Removing a Local Area

You can select and remove local areas. The removed local areas are those that appear in red during selection.

Before you begin:
  • Remove takes into account triangles that are at least partially selected (at least one vertex has been picked, or the selection trap intersects the triangle).
  • The free edges of the mesh resulting from Remove are its actual free edges, not those of the initial mesh.
  1. Optional: Under App Preferences > 3D Modeling > Multi Discipline Engineering > Terrain Preparation in the General section, select the Undo/Redo for in-place cloud edition commands check box.
  2. Optional: Protect characteristic lines from deletion.
  3. From the Prepare section of the action bar, click Remove a local Area and select the cloud of points or the mesh.
  4. On the context toolbar, define the local areas to be removed.
    1. Click Trap in the context toolbar.
    2. Click Rectangular.
    3. Drag the cursor and click to draw a first rectangular trap on the cloud.
    4. Click to validate the trap.
  5. Repeat step 2 to draw as many traps as required.
  6. Optional: Click Select all to select all the points or Swap to invert the selection.

    Warning: Select all and Swap apply only to the current action.

The triangles that were inside the traps are removed.

Important: Removed points are deleted and cannot be recalled.
