From other CAD software, I'm accustomed to being able to position an object in a drawing by it's center. For example, I want to locate a 1/2" circle at grid coordinates X 1.000, Y 1.000. In Inkscape, I can create my circle, no problem, and I can enter the X and Y coordinates of 1.000 and 1.000 and the circle appears - but the lower left-hand corner of the box that surrounds the circle is at that location, not the center of my circle, which is in fact at X 1.250 Y 1.250.
My question is, how can I change the reference point, "handle", or whatever it's called in Inkscape to the center rather than the outside corner of this box? I can't believe this is not the default, but I also have not been able to figure out what Inkscape calls this, and how to change it.
I would find this very useful, too. Maybe one of the challenges, though, is to define what “center” means. For regular polygons, and for rectangles, it’s reasonably straightforwards. For other shapes maybe we’re looking at a centroid or something that might not even be ‘inside’ the shape.
So I am wondering — what if “center” defaults to something simple-to-calculate and usually simple-to-understand like a centroid or the center of a rectangular bounding box, and be moveable?
