Quickly switch polylines between 2D and 3D formats directly in your drawing environment with ease and flexibility. The tool maintains accuracy and consistency throughout the process, intelligently retaining essential properties such as layer or color of the original polylines whenever feasible.
Available for AutoCAD, BricsCAD, ZWCAD and GstarCAD.
Difference between polyline types in DWG:
- Polyline: Also known as Lightweight Polyline, a modern 2D polyline that supports lines, arcs, and variable widths, stored efficiently in the drawing. Vertices do not have Z values, but the entire polyline can have an elevation.
- 2D Polyline: An older, heavier type of polyline kept for compatibility with legacy drawings. Vertices do not have Z values, but the entire polyline can have an elevation.
- 3D Polyline: A polyline made of straight segments in three-dimensional space, without arcs or widths. Vertices include Z values, and the entire polyline cannot have a separate elevation defined.
Run the SPMCONVERTPOLYLINE command to convert polylines between types. Most compatible CAD properties (layer, color, etc.) will be maintained.
1. Convert to 2D Polyline
- From Polyline: the elevation value will be maintained.
- From 3D Polyline: the Z values in the vertices will be deleted.
2. Convert to 3D Polyline
- From Polyline: the elevation will be converted to Z values in the vertices.
- From 2D Polyline: the elevation will be converted to Z values in the vertices.
3. Convert to Polyline
- From 2D Polyline: the elevation value will be maintained.
- From 3D Polyline: the Z values in the vertices will be deleted.
Note: Some features are available only in the Standard or Professional editions.
