View Full Version : "Polygonal" rail extrude? // w/o adding a slew of points in the corners

As in "Polygonal Lasso":

Is there a way to Rail Extrude that will extrude only in straight sections with 'hard' corners? A normal "rail" might be very soft in the corners.

An example: Imagine adding the kickplate moulding around the bottom of an octagonal room. Not all of the corners will be 90, but they will all be 'hard'. Plus, the moulding might extend down a hall or thru a short doorway. (Just examples.)

What I'd like to avoid is manually adding a bunch of points in corners merely to restrict the Rail.

Perhaps a "Polygonal RAIL" is what's needed, that doesn't require any more points than the spliney ones.

Would LWCad Engraver work, I use it for skirting & cornice.

Px_Bezier (https://www.lightwave3d.com/assets/plugins/contains/px%20bezier/)
Just don't pull out the bez handles.
(edit:.... or just set Segments to 1. Which is probably more to the point.)

not what you are looking for in terms of extruding along a rail, but pz bezier would let you extend anyway you want.and straight corners etc, if you make a curve from px bezier ..you could save out as path..then reload later when needed and use for extend etc.
px bezier costs nothing.
