I've been hoping for inkscape to get usable for ages. I will always give it another shot.

So after trying it out, I will say it has improved a lot compared to 5-10, even 2 years ago. Some strange and unconfigurable UI decisions that waste huge amounts of screen space--- it takes about 3x as much as it should for what is displayed. Only my small laptop display the interface takes >25% of available screen real estate. It would be impossible to do anything substantial. They're still working out how to implement pallets-- but at least there are pallets now.

For this basic application I can deal with little odd stuff; every program has them.

Small problems for the question I posed: No unit of feet, but does have inches. There is a way to type the dimensions tho it's not as smooth as Sketchup and it sometimes adjusts the values

I entered 58" but it became 57.570".

Main problem: Terrible stability. It has required hard reboot of my computer twice and killing the application numerous times. They have some documentation about how to avoid these problems but none of them apply here. The first time it crashed all I had done was draw 2 plain rectangles. I have a pretty stable system, this is very unusual.

Also here is something fun: Preferences don't appear to be saved unless you properly exit. So when I spent time setting things up, then it crashed, everything went away. I experimented by setting a pref then quitting vs setting a pref then killing. Killing results in reset of the pref.

Crashing and stability aside it is massive improvement.
