The Extrude feature is the bread and butter of 3D modeling. Imagine pulling a 2D shape into the third dimension—that’s extrude. It transforms 2D sketches into 3D shapes by extending them along a straight path. Select a 2D sketch, set the direction, and specify how far you want it to extend.
For instance, a circle can become a cylinder or a square can become a rectangular prism. Perfect for creating basic shapes like blocks, that their profile extends in a specific direction.
