The goal of this instructable is to CAD a D4 with only 1 parameter
Supplies
CAD Software, I use OnShape as it is free
Base Triangle
![Base.PNG](/proxy/?url=https://content.instructables.com/FVH/NV72/L4E6GL8J/FVHNV72L4E6GL8J.png&filename=Base.PNG)
- Make an equilateral triangle whose center is on the origin
- Add your one dimension to say how big the triangle is
- Add a construction line from the constrained point down along the "Right" plane
- Make the construction line be equal (same length as) the side of the triangle
Find the Top

- Make a construction circle whose radius is the length of the side of triangle
- Draw a construction line up from the origin to the circle
Loft the Triangle

You now have a "blank" D4!
Feel free to add numbers to it or whatever else you want!
