Combine calculations from area area and room area

[hve-architecten]

Hello,

I have a question: i have 2 schedules, one with Area areas and one with Room areas. Is it possible to calculate the percentage of these two areas?

No. But you can create a new Parameter and add it as a field to the Room schedule, manually enter the Area value, then create a calculated value to get the percentage for each room.

Thanks!

Created a new project parameter (Area_verblijfsgebied) but now i cant calculate the percentage of 1 column to the other:

I just want for instance calculated that 88,9 / 160,7 * 100 = 55,3% !  I just cant get the formula right!

.....and Revit give you the 'inconsistent units' message, right?

Here's what you do - divide all the areas by 1.

Area/1.

That's it. This will make the units consistent.

Strange things happen in Revit:

Tried the following formula: (Area_verblijfsgebied / 1) / (Area / 1) and the result is this:

1,1 is just incorrect, needs to be 0,553. And some fields are empty?

Do you have combined rows?  Check [Itemize every instance] under Grouping.
