SURFEXTRACTCURVE

Creates curves on surfaces and 3D solids.

Access Methods

 Toolbar: Modeling tool set Open Shapes tool group (expanded) Extract Isolines

 Menu: Modify 3D Operations Extract Isolines

Summary

Creates curves, typically in the U and V directions, on a surface, a 3D solid, or a face on a 3D solid.

The curves can be a lines, polylines, arcs, or splines based depending on the shape of the surface or 3D solid.

List of Prompts

The following prompts are displayed.

Select a Surface, Solid, or Face

Select a surface, 3D solid, or face of a 3D solid.

Select point on surface or [Chain/Direction/Spline points]

Click to extract curves, or choose an option. By default, isoline curves in the U direction are selected.

Chain

Displays isolines across adjacent faces if the faces are parameterized in the same direction.

Direction

Change the tracking direction (U or V) of isoline curve extraction.

Spline Points

Dynamically tracks in both U and V directions to create a spline that passes through all specified points on the surface.
