A much-requested command from customers has been to provide a tool that converts a 2D polyline into a 3D polyline, by draping it onto a surface.
This is useful for draping design elements to represent controls such as limit of works, matching to existing features and to provide 3D information for further design.
If you are looking for a tool to set objects to adopt surface elevations, check out Drape Objects. This command allows you to select the following objects and set the elevations of these to match the surface:
- Polylines
- Lines and arcs
- Text
- CAD Points, and
- Blocks
The command is simple. After selecting the surface you then can pick a layer containing the objects you want or else pick and choose from the drawing. Next, you pick whether to modify the selected objects or create new objects.

You have the option of making copies of the objects or replacing/modifying them.
For polylines, vertices are added to exactly match the surface elevations including all grade breaks.

The Survey String Settings command is key to controlling how your Point Codes are used in the creation of breaklines, addition of offsets and the creation of 2D and 3D linework.
Stringer Topo V24.20 has been released to support the BricsCAD V24 (as well as current releases of Autodesk software), including a number of new and improved features.
