I want to make a request for the output of extrudecrvtapered to be improved. A better result can almost instantly be achieved, after running the command, duplicating the edge of the result, and performing a sweep2 with the original curve to be tapered as a second rail. Using just a straight cross section, refitting rails so as to not get polysurfaces where surfaces may be sufficient at breakpoints and so on.
Is there a you track or anything that I can add a vote to? Just to try and do away with the triangular surfaces that you get as standard with this tool at break points.
