The Merge command can be used to join or combine selected components, depending on the context.

If two vertices are selected, the first will be moved to the position of the second and they will be merged to create a single vertex.

If more than two vertices are selected, then any selected vertices which are closer together than the Vertex Tolerance will be merged with one another. This tolerance can be set in the Merge Options. This is particularly useful if you have separate pieces of geometry whose vertices are aligned and you want to join them together.

If faces or edges are selected, each face or edge will be collapsed into a single vertex, as if all the vertices of that face or edge had been merged together. For instance, you can select an Edge Ring and use Merge to turn it into an Edge Loop.

If multiple objects are selected, these objects will be combined into a single object. No geometry changes will occur. (For example, no vertices will be merged even if they are overlapping.) This is the same as the Combine Objects command.


Vertex Tolerance

When more than two vertices are selected, selected vertices which are closer together than this value will be merged when Merge is called. If only two vertices are selected, they will always be merged regardless of the tolerance.

Also Known As

The behavior with edges and faces is also known as Collapse in other applications.


  • The merge tolerance must be changed before rather than after performing the merge operation in order for the change to have an effect.
  • Faces collapsed in a Merge command will be removed from the object.
