Schedule for walls isnt showing correct

Hello folks

 

I have a small case of revit not calculating the way I want it to calculate. Or we think of the same calculations in different views it seems like.

I have a couple of rooms wich I calculated with length, where revit also came out with the same answer. Then I added length to make the square meters. Allready there me and revit are arguing what is correct and not.

What or exactly how revit thinks about it seems odd for me. Since it simply needs to do the length times height and you will get the correct answer.

 

Is there a way to enter the calculations to view or make a new rule for calculating?

What are you trying to achieve? Calculate areas of walls in each room?

Maybe try the Roombook addin.

What I am trying to achieve is to calculate the area for the "type walls"
For each room I can use section room. But in this case I want the total of the selected rooms.
I.E
100mm room X m2 150 meters
120mm room X m2 243 meters.
etc.
As mentioned the length is close enough, but the area (face of the wall) doesnt calcuate correct.
I can also mention I use the light version of revit.. So I cant use the addons sadly enough..
But then again this issue should be a reasonable fix for, but I cant see how

So if you are using LT (which doesn't do MEP) and this is an architectural question it might be better to move it over to the architectural forum?

@iainsavage LT doesn't have MEP support? I honestly had no idea. I have never had a need to use it before, but assumed it had "lite" support for all the disciplines.

 

For the Area issue.... I think what might be happening is the Length of the wall that you see in the properties window is not necessarily the length of the Finished Face.  It is from the End to End length, which may be imbedded into the opposing wall.  So there could be a difference between the area (Height x Width) of the "Wall" and the "Finish Face" surface of the wall depending on how its calculated.

Have you tried using a Material Take Off schedule? They may give a more accurate "surface area" measurement.

Material Take off Schedule is new to me.
I see what you are meaning, but as I stated. The total length of the walls are correct. The wrongs that are shown is the square meters.

How are you getting the data for walls in each room? Are you doing this manually or using a schedule or a Dynamo script or how?

When I create a room schedule the only schedulable walls category is wall finish - so you could maybe apply a finish to the walls and see if that gives the correct answer.

I make the Revit count the length and area of the "type wall"

As shown here.

I thought you were wanting the wall areas in each room? How do you know which room the walls are in?

Also when you say that your calculation and Revit's calculations disagree, to what extent do they disagree? Is it a significant percentage? Could it be, as @hmunsell suggested, to do with the joints at corners, intersections and at joins with floors etc?

Someone on the Architecture forum probably has a better understanding of how this works in Revit.
