Reduce the number of triangles

Use the Reduce option to reduce the number of triangles in the model:

1. Select a mesh.
2. Click Mesh Tools tab > Triangles panel > Reduce to display the Reduce Mesh dialog:

   

3. Specify the reduction parameters using one of the following methods:
   • To percentage of original — Enter the percentage of the original number of triangles to be in the mesh.

     For example, enter 75. The number of triangles in the mesh is reduced by 25%, resulting in a less smooth mesh.

     

   • To number of triangles — Enter the target number of triangles for the resulting mesh.
   • To tolerance — Select this option and enter a tolerance to reduce the number of triangles. Optionally select Limit triangle edge length to specify the maximum edge length of triangles in the reduced mesh.
4. Click Apply to reduce the number of triangles in the mesh. The dialog remains open; you can change the values in the dialog to reduce the number of triangle again.
5. Click Cancel to close the dialog.
