Improvements to Drop Curve in Style
Drop Curve is improved.
User Interface Location: Click Model > Style > Drop Curve.
Release: Creo Parametric 4.0
Benefits and Description
You can watch a video that demonstrates this capability.
You can drop a curve normal to a surface using the new direction option, Normal to surface and then select the surface on which to drop the curve. You can also drop a curve onto a datum plane in a similar way to that of the Project feature. The dropped curve on the datum plan converts the curve to a planar curve. When dropping a curve on a surface, you can flip the direction. These enhancements reduce the need to create additional geometry and make it easier to define shapes and project them.
