Combine polygon meshes

User Guide > Modeling > Polygonal Modeling > Combining, separating, and splitting > Combine and separate polygon meshes >

You can combine two or more polygon meshes into one polygon object using the Combine feature. The Combine feature assembles the meshes as polygon shells in a new polygon mesh node that gets created. The topology of the combined meshes are not modified in any other way.

In general, you must combine separate polygon meshes before you can perform many types of polygon editing operations. For example, if you wanted to merge the edges/vertices of two halves of a character, you must first Combine the meshes into one object.

To combine two or more polygon meshes into one mesh

Select the meshes you want to combine into a single object.
Select Mesh > Combine.
The meshes are combined as separate polygon shells in one new polygon mesh node.

Notes

Combining meshes can result in non-manifold geometry, where the normals of adjacent faces are pointing in opposite directions. To avoid this, use Normals > Conform to flip all normals in the combined mesh to the same side.
