VOLUME3D() in Property Script

jonasm

I built a GDL Object to represent a precast concrete object that has a few modifiers, to be adusted to different situations in the building. Now I would like to put the Volume and Total Surface into Parameters to read them through Labels and write them into a IFC File.

 

I discovered Volume3D() and Surface3d(), those produce the desired value. Only problem, they are only executed in The Property Script. I have read somewhere that I could use the TEXT I/O Addon to write the values into a text file, and then read them again in the 2D script. But I can`t get the TEXT I/O Addon to work.

 

Here is what I am trying, but it is not outputting anything:

 

!! 2D Script

ch1 = OPEN ("TEXT", "volumen.txt", "MODE = RO, LIBRARY")
_volumen = input(ch1, 1, 1, var1)
text2 0, 0, _volumen
CLOSE ch1

!! Property Script

ch1 = OPEN ("TEXT", "volumen.txt", "MODE = WO, LIBRARY")
OUTPUT ch1, 1, 1, volume3D()
CLOSE ch1

Hi.

We can also try the Volume (built-in parameters) fr. archicad's properties (property manager)-- can be use in labels, as well as generated in IFC formats. e.g. create a property , then map the "Volume"  to your customed properties (volume as type) and link to all classification...this is faster & easier.

Hi,

I had tried Volume (gross) first and that does not calculate for gdl object. Wiredly though it does work with Volume (net).

Thanks for pointing me into the right direction.

Anyhow, the OPEN command doesn't create the file, it has to exist.
