		<description>Tech geeks?  That&#039;s not me...

Truth be told, I can&#039;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&#039;t think of any others) that Inkscape gets right  I figure the top-left origin is used my many programs because that&#039;s what all you geeks&#039; IBM PCs did back when.

Sketchup, for example, uses a normal coordinate system, and I don&#039;t think that&#039;s a &quot;tech geek&quot; app.</description>

		<description>&gt; why the heck is the “origo” (0,0) in the bottom left corner of the canvas??

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&#039;m not certain though.  

Inkscape needs more feedback from artists like you to help balance out all the request for technical drawing features.</description>

		<description>It is due to sodipody legacy. The developers are working on flipping the coords, but it is a complex task which could destabilize the code base and noone is currently working on it full time.</description>

		<description>Weird, especially considering that the &lt;a href=&quot;http://www.w3.org/TR/SVG11/coords.html&quot; rel=&quot;nofollow&quot;&gt;SVG specs&lt;/a&gt; put the origin at the TOP left of the page. For some reason I never noticed that before -- I usually use the grid rather than look at the numbers...</description>

		<description>&quot;In two dimensions:

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 &quot;first&quot; and the y-axis the &quot;second&quot; axis) is considered the positive or standard orientation.&quot;



You seem most upset that it&#039;s on the *left*.  I don&#039;t know anybody who puts a 2 dimensional coordinate axis starting on the right.</description>

		<description>As a mac developer I know that all of OS X views (NSView subclasses) have the origin in the bottom left corner. Apparently this is how PDF works too.</description>
