Project to Elevation

On the Design tab, in the Editing group: Click Project to Elevation to project a string based on the elevation, slope, and (in or out) direction you specify. If no strings are selected when you click this tool, the Selection Assistant will prompt you to select the string or strings you want to project.

This tool differs from the Project to Elevation tool on the Pit Design toolbar, which projects a pit string based on existing pit parameters and a specified elevation.

Drape onto surface

When this check box is selected, the selected string is projected to the defined elevation and is draped onto the selected surface.

Clean resulting strings

Select this check box to remove any unwanted object artefacts which may appear if the projection angle correlates closely with the slopes on an undulating surface DTM.

The following example shows a scenario where the surface contains steeply dipping sections. The highlighted (blue) string is the selected string that is projected. The red string is the resultant string when the drape option was enabled:

The selected string is projected to the defined elevation. To understand the resultant string, imagine a wireframe being produced using the input string and the projected string. The intersection between the wireframe and the surface is used to derive the resultant string:

Note: The Drape onto surface option may produce unexpected results if the surface contains steeply dipping sections that are similar to the slope value specified in the form.
