesk (Revit) and might give you the step-by-step instruction.

Cheers!
