Curves are paths in 2D or 3D space from which you can create surfaces, solids, and features. You can create them in FeatureCAM or import them from a CAD system. Curves are displayed in blue, for example:
Curves can be open or closed. Open curves have end points that do not meet. Some features must be created from a closed curve. A closed curve defines an area that is separate from the exterior of the curve.
Warning: Any ambiguities such as overlapping or intersecting curve links can cause failures and unpredictable results in the machining routines in
FeatureCAM.
