Subtracting Staircase or atrium

[Shelley4146]

Help...I'm having a senior moment... Subject has a staircase in the middle of the house. How do I draw the second floor with a hole in the middle?? Had this probem before with an atrium on the main floor and can't remember how I did it??m2:

After drawing the area, draw another area for the hole that is set to subtract from that floor level (use the button when you define the area.)

Thank you soo much!!

You're welcome.

ANSI guidlelines say count the staircase, not deduct it. The area below the stairs is counted on the first floor, the area of the stairs is counted on the 2nd. So what's the question again?

 

[Couch Potato]

Mr Rex, that is only when the opening is the same size as the stairs. If the stairs create a hole, it needs to be deducted.

 

[Mr Rex]

But dat not wat she say.

But dat not wat she say.

But why else would she need to subtract?

 

[Mr Rex]

I don't think she does.

I'm with Mr. Rex.
