offsetCurve

Go to: Related nodes. Attributes.

Create a new curve which is an offset of an existing curve. The 'distance' attribute defines how far the offset curve should be from the original curve, and the 'tolerance' attribute sets the accuracy required. 'subdivisionDensity' defines how many times the offset curve spans can be subdivided in order to match the required tolerance. If there are sharp corners on the original curve, the offset curve may break into separate sections at these points. The attribute 'connectBreaks' can be set to ensure such breaks are filled, either with a linear or a circular curve section. In some cases the offset curve may contain a loop. The attribute 'cutLoop' can be set to cut off such loops, and, if this attribute is set, an additional attribute 'cutRadius' can be set to round off the resulting corner. 'useGivenNormal' defines whether a user-defined normal is or the normal to the curve is used.
