• Creates a 3D offset of a selected 3D polyline.
• Converts the original 3D polyline into a temporary 2D polyline.
• Applies a user-defined offset distance.
• Reconstructs a new 3D polyline using original Z-coordinates.
• Restores system variables and cleans up temporary entities.

🚀 3DF_to_3DPoly is an AutoCAD and Civil 3D AutoLISP utility that converts selected 3DFACE entities into closed 3D polylines while preserving the original vertex elevations. It helps CAD and Civil 3D users transform face-based geometry into editable 3D polyline boundaries for cleanup, drafting, terrain preparation, and production drawing workflows.

🚀 Convert3DFaceToPolyline is an AutoCAD and Civil 3D AutoLISP tooltip and command description for converting selected 3D Face objects into closed Polyline boundaries. It helps CAD users transform face-based DWG geometry into editable polyline outlines for drawing cleanup, drafting review, and Civil 3D production preparation.
