Which includes me, it’s been my main art tool for twenty years. I’ve seen a lot of people scream about how terrible it is that it doesn’t work like Photoshop.
So really I think that “a serious vector editor” is just gonna be hard for a lot of people to wrap their heads around.
Try sK1[0], Scribus[1] & AzPainter[2] ;)
You'd think one lightly-used (so no deep muscle memory, etc.) vector graphics program would be much the same as another... nope.
It is merely a domain-specific program and requires specific training to use effectively.
This is true of Photoshop, GIMP, Inkscape, Illustrator, AutoCAD, Altium, etc.
Another comment nailed it, they made literally alien UI choices.
It does not feel designed, it feels laid out by a programmer mimicking some other graphical editor from memory on an ad hoc basis.
Having said all that, it still makes sense to me, for the most part. I watched a lot of tutorials when I learned it back in the day, however.
I tried making an SVG manually, using real basic integer coordinates.
Then I wondered if inkscape could do better, and imported it.
It took my nice shapes, like a rectangle from 0,0 to 50,100 and mangled all the coordinates into floating point numbers like 0.0123,0.00456 49.9998,100.00123 (not exactly, but you get the idea)
You have to be careful about when you move, scale, group, ungroup, etc. But I have found it pretty reasonable to stay on nice round numbers with inkscape. I feel like inkspace is BETTER for that than say illustrator.
Worst case you can export as "Optimized SVG" and reduce the number of decimals. Make sure you check it after though since it can change the design when rounding.
Consequently, I find it impossible to do precise CAD style diagrams in Inkscape. Of course, it's not designed for that.
I don't know exactly when/which version, but some time in the last 12-18 months.
Inkscape needs some getting used to for sure but still is a very capable vector graphics editor and I'm glad it exists. Not sure we'd be able to put in the effort into a new tool of this depth if we were to start today (same with GIMP).
I noticed some regression on Ubuntu 18/20 though: the integrated XML editor crashed, and the weird property dialog sometimes doesn't pan into view. Don't know if that has something to do with Ubuntu or gtk/gnome specifically, but Ubuntu Studio appears to have moved to KDE (or alternatively XFCE) recently. And switching to a KDE-based distro such as OpenSuse or Manjaro (or Studio) is what I'm planning to do anyway.
You mean converting scanned drawings image into scale drawings vector form?
