Splined Circles


SEANT

Recommended Posts

Here is a routine that may be of some interest, though not one to which I can assign much practical value. Mostly it is just a follow-up to an imprecise posting I made here.

Posting the code may have some value due to the relative scarcity of AutoCAD .NET examples in general.

 

If anyone cares to give it a test drive:

 

Command: Netload CsSplineCircle.dll

Command: scirc

 

As always, comments and criticisms are welcome.

These splined (Nurbs) circles may have some application in cam development. If a correct profile is available via “Weight” modification, it would be very efficient computationally, and with memory, compared to a typical piecewise curve description.
