I do the same thing in Inkscape for layouts.I use visio, you can find unused older versions for fairly low price on eBay. I uploaded inkscape just to see and realized it's a Coreldraw clone which as you say is not very intuitive.
Visio is far better, you can control placement of objects to 1/1000th of an inch.
Some of the things I've drawn
