Surface area calculation in revit.

[Anonymous]

Hello all

                 I am trying to calculate the surface area of beam (for example) from Revit. After getting the surface area I have to show it in beam tags too. How can I do that ? Please find the attached PDF. Please try to help Asap.

edit the beam family, replace width and height with shared parameters; create a new beam tag and add calculated formula based on shared parameters and beam cut length. (you'll need at least Revit 2017)

you should first change the beam hieght and width to shared parameters, and create a schedule after that create a calculated value parameter based on width and hieght parameter, 

so you need to create a calculated value for cross sectional area which will be height x width

then create side surface area which will be length x height

and bottom area which will be length x width

Finally create a calculated value for total area which will be bottom , surfaces and cross section area

If you only need to report the Surface Area in the tag then the only shared parameter you need is Surface Area, not the dimensions of the beam, and it can be done in any version, not just 2017.

- Create "Surface Area" shared parameter, add it to the Beam family, add the formula (in the example I calculate the total for all sides but it is up to you)

- Add the same shared parameter in a label of the Tag family, no formula needed

- Load both in project and done

he wants only 3 sides ...

I said in the post that I did for all sides as an example. The method doesn't change.

Perfect i liked it , simple and serve the purpose

What if my concrete beam is composite with the slab that is 12" thick, essentially reducing the area of the beam sides by the thickness of the slab (36" deep beam, would only drop 24" from u/s of 12" thick slab). How would you calculate the correct area of the beam without the slab? I don't need the tag, just want to schedule the area. Thanks.
