Please note: 2 plane axis creation (at 3:40) is not working anymore, please use the cylinder axis creation.
In this video you can learn how to design a screw (threaded bolt) in Shapr3D.
Start with a basic sketch, revolve the closed sketches and use the revolve tool with the height function to create a spiral (helix). Using a construction plane and construction axis can help you to model faster and be more precise. Finish your work with an extrusion offset and chamfering the sharp edges.
