Is it possible to mimic the way Civil3D colors the path while selecting, using a jig? And if so, does it not use a lot of resources to continuously calculate a part of a polyline while moving around?
In Civil3D, for example, if you split a Parcel, you can select the path along a Parcel line and while dragging the mouse, you see a colored line along the Parcel lines from the first selected point to the place where the cursor is, untill you click.
I know it is possible to split a polyline with Curve.GetSplitCurves() but is that the way to get a part of the polyline and show it as a jig? Or are there smarter functions to do this?
