Inkscape: create inner gear


Question

Using Inkscape, I want to draw a inner gear.

In Inkscape, there is useful extension to draw a gear. I've used that extension to draw gear with tooths pointing to outside of a circle, like so:

enter image description here

but I want to draw a gear with tooths pointing to the center of a circle -- draw a inner gear:

enter image description here

Is there some tool, which will allow me to flip a tooths of outer gear around the circle, so the tooths will point into a middle of a circle? Or, how You would draw such shape?

  • You can just interprete the space between the teeth of an outer gear as teeth of the inner gear and vice versa. This may not be very realistic but may suffice for your needs. For example the following two were generated from the same output of the gear renderer:

    outer and inner gear from the same rendered gear

  • If the above does not satisfy you, the only way I see is something like this:

    1. Create some cocentric circles.
    2. Extensions → modify path → add nodes
    3. Combine everything.
    4. Edit paths by nodes, connect the points as desired and remove the rest. Compare to steps 13–15 of this answer of mine.
