Hey.
Tom is taking on a simple, but the sometimes troublesome shape and giving you a quick modeling tip. We will be modeling in 3ds Max using a quick and convenient technique that you can use on your end. It will allow you to easily 3d model both convex and concave screws and threads in 3ds Max.
Be sure to let us know in the comments if you found this 3ds Max modeling technique useful!
