Thank you Gene. I am able to get the correct lengths for individual exterior walls, it seem they somehow resize themselves as I attempt to draw the house box. I'm drawing nothing more simple than a rectangle. I get one of the parrell walls correct, then the perpendiculars change on their own.
Normal, inexperience fumbles, but I thought CA would be a little more intuitive and easy to make a simple house box/rectangle.
I guess we'll see if I can grasp it before I wave the white flag.
Thanks again
