PTC has improved the Drop Curve feature in Style to allow the new direction option of Normal to Surface and then selecting the surface on which to drop the curve. You can also drop a curve onto a datum plane, in a similar way to 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.
