Truth be told, I can’t stand Inkscape. It always seems to be getting in the way. I can use Linux for most things, but Inkscape is just no Illustrator.

But this is the one thing (I can’t think of any others) that Inkscape gets right I figure the top-left origin is used my many programs because that’s what all you geeks’ IBM PCs did back when.

Sketchup, for example, uses a normal coordinate system, and I don’t think that’s a “tech geek” app.

As far as I know that is leftover from Sodipodi. Mathematicians and tech geeks seem to like it. There may be some trickery you can perform using Viewboxes to get around this, I’m not certain though.

Inkscape needs more feedback from artists like you to help balance out all the request for technical drawing features.

Fixing or choosing the x-axis determines the y-axis up to direction. Namely, the y-axis is necessarily the perpendicular to the x-axis through the point marked 0 on the x-axis. But there is a choice of which of the two half lines on the perpendicular to designate as positive and which as negative.
…
The standard way of orienting the axes, with the positive x-axis pointing right and the positive y-axis pointing up (and the x-axis being the “first” and the y-axis the “second” axis) is considered the positive or standard orientation.”

You seem most upset that it’s on the *left*. I don’t know anybody who puts a 2 dimensional coordinate axis starting on the right.

The main problem, in my opinion, is the direction of the “Y” direction, that is reversed in the “computer” way in relation to the cartesian plane.
