Wall area into multi category schedule. How to?

[ConstantineC]

Hi, I would like to calculate the gross wall area of a facade that includes the openings.

In the multi category schedule I can`t find the Area parameter. In fact there are no built-in dimension parameters. How is this possible?

I am able to manually duplicate the value of the Area built in parameter of the wall and  add it to a  Wall Area as a Shared Project Parameter field and then use it in the multi category schedule. Is it not possible to retrieve this Area automatically?

I managed to get this schedule format by grouping and filtering windows areas by wall mark but the calculated parameter doesnt work

This is happening because the fields are not actually combined. Window and wall areas are separated.

Is there a way to add Wall Area to New Window Area total by Mark grouping?

[ConstantineC]

Finally, I think I was able to get glazing percentage by wall mark using Material Multi Category schedule

I used a Calculated Value percetage parameter and I was able to calculate each material area to grand total.

I know that for a more accurate value I should add another parameter for each window to add the frame width.

I wish I was able to use the subtotal instead of Grand Total so I can have a single schedule for all wall marks but this is fine too.

EDIT

There is a problem, the glass material area is more than the calculated value of Width*Height of the window (New Window Area) so something is wrong.  2.75 vs 1.67 sqm...

What could it be?

Let us take a look at your RVT. Post it here.

The easiest way is keep walls in phase 1 and opening in phase 2.  Set the wall material take-off schedule to phase 1 to calculate gross wall area without opening, to phase 2 to calculate wall area with opening.

@barthbradley Here it is. Just a mockup to test the schedule. Thanks.

There might be something with the window family too, I just randomly choose a type.

Thanks that sounds like a reasonable automatic way but how many phases will you end up with ? Will you have Phase 1 and Phase 2 for the schedule and a main Phase 3 to have eveything? Or will you just 2 phases?
I want to understand which will be the main working phase.

You only need two phases. One phase calculate the opening of the wall and the other phase is for total wall area. See attached how to set them up.

Are you after something along these lines?  See attached RVT.

You know, Roombook Extension might be the ticket here for you.  Download/install it via your autodesk.manage.com account portal.

Yeah that is a way to do it but only for horizontal walls. If you have walls/facades that connect to a sloping roof its not working.

[ConstantineC]

Thanks!  I think this is  the most convenient way!  I can also filter or group them to separate the grand totals per each facade.

That's why I suggested Roombook Extension.  No gymnastics/workarounds needed if you use RB. Pretty painless too. 😉
