Mesh Intersection

In one sentence: Compute the Boolean intersection of two solid meshes, keeping only the volume where both meshes overlap.

Overview

Workbench: Mesh
Menu: Mesh → Meshes → Boolean → Intersection
Command: Mesh_Intersection
Shortcut: none

Computes the Boolean intersection of two selected meshes — the mesh that represents only the volume where both inputs overlap. If the meshes do not overlap, the result is empty.

Intuition

Mesh Intersection is the mesh equivalent of Part Boolean Common — it keeps only the material shared by both inputs. Use it to find the common volume between two overlapping scan meshes or to compute the portion of a mesh that fits within a bounding region.

When to use it

  • Finding the common volume between two overlapping scan meshes.
  • Clipping a mesh to a bounding region.

When NOT to use it

  • Don't use it on non-overlapping meshes — the result is empty.
  • Don't use it on non-solid meshes — both inputs must be watertight.

Step-by-step

  1. Select the first mesh.
  2. Ctrl+click the second mesh.
  3. Choose Mesh → Meshes → Boolean → Intersection.
  4. A new mesh appears containing only the shared volume.

Common mistakes and pitfalls

Both meshes must be solid

Run Evaluate Solid on both meshes before attempting intersection.

Non-overlapping meshes produce an empty result

Verify that the meshes actually share a volume before running the intersection.
