In this CAD tutorial we'll use the features: 


  • Extrude: This is the most fundamental command used to turn a 2D sketch into a 3D solid. It works by extending a sketch profile in a straight line, either to add material (a "join" operation) or to remove material (a "cut" operation).

  • Fillet: This command creates a smooth, rounded edge on a part by adding or removing material. You can choose a constant radius for a uniform curve or a variable radius for a curve that changes along the edge.

  • Hole: This is a specialized tool for creating different types of holes in a part. Unlike an Extrude Cut, which just pushes a profile straight through, the Hole command offers options for various hole types, including simple, tapped (threaded), clearance, or countersunk holes. It saves time and ensures accuracy by automatically handling the geometry and thread specifications without having to manually sketch all the details.


All dimensions are in mm/g/s/ISO
