My first model from scratch - our royal living room - help, please?

[AlienBZ]

Just started my first model from scratch - our living room (royal living room actually), and I need some help.

as you can see from the parameters, the dimensions are: L = 49, W = 4, H = 24 (since our living room's actual dimensions are: L = 12, w = 0.5, h = eight) all these measurements are in feet (as I don't know too much metric, only that 36 inches is about 1 meter, 6 feet is about 2 meters) so please bear with me.

one wall in our livingroom is 9 feet long (this is opening into stairwell/front door) and another wall has a big picture window, a third wall has a trapezoid cutout in it (this is opening into hallway/bedroom).

Problem # 1: I don't know how to cut shapes out (for window/trapezoid opening) into walls - how (is this in Max Bible - where?) do I do this?

Problem # 2: When I try to shorten the L of one wall (to provide for stairwell/front door entryway) all the other walls (which were created by cloning as an instance) shorten with it - how to I prevent this so that I can change dimensions on only 1 wall and leave all others alone (intact/unchanging)?

See screenshot:

Thanks in advance.

Answer to problem #1 = Look in your Max Bible for information on Boolean and/or Pro-Boolean operations. Or use Swift Loop to place edges where you want doors and windows. Then delete polygons to create openings.

Answer to problem #2 = When you clone objects, if you want to edit them individually, clone them as a Copy, not an Instance.

make your floor before you make walls. make doorways with pro boolean.
