Creates a 3D polyline at a desired grade or slope along a tin surface.

Corridor multiple targets (CMT) is an add-in tool for Autodesk® Civil 3D®. This tool attempts to simplify targeting of complex corridors using text filters and using modelspace entity selection.

Morphs one polyline into another by generating intermediate polylines at arbitrary stages of the process.

Move polylines to an elevation value stored in an Object Data field.

This tool allows you to add labels to all contours more easily.

Toggles various surface plan/model view display components from the command line.

The application for modeling curves and surfaces of high quality on criteria of smoothness.

This app helps you save a lot of time to select objects by quickly making filter and quickly selecting similar objects based on sample entities.

The user can place blocks along LINES, LWPOLYLINES and 3DPOLYLINES.

Merge surfaces end-to-end with smooth blending across gaps and transitions; Use SmartPaste to combine surfaces with interior voids.
