Interference¶

Interference finds bodies that overlap, which you want to know before you print an assembly. It needs at least two bodies.

1. Under Inspect, open Analyze and pick Interference.
2. Each row names a pair of bodies and the volume of their overlap, and the overlap is drawn in red in the view.
3. Click a row to highlight that pair.

An overlap inside a part is hidden, so press X to see through the parts.

Turn on Clearance mode to also list pairs that come closer than a gap you type. It starts at 0.2 mm, a common gap for parts printed in place.

Only closed solids can be checked. A surface, or an import whose faces do not close, is listed as Not checked with the reason, so an empty list never hides it.
