HOW TO: Convert a Wall (Extruded and Face-Based)


Setup Assumptions

This article describes how to convert wall geometry from Rhino to Revit with the Conveyor tools.

  • Revit Requirements: A Revit document with loaded wall types and levels.
  • Rhino Requirements: Extruded planar surfaces with assigned wall type.

Workflow with Rhino – Extruded Surface

1. (Rhino) Create extruded surfaces

Extrude surfaces from line or arc curves.

2. (Rhino) Assign surfaces to wall category with type

Assign the surfaces to a wall category and family type.

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 wall object(s). Verify the listing of elements and select as needed.

4. (Revit) Load selected wall elements into Revit

Click the “Load Rhino Objects” button to load the walls. The walls will be created as native Revit walls with the wall type using the wall surface as the “centerline”.

Modify and Update Wall

1. (Rhino) Modify the existing walls

Edit the wall surface in Rhino using tools like moving edge or moving the object.

Save the Rhino file.

2. (Revit) Refresh the file in Rhino Conveyor to review changes

Review available updates to the wall objects.

3. (Revit) Load the updates

Load the updated Revit walls. Conveyor will re-recreate the walls with the new geometry. (Note: walls are re-created elements IDs will change)

Workflow with Rhino – Wall by Face

1. (Rhino) Create complex surface representing face of wall

Define a surface representing the face of a wall. These objects can have complex curvature and trims.

2. (Rhino) Assign the surface to a Walls-FaceBased type

Assign the surface to a Walls-FaceBased category and type.

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 wall object(s). Verify the listing of elements and select as needed.

4. (Revit) Import Load Selected Wall Elements

Load the selected walls into the Revit document. Verify that the wall has been created with the defined type.

Known Limitations

Converted walls are known to have the following limitations:

  • Normal extruded walls are always defined by the “centerline” location. The Revit API does not allow a created wall using other Location Line definitions.
  • Wall by Face are slower to import because they require temporary masses be created. Their geometry cannot be edited afterwards.
