General Usage Instructions

Select an AutoCAD Solid that cut or pass through a Civil 3D TIN Surface.

select this surface, specify the name of the new surface that will be created on the bottom of the solid. If the name of the TIN Surface to create already exists, this command will erase all points of the surface and add the newly generated points.

The number of points per AutoCAD unit of the drawing represents the number of points will be added to the new surface along the edge length, higher values result in more dense TIN surfaces.

Additional Information

Known Issues

Users of Civil 3D may encounter problems with points at the same elevation, or drastic changes of elevation (e.g., the plane of the surface changing).

In these situations, the generated surface is less accurate in these areas. Users can manually add break lines to adjust the behavior.

High-density values can cause the application to hang due to the large volume of points generated. For these situations, users should consider starting with small values to obtain initial surfaces.
