OK - Im a total formual Newbe

What I am trying to do is generate a volume formula within my family.

I have set the following attributes

Shelf Volume

Shelf Width

Shelf Depth

Shelf Spacing

Shelf Thickness

Bracket Height

 

therfore my formula is LxDxH(which I cant get working)

Shelf Volume = (Shelf Width * Shelf Depth) * (Shelf Spacing - Shelf Thickness - Bracket Height) * 4

As there are 4 shelves I add the * 4 at the end.

Can some1 tell me what I am doing wrong???

I wish there was dumb down instructions for formulas :|

Are you getting an error or is the number that you are getting DEFINITELY not the correct answer?

 

Also, I'm guessing the Shelf Volume parameter is the total volume of all the shelves of the family combined?  Are the shelves uniform or is each shelf a different width/depth/thickness?  If they are uniform wouldn't it be easier to do (Shelf Width * Shelf Depth * Shelf Thickness) * No of Shelves ?

I see now, you're looking for the total volume of empty space between the shelves.  That makes more sense than calculating the total volume of the shelves themselves. :D  If you have a parameter for your side, top and bottom pieces the could befairly painless:

 

((Height-(Header Height-Footer Height))*(Width-(2*Side Thickness))*(Depth-Back Thickness))-(No of Shelves*(Vol of Shelves)

 

 Make sense?
