Clip Inside is a surface item modification tool. You might be interested in removing a specific area from a surface. Virtual Surveyor allows you to do this by clipping triangles within a selected boundary. It creates a hole in the surface item where no contour is generated.

The Clip Inside button appears in the SELECTION TOOLS tab and works only if both a surface AND a boundary are selected. 

Quick Guide

  1. Select the surface AND the boundary (hold Ctrl on your keyboard when clicking the items).
  2. Go to the SELECTION TOOLS tab.
  3. Click on Clip Inside button.
  4. The triangles inside the boundary are removed from the surface. The triangles crossed by the boundary are cut out to fit for the boundary.


  • Use Clip Inside to create holes in the surface item and avoid drawing contours within building or water bodies.

Tips and Tricks

  • The elevation of the clipped surface is exactly the same as the elevation of the original surface. The elevations of the boundary vertices are not incorporated in the surface item.
  • After clipping, the internal part of the original surface is deleted once for all.
  • It is possible to clip multiple boundaries inside a surface at the same time by selecting all the boundaries and the surface.
