Trimming surfaces by a polygon

Use the Trim Surfaces by Polygon tool to modify polyline sets by removing all nodes inside or outside a polygon. Other removal options related to handling large segments or single nodes are available as well.

You can verify whether a polyline is closed via the Polyline form (right-mouse click on a polyline set in the JewelExplorer or in a view and select Edit... ). On the form a checkbox next to the polyline's Id marks whether it is closed, or not.
  1. At the top of the form, select a source from the 'Source' drop-down list. This selection populates the table below.
  2. From the list of the available polyline sets in the model, select the polyline set(s) to modify by checking the individual check boxes.
  3. Select the polygon to use for trimming from the Polygon for Trimming drop-down list.
  4. Under Remove Section, choose between removing the nodes inside or outside of the selected polygon.
  5. Click OK to remove all the nodes which are inside or outside the polygon.
