Cutting polylines

Use the Cutting tool in the Structure Builder to cut polylines at tri-mesh intersections based on a specified gap size, dip, and smoothness level.

Other means of handling polyline-tri-mesh intersections are available in the Structure Builder group.

1. Select a surface set or seismic interpretation.
2. Click Calculate. This will populate the table on the form with all the polyline sets and tri-meshes that are intersecting.
3. Select the polyline set -tri-mesh intersection you want to modify. You can click the individual check boxes or right-click the list and make a selection from the context menu.

4. Specify the cutting settings or accept the ones listed in this step. You can change, select or deselect the following values:

   Gap size  Define the size of the gap that is created.

   Dip  When you specify a dip value, only nodes with a dip property value larger than this will be removed.

   Smoothness  When you specify a smoothness value, only nodes with a smoothness property larger than this will be removed.

   Re-triangulate modified polyline sets  Automatically re-triangulate the tri-meshes that are adjusted by the cutting process (recommended).

   Recalculate intersections  Automatically recalculate the polyline-tri-mesh intersections after the cutting process (recommended).

5. Click OK or Apply to perform the cutting process.
