The term "Curve" is used in the program and its documentation in two ways, while the meaning depends on where it is used.
- The term Curve is a general term for objects Line, Polyline, Arc, Circle, and Spline.
- The term Curve can also refer to multiple objects (ad 1/) connected in their boundary points. This second meaning of the term Curve is mainly used in connection with a "Boundary Curve", "Internal Curve", and so on.
There are several rules that need to be followed during the definition of a Curve:
- Curves cannot intersect each other or themselves except at their definition nodes.
- No point that is not either its definition or Parametric Point can lie on a Curve.
- Curves are always defined using their definition points (their indexes). The list of indexes can be checked or changed using the Edit Curve dialog (the first Tab "General").
The following commands are available in the Curves part of the Insert Menu:
