PolyHertz has released UnChamfer Pro, a script designed to allow for quick, easy, and accurate removal or scaling of mesh chamfers. All the user has to do is select the edges of the chamfer they want to be removed and run the script.
The script supports both Editable Poly & Edit Poly modifiers. And works with 3ds Max 2013 – 2022. You can buy the script just for $8 on Gumroad.
