Does anyone know how to enter a "yes/no" parameter into a formula? This is what my formula looks like right now if(A = yes, (B + C), B) A is a yes/no parameter, but this formula won't work.

if(A=1,(B+C),B) When you want to represent a yes no parameter in a formula it is really simple. Yes/On = 1 No/Off = 0.

Hi, Can anyone help me with the following- I want my beams above my doors and windows to automaticly change the beam bearing surface. for example: if my window is less than 199cm the bearing surface should be 25cm -> if my window is 150cm the bearing surface shoul be 25cm -> beam should be 25+150+25 beam = 200cm if my window is less than 299cm but more than 199 the bearing surface should be 30cm -> if my window is 250cm the bearing surface shoul be 30cm -> beam should be 30+250+30 beam = 310cm if my window is less than 399cm but more than 299 the bearing surface should be 30cm -> if my window is 350cm the bearing surface shoul be 30cm -> beam should be 40+350+40 beam = 430cm and so on..

If the beam is not in the window family, then it can't be done. If they are in the window family, then set them relative to the top of the window/door. No need for a formula.
