If you can get your head around 3D cad, plans become very easy. I use TurboCAD Deluxe - Advanced & Affordable 2D/3D CAD Software. There is nothing like drawing up in 3D, and then being able to rotate and explode whatever it is you are drawing to get all the cutting dimensions.
You have to get your head around the fact that everything you draw starts on the workplane, but get that and 3D drawing starts dropping in to place. Makes things very easy - for example, you can draw one 3D part, and then subtract it from another part to create the joint, then just measure the dimensions.
