I have never tried 3D in Scratch before, but as they say, there's always a first time! This is an attempt to create a 3D shape with a user-defined constant cross-section. To use: simply draw your 2D shape with a continuous line. Choose how long you want the prism with the offset var, and choose how accurately the pen follows your original drawing. less accuracy = faster! Then press space and watch the prism being created!
