how to add length and width of a room as parameters in schedule properties

[linaa2016]

when i create rooms i can get the area and add it to the quantities because i find it in schedule properties but how can i add length and width of a room in the quantities i tried a lot but couldn't figure it out so any help would be appreciated thank you

side note: only works for rectangular rooms.

aren't all rooms rectangular?  LOL

Out of curiosity, what are you going to do with length and width of room?  There might be another way to get there.  

[linaa2016]

thank you i checked it and i understand now how to get the calculations of the length and width but i want to add them to the quantities and the room schedule and i don't think it's mentioned there.

[linaa2016]

i want to add them to room schedule.

I understand that. My question is why do you want to add them to a room schedule?  

[linaa2016]

the client wants them to be in schedule i mean length and width of each room instead of being written on the plan so i thought about the way to do that in revit. 

[barthbradley]

So what does the client want you to do in this case? 

[linaa2016]

ok i understand you and a similar case is explained in the link posted above but there isn't something like that in the plan anyway.

There is no way to automatically do what you are wanting, unless all the rooms are perfectly square.  If they are all perfectly square, then you can create a Calculated Parameter Column for "Length" with the formula =Perimeter/4, and a Calculated Parameter Column for "Width" with the formula =Perimeter/4.

Although true, better use the other method for that one aswell. I doubt your rooms are perfectly square^^

1) Add Area & Perimeter to schedule

2) Insert calculated value for width (based on quadratic equation)

3) Insert calculated value for length

Only works for rectangular rooms, else you might have to use Bretschneider's equation as RDAU points out/explains at the bottom of this topic. You could also add a project parameter to check/uncheck if the room is rectangular, and then base the calculation/value on that.

thanks to all the comments and with some search i could get it to work thanks all again.

You can do it for a rectangle also, as there is a relationship between perimeter and area to determine L and W.

Yes, I'm aware of that. Our Room Tags can display nominal length and nominal width (via Calculated Parameter Labels) if the Room is rectangular. That solution was given in the Message #1.  

correction: @hmunsell posted a link to the solution in Message #2.
