Hi, Blastpod here. I'm looking for some help on a very important issue. I need to find an app that can create a cylindrical 3D model using a grayscale image, and most importantly one that will allow editing of said model. This is because I am working on making a Maze Bolt. For those of you who don't know, a maze bolt is a cylindrical key inserted into a negative to unlock something. I have my maze designed and ready, but it's in a 2D format. I need to design a 3D maze to operate the bolt lock on a custom machine. See the problem? Help is appreciated. I will provide any knowledge I can that will help the cause, but will not disclose the maze image itself as this could be replicated and make the machine be less of a family secret.
