As of Vectorworks version 2012, a new type of polyline vertex, the radius vertex, simplifies the reshaping of polylines. Polylines from older versions may include arc vertices, which are harder to edit. Each vertex of a polyline can be changed to radius type with the Change Vertex mode of the Reshape tool, or by editing the vertex type in the Object Info palette. However, this is tedious if the object includes several arc vertices. The Convert Arc to Radius Polyline command is available to convert all of the arc vertices to radius vertices. Objects like hardscapes or slabs (Vectorworks Design Series required), which are based on path polylines, can benefit by converting their path polyline to contain radius vertices, because they become easier to reshape.
To convert arc vertices to radius vertices:
1. Select the polyline; for path-based objects, double-click on the object or select Modify > Edit [Object] to access the path in editing mode. See Object Editing Mode.
2. Right-click (Windows) or Ctrl-click (Mac) on a polyline which contains at least one arc vertex, and select Convert Arc to Radius Polyline from the context menu.
3. The arc vertices of the polyline or path object are converted to radius vertices.
