Project to Surface

Source file: project-to-surface.htm

Use the project to surface tool to project lines and polygons (in the 2D plane) onto a topographic surface. This can be useful if, for example, you are creating a topographic surface and want to use the Split surface along edge constraints option.

1. On the Edit ribbon tab, go to the Project group and select Project to Surface.

   
   

2. Select the Target surface for the lines and or polygons.

3. Select the lines and/or polygons to project.

4. Select the Crop to surface boundary to trim the lines at the surface's boundary or scale polygons to fit the outer edge of the surface.

5. Select Project a copy to leave the original points in place, and create copies projected to the edge. Clear this option if the points are to be moved.

6. Click OK or Apply. The line or polygon will be draped to the selected surface.
