: Inkscape: Drawing a perfect circle in 2 point perspective Is there a way to draw a perfect circle in a 2-point perspective drawing in Inkscape? I'm looking for a way that I don't need to

Unfortunately having only a projected rectangle does not define how a circle should be projected. A projected rectangle can present infinitely different rectangles seen in different projections. To remove the ambiguity you must have a square seen in the wanted projection.

Let's assume you have a properly projected square. It can be made using a descriptive geometry construction, calculated, copied from already existing image or simply drawn using artistic intuition "This is how a square is seen from my wiewpoint, no matter if it's a little tilted"

Fitting a circle to the square:




draw a circle, select it
insert path effect Perspective Envelope
select the envelope
use the node tool, drag the corners to the corners of the projected square


Be sure you have enough snaps to points ON (crossings, nodes)

To draw this accurately use Sketchup ("Make" is free)

and export as pdf. svg here: SVG



if you want it like this

just do this make sure both are paths

you copy your perspective rectangle
you rotate the copy to sit horizontally on the ground
you skew that copy, so that the bounding box is a rectangle
you draw a circle which fits at the bottom
convert to path, move the control points left, top and right to their place at the border and adjust the control tangentiales to the shape
you group shape and circle
skew the rectangle to the figure 2
rotate it to fit to figure 1, ungroup


It is easy to find the correct angle for rotation and skewing in step 7 and 8, if you align both objects by their center, first.

Maybe you get similar results, if you apply the procedure 4, 5 directly to figure 1.
