HOW TO: Convert a Block


Setup Assumptions

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

  • Revit Requirements: None
  • Rhino Requirements: Blocks defined by a collection of solids or meshes. Instances are set to a Conveyor component family category.

Workflow with Rhino – Block

1. (Rhino) Select a series of solids and make them a block

Supported blocks are made up of solids and mesh Rhino objects. Select a collection of objects and turn them into a Rhino block with an origin point and name.

2. (Rhino) Copy a series of block instances

Copy the block to create several instances in the Rhino document. Conveyor supports copies that have been moved or possess Z-axis rotation. (transformations such as mirror, shear, or scale are not supported)

3. (Rhino) Assign block instances to a Conveyor category

Assign the block instances to the Conveyor components category and specify an available Revit category (such as Generic Models)

Save the Rhino file.

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

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

5. (Revit) Load the Block Definitions as a Revit Family

When loading the block instances, Conveyor will prompt you to load the block definitions first to create the families.

5. (Revit) Load Selected Instances

Load the block instances into the Revit document.


Modify and Update Block Families

1. (Rhino) Edit the block definition

Double-click into a Rhino block. Perform geometry edits to objects. Users can also and/or delete objects from the block.

2. (Rhino) Move a block instance

Move or rotate the block instances to new positions in the Rhino document.

Save the Rhino file.

3. (Revit) Refresh the file in Rhino Conveyor and review changes

Review the changes to the element list. The element list will highlight the Instances that will be re-positioned in Revit.

4. (Revit) Reload the block instances

Users will first be prompted to reload the block definition – this is optional if you do not want to update the Revit family geometry.

After load, the Family instances will be re-positioned (moved or rotated)

Known Issues

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

  • Nested blocks are not supported in this version of Conveyor.
  • Highly irregular or self-intersecting surface and solid geometry may not import due to Revit geometry limitations.
