Ditch allows you to create V shaped ditch on the surface model.
Ditches read AutoCAD polylines, lines, arcs, circles, ellipses and splines. Ditch is a V shaped geometry cut into the surface model along the polyline.

Parameters
Layer - Layer where ditch polylines or lines are.
Materials - Material of the ditch.
Description - A descriptive text for the entry. If defined, will be shown instead of the long description.
Info text - Information text attached to items.
Info URL - URL link attached to items. MAGNET Explorer can launch a Web browser with the URL.
Object data tables - Autodesk Map object data tables that will be used for source of object information for the elements in the virtual model. The table list also matches wildcards.
Width - Width of the ditch in drawing units.
Depth - Depth of the ditch in drawing units.
Target_layers - These material area settings affect only to surface on layers defined here. The default value (*) means that all surfaces are affected.
Group - The name of the group of these items.
Auto_segmentation_distance - Divides the original polyline with this distance and adds new points. This parameter is useful for better control of follow surface and long arc segments.
Auto_segmentation_angle - Divides polylines using angle threshold so that resulting polyline will fall within this angle value. This has only effect for curved polyline segments like splines and arcs.
