Already posted in the Grasshopper forum: Taper and undo taper creates barrel distortion
Didn’t get a reply so far, and anyhow this seems to be an issue related to Rhino rather than something specific to Grasshopper. So:
Can I revert a taper to get back to the original object?
The goal is to create an offset that fades in y-direction. For that I tapered the object, then applied the offset, and tried to revert the taper. Unfortunately, the reversion introduces a barrel distortion:
taper.3dm (58.8 KB)
I tried taper with and without the option infinite, and in both cases I get a distortion when trying to revert.
