Supplies
CAD Software, I use OnShape as it is free
Make a Square
![CenterSquare.PNG](/proxy/?url=https://content.instructables.com/FMJ/EN2X/L4E6GKAU/FMJEN2XL4E6GKAU.png&filename=CenterSquare.PNG)
- Make a Square whose center is on the origin and the points are on the axis of the other planes
- Add your one dimension to say how big the square 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 square
Find the Top and the Bottom

- Make a construction circle whose radius is the height of the square
- Make two construction lines from one point to the edge of the circle
- The lines should end on the front plane, above and below the origin
Loft

Finish!

You now have a "blank" D8!
Feel free to add numbers to it or whatever else you want!
