Plan View Boundaries

Source file: creating-2d-outlines.htm

Use the Plan View Boundaries tool to project the outline of the tunnel onto a horizontal plane.

To create an outline, click on the Plan View Boundaries button on the Underground ribbon tab, then follow the steps below.

Note:  Parameters are explained in mouse-over tool tips.

1. Select the relevant tunnel point clouds or hull surfaces in the project explorer or active view window.

2. Enter the plane's height by either typing in the Projection height field or clicking a point at the required level in the view window.

   Tip:  You can use the action plane and snap modes to help with this.

3. Set the distance and length parameters according to requirements:

   • Isolated point distance: Points will be excluded if they are farther than this distance from any neighbouring points. Increase this value to include more points.

   • Maximum triangle length: Triangles with longer edges than this value are excluded from calculations. Increase this value if no boundary is made or the process takes too long.

   • Minimum boundary length: Produces a smoother outline and removes small “islands” from the result.

4. Click OK or Apply.

A new edge network object named Boundaries <number> will be created and nested in the cad container.
