The video series will focus on creating a D20 die, a 20-sided object made of triangles forming a sphere-like shape. The golden ratio (1 to 1.618) and Fibonacci sequence are crucial for this project, despite the project being one of the most challenging in the course, involving 3D drawing with X, Y, and Z dimensions.
To create anything in CAD, you need either available planar faces at the origin point (like the YZ, XY, or XZ planes) or an existing flat face to draw on. The example D20 only has text on one face for demonstration purposes; however, the principles taught can be applied to all 20 faces for a fully functional, printable D20.
To begin, create a new design. You need an origin plane or a planar face to start a sketch. The project will use millimeters for measurements to simplify calculations involving the golden ratio (10 to 16.18). The first step is to create a new sketch on the XZ plane (top view).
Use the 'Center Rectangle' tool, which you might need to pin to your toolbar for easy access as it doesn't have a hotkey. Ensure 3D sketch mode is enabled. Draw the first rectangle from the origin point with dimensions of 10 mm wide by 16.18 mm tall.
Using the view cube, switch to the left view and draw a second center rectangle directly on the face of the first rectangle, making it 10 mm tall by 16.18 mm long. Then, switch to the top view and draw a third center rectangle on that face, measuring 16.18 mm by 10 mm. It is crucial that these rectangles *do not* have touching edges; they should only share the concentric midpoint. If edges are touching, the dimensions are incorrect.
