I have been asked to add a 'contingency' quantity to a schedule, which is a percentage of the quantity in the model. So, for example, if there are 26 in the model, I need to add 4 as contingency, making a total of 30 to be ordered from the supplier.
I'm not aware of Archicad being able to calculate fields - but does anyone have ideas on how to do this without having to export to Excel? Given I have a preview associated with each part, any update would require a re-export of the Excel file, adding of addition rows (formatting, formulas), changing of page layout to export as a PDF to bring back into Archicad.
It would be much simpler if I could keep this in the .pln file as a schedule.
