This tutorial is specially designed for beginners. You'll discover the essential features of the software and create your first project in no time. 1. Pad The Pad command is the primary tool for linear extrusion. Action: It pulls a flat 2D sketch straight out into the third dimension to create a solid body. Typical Use: Creating blocky, flat, or prismatic base shapes (e.g., turning a square into a cube). 2. Revolve (Revolution) The Revolve command is the primary tool for circular extrusion. Action: It takes a 2D sketch and spins it around a center axis. Typical Use: Creating cylindrical or spherical parts like shafts, wheels, knobs, or pipes. 3. Chamfer The Chamfer command is a finishing tool used to bevel sharp edges. Action: It cuts a flat, straight angle (usually 45°) across an existing edge. Typical Use: Removing sharp burrs, preparing edges for welding, or creating a "lead-in" to make inserting pins or bolts easier. 4. Fillet The Fillet command is a finishing tool used to round sharp edges. Action: It replaces a sharp corner with a smooth circular arc. Typical Use: Reducing mechanical stress concentrations, improving aesthetics, or making parts safe to handle. 5. Mirror (Mirrored) The Mirrored command is a transformation tool that creates symmetry. Action: It duplicates a selected feature (like a Pad or a Revolve) or the entire solid body across a reflection plane. Typical Use: Modeling only half of a symmetrical object to save time, then reflecting it to create the complete, perfectly mirrored part.
