Would be nice to have AutoCAD/Revit style spline editing. Some examples:
1. Spline offset that creates a new spline (unconnected) from the selected spline. (similar to the way AutoCad offsets)
2. Multiple spline offset - set the distance and number of copies.
3. When a spline is open and/or self-intersecting, provide a visual cue as to where it is unconnected and/or crossing itself. (I wrote a script to kind of accomplish this, but it would be good to have natively, like the magenta boxes in Revit)
4. Spline offset preview. (Sometimes I need to offset a spline with the slider to get an idea of how far I need it to offset and then type in the actual value I want. Currently, I use the slider do get an idea of the distance, undo, and then type in the exact value I need.)
5. The ability to detect and remove double/overlapping segments.
6. Built-in ability to flatten splines.
...More ideas for this??
