Calculation of floor area with room height above specified value

schimmi6 — Thu, 27 Jul 2023 08:22:55 GMT

Hello,

I need to specify for the authority in rooms with sloping roof the floor area, which has more than a certain room height (2.40m) and which less (=remaining area).
Can I somehow integrate this calculation in the room stamp?
Unfortunately, I have not found a calculation approach to this, how could I approach this? Does anyone have an idea?Of course, the values can also be calculated manually, but since we already use Revit... 😉

Thank you!!!

Hi,

If I understand you correctly you want to set a computation height te calculate? Like the printscreen below?

Hi,

I need the floor area > H and the floor area <H. See picture below.

I don't need the volume calculation in this case, but the base area in the solution in your picture would be exactly what I need. However, if I change the computation height, the room volume and area is no longer calculated correctly...

This computation height applies to area as well.

Yes, but the room area in the room stamp then also only shows the area above the computation height, the area below is "lost".
I still need the total area of the room, but additionally the division >H and <H

Hmm, as a workaround you can add a Room Separation and then add an extra room:

Using this method, you'll have the advantage of having both areas, which enables you to create a schedule and use formulas if needed.

How are you presenting this? If it's a schematic view you could create area plans, one with whole area, and for another use reference planes to determine the boundaries of "height less than" areas.

@ralphdenhaan

The idea with the two separate rooms is not bad, however, there is still the problem that the total room area in the room stamp is not correct...

@blank...

I basically just need to present this in text form with the room stamp, like in the picture below.

In the floor plan, I need to draw a dashed line that marks the height. Currently I do this with the reference planes as you write, I calculate the areas with temporary "filled areas". Not smart, so I was wondering if I can automate this (at least the calculation). The line in the floor plan is probably faster to do manually than to generate any other plan views.

Just thinking if it were me I would duplicate the floor plan and set a new work plane (level) for the room sizes at the level you want and mark that plan as level x (insert your reference there) (like a room perimeters at x height) floor area (annotated a little section next to it for clarity of the level if you want) then have the floor level plan next to that or on the previous / next sheet with that room size - this is because each new sheet you can add another set of room tags as a fresh layout

then you will be building up sheets of various information in your schedule list and you can annotate, description, comment etc.

since using Revit, in place of layers (CAD world), where things could be turned on and off in PDF, - in Revit I use multiple floors with different levels and sections to show various points such as this? otherwise you end up with too much information
