About the Solidify Feature
The Solidify feature uses existing quilts or datum planes to create or modify solid geometry. You can use Solidify to add, remove, or replace solid geometry in your designs.
The following is a typical workflow using Solidify:
• Select a surface feature or quilt as a reference
• Determine how you want to use the reference geometry: add solid geometry, remove solid geometry, or patch a surface
• Define the direction for the geometry
To open the Solidify tool, select a surface feature, quilt, or datum plane, and then click > 
Solidify.
Solidify.The following Solidify feature types are available:
Type | Surface or Quilt | Solidify |
