Expression Editor / Parameters and Properties

Njegos T
Hello everyone,

I'm trying to create a surface quantity scheme with multiplied material prices. In the scheme settings under the Fields we have options Projected Component Area (Net). It is a parameter that multiplies by the price. When I go to Property Manager to create an expression I can't find the same parameter as I set in scheme settings.

Is there any other way to solve the problem?
Properties cannot detect composite components parameters,
you can do calculations on excel side, export your schedule as excel, link it to an scel sheet that countains formulas to multiply price by quantity

Component_NetProjectedArea is available in Python Parameters. You could do your calculations in a single click and then write back to a element property which you created. That property would then be able to be scheduled. This would avoid having to mess with excel and only involve a single click (execute script) to update?
