HOW TO: Convert a SubD

Supported Version: v1.0 and v2.0

Setup Assumptions

This article describes how to convert SubD geometry from Rhino (v7.0 only) to Revit with the Conveyor tools.

  • Revit Requirements: None
  • Rhino Requirements: A Rhino SubD object assigned to a Conveyor mesh category.

Workflow with Rhino – SubD Object

1. (Rhino) Create a Rhino SubD object (Rhino v7)

Define a SubD object in Rhino 7.

2. (Rhino) Assign the SubD to a Conveyor category

Assign the SubD object to a mesh Conveyor layer with a Revit category.

Save the Rhino file.

3. (Revit) Launch Rhino Conveyor and select saved Rhino 3DM file

In the Rhino Conveyor panel, select the Rhino 3DM containing the SubD object(s). Verify the listing of elements and select as needed.

(optional) To control the mesh resolution of the import, you can adjust the mesh Subdivision settings. The default is 3. Higher numbers will product smoother meshes. Fewer will produce coarser meshes.

4. (Revit) Load the SubD objects

Click the “Load Rhino Objects” button to load the SubD objects. The SubD meshes will be created as families assigned to the Revit category

Known Issues

The following represents a list of known issues and limitations with importing SubD objects using Conveyor:

  • Imported SubD meshes cannot have materials directly assigned to them.
  • Users will need to use visibility graphic overrides or object styles to control the graphics of the imported SubD mesh.
