Follow the steps below when using the Surfaces>General Curve function. Note that to use General Curve Surface, a previously defined set of cross sectional curves must exist. These curves can consist of lines, arcs, circles, conics, or 3D splines. There may be only one curve per cross section. Use the Chain Select option to allow chains of curves to be used as one curve.

 

Using the Function:

1. Select General Curve Interpolation from the Create>Surfaces submenu.

2. Specify the settings through the General Curve Surface dialog that appears when the function is selected.

3. Select the curves and select either ENTER or ACCEPT/OK.
