Creates quality curves by fitting to cross-section line data, curves-on-surface, trim edges, isoparms (including surface edges and patch precision lines), and other free curves.
Enter a name for the new curve.
Turn on this option to show a curvature comb locator on the new curve. This option is off by default.
You can change the comb scale and other settings through the Curvature tool in the Control Panel.
Show a maximum deviation locator between the new and original curves. This option is on by default.
Set the degree of the new curve. Increasing the degree allows a better fit, however not all CAD systems support curve degrees higher than 3 (which is the default).
Set the number of spans in the new curve. Increasing the number of spans gives a better fit, but also increases the complexity of the model. The default is 1.
Save the fit curve history for further editing.
When the option is not selected, template curves are not kept when fitting to cross sections, so you do not have to delete them after leaving the tool.
This option is only available when fitting a single curve to a curve-on-surface.
If it is checked on, a warning appears, saying that the target curve-on-surface might be modified, and its construction history deleted.
If you choose to proceed, the fitted-curve is projected onto the surface to create a new curve-on-surface. The fitting operation is repeated with the new curve-on-surface as the target. This process continues until a solution (within tolerance - see below) is found.
This slider controls the maximum lateral distance that the curve-on-surface (the target) is allowed to move when Modify target is turned on.
Clicking this button removes all the fit curve segments on the current target curve. It also restores the original curve-on-surface if it was previously modified by Modify target, but does not restore its construction history.
