About Moving and Copying Style Curves
Move, 
Copy Curve, and 
Copy Proportional apply only to Style curves. These functionalities apply to planar and free curves, circles and arcs, but not COSs.For planar curves, the planar constraints are not violated.
• Move allows you to translate, rotate, and scale the Style curves.
Move allows you to translate, rotate, and scale the Style curves.• Copy Curve duplicates the selected curves and allows you to translate, rotate, and scale them. Soft points are preserved during a copy. The copy may be unlinked, in which case references to the curves being copied are unlinked, if necessary.
Copy Curve duplicates the selected curves and allows you to translate, rotate, and scale them. Soft points are preserved during a copy. The copy may be unlinked, in which case references to the curves being copied are unlinked, if necessary.• Copy Proportional duplicates the selected curves, while retaining the original proportions when the endpoints of the first curve in the selected geometry are moved to new positions during duplication.
Copy Proportional duplicates the selected curves, while retaining the original proportions when the endpoints of the first curve in the selected geometry are moved to new positions during duplication.Copied curves do not maintain history with the original curves. However, the copied curves preserve the relationships that exist between the individual curves in the set of curves selected for copying.
Copying Curves with Soft Point Constraint Proportionally
Soft point constraints do not allow you to copy curves proportionally. You must remove the soft point constraints to copy curves proportionally, or copy the constrained curves proportionally along with the parent curves.
 | To remove the soft point constraints, click >  Unlink while copying a curve proportionally. If you do not click > Unlink, the constrained curves are copied proportionally along with the parent curves. |
