About Curve Operations

Import DataDoctor > Geometry Modification Tools > Modifying Surface Boundaries and Curves > About Curve Operations

Curve operations in IDD apply to the following objects:

• 3D splines

• UV-splines

The commands to perform curve operations are available on the Edit tab in Import DataDoctor and are as follows:

• Modify shape (

Modify)—You can modify the shape of a curve by tweaking its control polygon or by modifying its interpolation points.

• Merge contiguous curves (

Merge Curves)—You can merge two or more contiguous curves into a single curve.

• Split a curve (

Split Curve)—You can split a curve into two by selecting a point on the curve.

• Delete curves—You can select a curve in the graphics window or on the GTS Tree and delete it. When you delete a 3D curve or a UV-curve, the curve and all constraints associated with the curve are deleted.

• Align curves (

Align)—You can use the align tool to create new constraints for a curve.
