i'm trying to find a way to calculate material cost
I did the following : Check the attachement 1
it doesn't work...
second thing, can i use the function "if" to do the folowing inside the same formula ?:
if untit = m² ==> price per unit x area
if untit = m³ ==> price per unit x volume
or i create a propretie with multiple formulas each one with seperated condition
i believe there is a way, i have tried several times without achieving a good result
Unfortunately, what you are trying to do is not possible in ARCHICAD at the moment, because Building Material Properties cannot be Expression-defined. Probably this is the reason why the Dialog says "Not applicable". This is a current limitation and I don't know if there are plans to develop it or not.
You can make a wish for this feature, we can vote on it and if it gets enough support, we can submit it to GRAPHISOFT for consideration.
If you do make a wish, please post its link in this thread.
