Removing triangles

Use the Remove Triangles tool (prepare > Post-Processing Tools > Tri-mesh Tools > Removal > Remove Triangles) to remove triangles from tri-meshes based on different tri-mesh properties. You can also remove patches and trim tri-meshes using the other removal tools.

To use the tool:

1. Select a model and the surfaces you want to work on. A list of the available tri-meshes in the model is displayed. Select the tri-meshes to modify by checking the individual check boxes, or by right-clicking the list and making a selection from the context menu.

2. Check the criteria to use to select which triangles must be removed from the following options:

   Delta TVDSS  All triangles with a TVDSS difference larger than the specified value will be removed (Delta TVDSS = the maximum height difference between any two nodes of a triangle).

   Dip  All triangles with a dip property value larger than the specified dip value will be removed.

   Smoothness  All triangles with a smoothness property value larger than the specified smoothness value will be removed.

   Edge length  All triangles that contain a triangle edge which is longer than the specified value will be removed.

3. Click OK to remove the triangles that meet the selected criteria.
