I'm trying to make a drawing of the interior of a Stanford Torus, similar to this:

enter image description here

Is there a way to draw the perspective of the torus accurately without using a 3D model?

  • Any software in particular?

1 Answer 1


I would start by drawing the axes of the walls and the ceiling.

1 Drawing the left wall bottom line (red) and top ceiling (yellow). Drawing the right wall bottom line (blue) and top ceiling (lightblue).

2 Cmd+B to apply Blend (Object>Blend) from red to yellow first and from blue to lightblue after.

3 Define the amount of steps Object > Blend > Blend Options > Specified steps

4 Mask the blended objects on the illustration frame.

Tip: for blending is always better to have the same amount of points on each vector, on my sample just two, star and end points.


Same with arcs:
