Inquire Curve Curvature Plot (3D/2D)
Inquire 
Curve (Part/Sketch/Sheet/CAM
Level)
Use this command to display the curvature plot of curves
or edges. The plot is displayed as line segments projecting out perpendicular
from the curves. The length of each line segment illustrates curvature
at that point on the curve. This command helps to visualize overall curvature
across a curve or edge.
As each new curve is selected, a new scaling factor is computed
and applied to all selected curves. The curvature plot is only temporary.
It remains displayed while curves/edges are selected even if you pan,
zoom, or rotate. Once you signal that you are done selecting curves/edges
(middle-click), the plot is removed when the display is redrawn or altered.
The curvature plot displays an X at the end of the first
and last tooth of each curve. Otherwise selecting two curves with a tangent
join would only show one tooth (the larger one) since one overwrites the
other. If there are two X's visible at a join, you know they are discontinuous
at that point. You
can apply this command from the active part to another component in an
assembly or sub-assembly.
Curves
Select curves or edges to plot. Dynamically view the curve as desired and middle-click to continue. The curvature plot will be removed automatically when the display is altered.
Scale
Use this option to set the scale factor. Adjusting
the slider bar will dynamically alter the length of the comb teeth. The
slider is centered at zero. Moving the slider to the right makes the curvature
lines longer (up to 5X) and moving to the left makes them shrink (down
to 1/5 X).
Move the slider bar to set the desired scale factor.
Sample
Use this option to set the number of comb teeth to display.
Enter the number of comb teeth between 20 and 500. The default value is 100.
Draw comb toward outside
Check this box to direct the curvature plot outward as illustrated
below.
Data
Use this option to set the type of vector field displayed. The default displays the curvature vectors. You can also examine 1st, 2nd, and 3rd derivative fields of the selected curves.
