Traceable
|
When toggled, the curve is flagged as a traceable element on the object tree. In order for the curve to be visible in the 3D view, the Traceable flag must be True and the Draw flag on the Visualization tab of the curve dialog must also be True.

Reverse meaning of start and end points
|
This read only parameter indicates whether the sense of the curve has been reversed internally. In other words, if a curve is defined in the dialog as starting at point p0 = (x0,y0,z0) and ending at point p1 = (x1,y1,z1), the sense of the curve is that it goes from p0 to p1 along the length of the curve when the "Reverse meaning of start and end points" toggle is unchecked. When this parameter is checked, the sense of the curve is that it goes from p1 to p0. Reversal of a curve's "sense" impacts how curves are continuously linked together when used in the construction of a Composite Curve. The composite curve dialog contains a toggle to quickly reverse the sense of an individual curve in order to align the start and end points of adjacent curves. Only a composite curve can control the state of the "Reverse meaning of start and end points" toggle.

Curve Parameters
|
|
Type
|
Type of curve. Options are:
•Circular Arc
•Composite Curve (multiple connected curves)
•Conic arc (defined by coefficients of quadratic equation)
•Line segment (defined by start and end points)
•NURB (Non-Uniform Rational B-Spline)
•Racetrack curve (rectangle with rounded corners)
•Spline (polynomial segments)
•Segmented (points connected by line segments)
•Aperture curve collection (uses closed curves only)
