How to obtain a small offset around a polyline? (AutoCAD .net API)

Offsets from a panel are used extensively in detailing.

Here’s how to do it – simple, no? See below:

DBObjectCollection _offsetPolylines = polylineInstance.GetOffsetCurves(25);
     // offsets the polyline by 25 mm
     // the object collection should really have only one item in it: a polyline offseting the original by 25mm.
