Hi Folks,
Sorry if this has been asked before but I have searched the forums and can't anything to do with this. Also please correct me if I am posting in the wrong forum.
I am making an application with functionality similar to a revolution of a sketch within any CAD program.
I don't really have a mechanical engineering background (took a solidworks and pro|e class once), and I feel like I jumped the gun by making Bezier Curves the primary basis for these sketches that can be extruded and revolved.
My question is:
Are Freeform cubic bezier curves even used within this industry? Are there any examples of programs that have definable values to position control points? For example, pretend a curve represents an aspheric surface of a lens, and the user would like to control the distance between the two end points and the curvature with parameters (but in my application the user only has control of the 4 control points of a cubic bezier curve). Also maybe a user draws an ellipse to be extruded but needs to manipulate the major and minor radii programatically. Are there any programs with similar behaviors? Am I going about this completely wrong?
Thanks
