HOW TO: Convert a Grid


Setup Assumptions

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

  • Revit Requirements: A Revit document with grid annotation.
  • Rhino Requirements: A line curve or arc curve assigned to a Conveyor grid category with the name property indicating the Grid name.

Workflow with Rhino – Line and Arc

1. (Rhino) Draw line or arc curves

Draw curves using line or arc commands in Rhino to be compatible with Revit grids.

2. (Rhino) Assign the curve to a the grid category with a name

Assign the Lines and Arcs to the Grids category in Conveyor. Provide a grid name to each of the curves.

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

4. (Revit) Load selected grid elements in Revit

Load the selected grids into the Revit model.


Modify and Update Grids

1. (Rhino) Move the grid curve in Rhino

Move or rotate the Rhino grid curves.

Save the Rhino file.

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

Refresh the Rhino file in the Rhino Conveyor panel. Review the updated elements for changes.

2. (Revit) Load the Updates

Reload the updated grids. The previous grids will be replaced with update grids.


Known Issues

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

  • Revit can only use Line and Arc data to create grids. Complex curves are not supported.
  • Conflicting or duplicate Grid names may result in import errors in Revit.
