In this video, I demonstrate how to quickly model a window using lines in 3ds Max. The key feature here is the Boolean function within the line tool, which allows you to trim intersecting or protruding lines with ease. Starting with a rounded window frame and overlapping muntins, I use the Boolean tool to cut and clean up the geometry. This leaves us with a perfectly trimmed window shape. I then apply the Shell modifier to give it height, revealing the final 3D model. A simple and effective technique for clean window modeling!
