Triangle decimation

The utility Triangles decimation processes triangles of the selected surface and identifies zones with similar slope. The zones are then re-triangulated to reduce the number of triangles.

• Click Surface.

• Click Tools to open the menu.

  

• Click Triangle decimation.

• The command opens a new window.

• It is possible to decimate the triangles in different modes.

• Select Decimate full surface to decimate triangles of a selected surface subproject:

  

  • Surface to decimate: select the surface to process.

  • New surface to create: the name of the resulting surface.

  • Max slope difference: the maximum slope difference between triangles to consider for the decimation.

• Click Decimate to start the processing.

• Select Pick the area to decimate to decimate a selected area:

  

  • Max slope difference: the maximum slope difference between triangles to consider for the decimation.

• Click Pick area to select on CAD the starting triangle for the decimation.

• The software shows in yellow the triangles that will be decimated. Select Yes or No to accept the new triangulation.
