how to draw plans to a medieval / rennaisance manor
I'm trying to draw a plant of a medieval/renaissance manor.
I've read the tutorials but most of them only explains maps kingdoms, cities or even entire worlds. I have some experience in photoshop, but I have more affinity with CorelDraw (which I believe is very similar to Illustrator and Inkscape). I probably need advice on everything: floors, walls, doors, stairs. Also, I just have rough pen and paper draws of what I want.
I know everyone have much to do here, then if you can point me the guides, I'll do it myself.
Thanks in Advance.
