Object using several materials.

[Anonymous]

Is there a way, for an object using several materials,
to calculate the area of each material?

I can get only the global area (and volume) of the object.

Bonjour Olivier

Which kind of object is concern by your demand ?
How do you determinate —and affect— your different materials to your object ?
Can you create parameters —inside your object— which can to help you to calculate the area of the several materials?

By example it looks easy to calculate —by using the inside parameters of your object— the area of the different materials of an easy geometry object like table, bed or brick. Not really the same problem for more complex one like sanatories, or others non rectangular.

It is for me an inside geometry and programmation object problem but may i am wrong…

For me, the calcul of the area and the volume may be effectuate inside the object and only recuperate by the list or the interactive schedule.

Funny to sppek with you in English…

Hi Fmr,

Nice to meet you here. You don't make a break?
I do most of the calculations by myself, but sometime it is tedious.

Imagine a freeform pool "object", parametric of course. I need the tile area.
If i make the object naked, without water and accessories, i get two visible materials,
one for the exterior, and the other one for the interior (tile).

AC calculates only the global volumic area, ext + int (not so bad), but what i need is the tile area.
Unfortunatelly, i can't find any list global variable allowing to do this for an object.
Or it is in front of my eyes and i don't see it. May be some workaround. Any idea?

Hi Olivier,

I don't make a "total" break, but i'm at home without ArchiCAD to test the solution that i'm going to speek about. But i will test tomorrow…

Is your parametric pool really an "object" ?
If it is, you can in your parametric script calculate —by using your parameter to arrive at this result — the tile area of your spool.
This result is stock in one parameter that you can print inside your object or extract with the interactive schedule.

The tile area will evolue each time you modify your "object" pool.

This solution is not the easier —you need programming the calcul of the tile area inside your object— but I think that it works…

May Someone have a more automatic solution or idea .

Thanks Frédéric. Yes it is an "object", using some SEO and macros for accessories.

That's what i do since years, but what a pain.
In fact i have different color tiles. Some areas are "easy" to calculate, for other one, it is another cup of tea.
Rounded, irregular and parametric forms, not easy to calculate, with the risk of error.

Yes it works, but i am hoping for an automatical calculation. I asked François, he doesn't seem to have a solution.
This slows down a bit my interest for the calc menu, however i have the feeling that AC has the ability to do this. May be i am wrong

Thanks for your input.
