How
to create a high-quality NURBS curve from scan data.
Section data in reference
layers can be selected from within this tool.
Fit a NURBS curve to
a scan line
- Choose Curve Edit > Fit Curve
.
The control window
opens automatically.
- Click the scan line (section data).
A NURBS curve is fit
to the section data.
- Do any of the following:
- Drag the start and end point manipulator
arrows to control which part of the scan line the curve is fit to.
Usually you will want to fit curves to sections with little curvature.
- Turn on the Curvature option
to show a curvature comb plot on the new curve.
- Turn on the Deviation option
to show the maximum deviation between the new curve and the scan
line.
- Adjust the Degree and Spans settings
in the Fit Curve control window to
try to achieve a better fit. Increasing these values will make the
curve fit the scan line better, but will also give you a more complex
curve.
NoteThe new NURBS curve
has construction history.
