Description

Projects the boundary of the selected DTM, or selected triangles representing a DTM, to a specified plane, at an angle perpendicular to that plane.

The input DTM data should have no overlaps in the direction of projection as this will result in crossing faces. These will be reported in the Output control bar.

Note: This command supports flexible wireframe selection.

How to Use

  1. Run the command. The Project To Plane dialog will open.

  2. Select the wireframe object using either the drop down or the picking tool.

  3. Define the plane to which the wireframe object will be projected using one of the following methods:

    1. Click one of the standard plane orientation buttons (Horizontal, North-South and East-West) which will set the corresponding Azimuth and Inclination angles. Define where the plane will be in space by setting a Plane Reference Point (e.g. adjust the Z: value to the level where you wish a horizontal plane to split the selected wireframe object. The plane is logically infinite so the X and Y values are irrelevant in this case.)

    2. Set the orientation manually by editing the Azimuth and Inclination values, then fix the plane in space by setting a Plane Reference Point.

    3. Use the View Plane.

    4. Use the Pick Face tool to select the face of an object to be used to split the wireframe.

  4. Choose whether the projected end of the wireframe should be capped at the intersection with the specified plane.

  5. Click OK to run the operation.
