Comment 3 for bug 657284

> dimensions and grid correspond to how the file is displayed/scaled by default in QCad
- cool, that is gratifying to see, I don't ever modify the default scale in Inkscape, so I had never attempted that

- with respect to the scaling of the <svg> element at 100%, that was done as an act of desperation because I could not come up with a better answer. The AutoCAD procedure for specifying the size of the document is so convoluted that I have never been able to figure it out, and in Inkscape ideally I would have preferred to read the existing size of the Inkscape document while importing the data, but I don't know how to do that from inside Python. There are Inkscape verbs for querying the size of objects but they are of no help as far as I can tell because they return only bounding boxes, not document size. So I was not able to come up with a meaningful definition of document size and used 100% only for lack of something better.
