Offset Along Faces : Options and Results

Offset a curve along 3D faces (or mesh) so that the offset value is kept along the selected faces.

This is useful for parting surface splitting at a certain distance from the parting line, as well as for similar operations in die design.

Required Step 1

1. Pick the reference object (B-rep or mesh) along which the curve is to be offset.

   Reference object	Object selected (colored GREEN)

Required Step 2

1. Pick the curve to be offset and set the parameters.

2. Pick a wire or curve/edge lying on the selected object and set the parameters. This curve will be offset along the reference object selected in step 1.

   Parameters

   Global Offset	Set the distance the new geometry is to be offset from the reference geometry. Default = 10 mm (0.5 inch). The offset geometry lies on the reference object faces, where the distance is measured along the faces. ExamplesExamples
   Flip	Toggle option to flip the resulting geometry to either side of the reference geometry. The default offset side is outside for a closed reference contour and according to the curve direction for an open reference contour. ExamplesExamples Offset result Offset result flipped side
   Keep Original	Toggle option to either keep or remove the original geometry.

   Note: Partial results may be obtained in some cases, for example, if the resulting geometry has intersecting curves.
