Fix Geometry in Pathfinder Models Created From DWG Files

In this video we show how to fix geometry problems that can result when a Pathfinder model is created using an imported DWG file.

The problems arise because the primary focus of an architectural model is the visual representation of the design, so it is not necessary that every geometric detail is exactly correct. As a result, it is possible to have small gaps or misalignments of geometry in the architectural model. When this geometry is used to extract the Pathfinder navigation mesh, it can result in rooms not being connected or other problems.
