I'm looking for a solution both for a current plan I've already drawn and for an easier way to do it in the future, so it sounds like I should try a polyline mask for the current plan and place interior walls on their own layer in my template for future plans. Now my question is, how do I do either method? For the polyline mask, do I use the "make living area polyline" tool then change the fill to solid white? Or is there a better way? I have tried creating new layers using Default Settings->walls-> Interior walls -> layer -> define -> copy (then edit the name to be walls, normal interior). It doesn't seem to make any difference. Is that because the walls are already drawn? If I did this before drawing any walls, would the interior walls be on a different layer I could turn on/off independent of the exterior walls? Or am I doing it completely wrong?

How do I display the exterior walls but not interior walls in various layer sets? I know how to turn the Walls, Normal display on and off, but I only want the exterior walls showing in both my roof plan view and plot plan view. Is there a way to separate exterior and interior walls so I can turn the display on/off independently of each other?

I usually print layouts on 24"x 36" paper so that is what my layout template is set up to do. A client wants to print on 11"x 17". When I change the size of the drawing sheet, it changes the paper size without adjusting the title boxes, notes, etc. Is there a way to resize the entire layout without creating a new layout template for 11" x 17" paper?

Is there a way to change how square footage is calculated? Our appraisers calculate square footage based on exterior dimensions, so the living area square footage that shows below each plan is significantly less than the total square footage. I know I can change rooms such as garage, open below, etc. to be included rather than excluded from the living area calculation. However, even including all rooms, the living area will still be less because of wall space. I am using Chief Architect Premier X11 on a PC computer.

I'm trying to change the material for the trim alongside my stairs independent of the riser material. I want the trim to match the baseboards in the rest of the house and the riser to match the tread. Is it possible to separate the trim and the riser material in the stair definition dialog?
