Fitting a curve to selected points
This command creates a point cur ve fitted to
points you select. The points can be part of
previously created point curve and point surface
objects, or they can be poin t sub-objects you
created explicitly. They c an’t be CVs.
Procedure
To create a point curve with Curve Fit:
1.
Turn on Cur ve Fit.
2. Click to select two or more points.

When you use Move to create the transform
cur ve, it simply copies the parent. (It doesn’t
exaggerate curvature as an offset curve does.)
Axis constraints don’t apply to the creation of
transform curves. You can click to create the
