Inkscape: A Vector Drawing Tool

Can I force drawing circles (not ellipses)?

Asked by Melaneus on 2012-09-09

For the intent of making geometric constructions and for other uses, I want to be able to draw circles and not have it attempt to make integer-ratio ellipses when constraining their shape (with the ctrl key). Is there a way to force the circle tool to be constrained to 1:1 circles?

(The option when drawing a circle says "with Ctrl to make square or integer-ratio ellipses", I don't want the integer-ratio part)

«To force a circle to be drawn, hold down the Ctrl while dragging the mouse. (…) Holding the Shift key down while dragging will create an ellipse centered around the starting point.»

Holding Ctrl+Shift keys while dragging will allow to draw a circle around the starting point.

For more details, please read the related section in the manual:

I updated the question to be more specific to what I'm looking for.

No, there is no such option to constrain to ratio 1:1 only - drag diagonally with 'Ctrl' pressed to create a circle.

Maybe you want to consider using either a real CAD application (e.g. LibreCAD, or FreeCAD), or an interactive geometry, algebra, and calculus application like e.g. GeoGebra, Euclide, C.a.R. or KiG, which are better suited than Inkscape for such tasks (Inkscape's support for technical & geometric drawing is still rather limited, though steadily improving).

Thanks to Inkscape being open source, I was able to reprogram the circle drawing method to act the way I wanted.
