Inquire Curve Parameter Space (3D)

Inquire > Curve (Part/CAM Level)

Use this command to display the parameter space of a curve.  Point markers at each point on a curve associate with a knot value are displayed along with the normalized parameter and arc length values at each point.

This helps you determine how close the curve is to arc length parameterization.  This echo relates to the existing curve.  Use the Cubic Refit Curves command to echo this information for a resulting refitted curve.  You can apply this command from the active part to another component in an assembly or sub-assembly.
 

Parameter Space Partition of Curve
 

Example:
 

Distinct knots of curve: { -0.25, 0, .33, 2.0 }
Arc length to each knot: { 0, 5.0, 10.0, 50.0 }
 

Displayed along curve:

t=0.00,len=0.00
t=0.11,len=0.10
t=0.26,len=0.20
t=1.00,len=1.00
