Parallel to Multiple Curves
Introduction
The Parallel to Multiple Curves feature creates a toolpath as an offset of a leading curve. The neighboring toolpath segments are parallel to each other. An important point here is that the cuts are not simply copied next to each other; every new cut is an offset of the previous cut. When selecting the curve geometry, select the curves directly from the part. When using a single drive surface, you can only select one curve from which to create a parallel toolpath. When using multiple drive surfaces, you can then select multiple curves to use. Each curve is only used for the drive surface nearest to that curve.

-
Edge Curves - enables selection mode for you to select the lead Edge curve geometry.
-
Drive surfaces - enables selection mode for you to select the Drive Surfaces geometry. The toolpath is applied to the selected surfaces.
-
Drive surfaces offset - is used to leave stock remaining on the part. You can type positive or negative values.

How it Works
-
The toolpath segments are offset parallel to the curve (red), not copied.
-
When the curve has arcs or similar shapes, at some point the cuts must interleave. Where the arcs collapse sharp corners are generated.
-
If the curve doesn't cover the whole surface edge, the cuts end in an arc.
Note:
• The curve must be located exactly
on the surface edge. If you don't have a proper leading curve aligned
to the edge, an incorrect toolpath can be generated.
• If you select multiple curves, only
the first curve will be used. For more complex models it is difficult
to provide the correct leading curve to machine the whole model.
• You can define a margin to get the exact
position where the tool is located at the edge with a certain distance.
• It is possible to use multiple curves
for multiple surfaces. Each curve is used only for the nearest surface.
Example
-
The curve (1) is the leading geometry. All cuts (2) are being creates parallel to the curve.
-
The animation shows the pattern. Note that the toolpath starts at the opposite side of the curve.
