Geometry Contrl Tabs, Geometry Control and Manage Items Selections

The Select tab is where most Navisworks clash tests go wrong.
I willl cover the 3 Geometry Type buttons, Self-Intersect control, and the Selection Tree sync tools. By the end, you’ll know when to use Surfaces vs Lines vs Points, and how to avoid 10,000 false clash results.
WHAT YOU'LL LEARN:
✅ The difference between Surfaces, Lines, and Points geometry types
✅ Why Surfaces is on by default and what it actually checks
✅ When to turn on Self-Intersect for internal clashes like Duct vs Duct
✅ How to use "Use Current Selection" and "Select in Scene" to speed up setup
✅ Real BIM examples: pipes, ducts, walls, columns, and point clouds
KEY POINT ABOUT SURFACES:
When Surfaces is ON, Navisworks checks the actual solid faces/meshes of your model. If a duct face penetrates a beam face, it’s flagged as a clash. Turn it off and only check Lines, and Navisworks will ignore all solids and only check centerlines.
WHO THIS IS FOR:
BIM Coordinators, VDC Engineers, MEP Modelers, and anyone doing coordination in Navisworks Manage 2024, 2025, 2026.
