Merge vertices, edges, or faces into one vertex


You can merge vertices, edges, and faces into a single vertex using the Merge feature. When you merge vertices, coincident edges and their associated UVs are also merged automatically (within a specified threshold).

To merge several vertices into a single vertex

  1. Select the vertices you want to merge.
  2. Select Edit Mesh > Merge > .
  3. Set the Threshold setting to control how close vertices must be to merge.
  4. Click Merge.

    You can only merge edges that are part of the same polygon mesh.

If you want to merge edges from different mesh objects, you must first combine the meshes into a new mesh using Mesh > Combine.

Merge Vertex Tool

You can merge two vertices on the same mesh together using the Merge Vertex Tool. Merging two vertices with this tool yields the same result as selecting the vertices individually and using the Merge feature.

To merge two vertices using the Merge Vertex Tool

  1. Select a mesh.
  2. Set the component selection mask to vertices.
  3. Select Edit Mesh > Merge Vertex Tool.
  4. Drag the mouse from a source vertex on the selected mesh to a destination vertex.

    The vertices merge to become a single vertex.

When dragging between the vertices you want to merge, a red line appears from the source vertex to the mouse cursor.

You can also merge multiple vertices with the Merge Vertex Tool.

To merge multiple vertices

  1. Select a set of vertices with the Select Tool.
  2. Select Edit Mesh > Merge Vertex Tool.
  3. Drag the the mouse from one of the source vertices to a destination vertex.

    All the selected source vertices merge with the destination vertex.

You can change the behavior of the Merge Vertex Tool, with the Tool Settings Editor, to merge the vertices at either the destination vertex or at the center between the source and destination vertices. In the latter case, a small red dot will appear at the center of the red line drawn between the source vertex and the mouse cursor.

You can merge several vertices to their collective center using Edit Mesh > Merge To Center.

To merge edges or faces into a single vertex

  1. Select the edges or faces you want to merge to a center point.
  2. Select Edit Mesh > Merge To Center.

To merge a selection of edges separately

  1. Select the edges you want to merge on a component by component basis.
  2. Select Edit Mesh > Collapse.

    Each edge is collapsed and its component vertices merged.
