About Multiple Curve Edits

You can edit multiple curves simultaneously using the Curve Edit tab. You can drag points or curves in the graphics window, or specify exact placement or measurement values. Perform the following operations on multiple curves:

Edit Type	Operations
Moving points and curves	Move multiple points or drag tangents on one curve
	Move one point or tangent on multiple curves
	Move multiple points or tangents on multiple curves
	Offset multiple planar curves
Adjusting tangents	Change tangent type
	Change the length, angle, or elevation of one or more tangents
	Change one or more draft angles
	Set length type to fixed or relax
	Add G1 - Surface Tangent, G2 - Surface Curvature, G3 - Surface Acceleration, or Draft Tangent constraints
Changing curve type or reference	Convert planar curves to free curves and vice versa
	Convert COS curves to free curves
	Change references for planar curves
