Offset Wire

Creates (on clicking Offset) a parallel curve, offset normal to the selected curve by the specified Distance.

Note:
If the offset curve is on the wrong side repeat the operation but negate the Distance.

When offsetting segments of a curve, gaps may result at corner points. How these gaps are treated is controlled by specifying the Gap type, with one of the following options:

Natural

Extends each offset segment with an arc equal to the second derivative at the end of the segment until it meets the equivalent arc of the other segment.

Extend

Extends each offset segment with a straight line at the end slope of the segment until it meets the equivalent straight line of the other segment.

Round -

Fills the gap with an arc with a radius equal to the offset value.

Where offset segments intersect, the segments are truncated at the intersection point.

Note:
Offset segments may disappear due to the intersection of other offset segments.
