|Introduced in version|
|Draft Wire, Draft BSpline|
Converting a Draft Wire to a Draft BSpline, and a closed Draft BSpline to a closed Draft Wire
- Select a Draft Wire or a Draft BSpline.
- There are several ways to invoke the command:
- A new object is created.
- The command may result in a closed, self-intersecting Draft Wire or Draft BSpline with a face. Such an object will not display properly in the 3D view. Its DataMake Face property, or its DataClosed property, must be set to
