This page describes how to create Calculated Attributes in dRofus. Using the Calculated Attributes feature, you can build formulas dynamically using available dRofus fields to create additional fields. Calculated Attributes are available for Rooms, Items, Occurrences, and Products and allow you to build simple to very complex results. We explain how to do this for Room Calculated Attributes, and on this page, we will go over how this can be done for items. The Calculated Attribute Formats are the same across dRofus. A good baseline understanding of how Item Composite Text Attributes work is a great place to start since the rules can be combined with these attributes. The Room Subtraction Example was a simple one that could be applied to items, but we will go more complex for this example.

You need admin access to the database to create calculated attributes, as the setup is done in the Administration settings. Please refer to Project Administrator. |

This feature can not be exported to xml or PDF, but is available in Excel Exports and Revit/ArchiCAD Add-On configurations. |
Item If/Then Example
You might be familiar with if/then formulas if you have ever built complex rules in Excel. The syntax of IF-THEN is = IF (logic text, value if true, value if false). The first argument tells the function what to do if the comparison is valid. The second argument tells the function what to do if the comparison is false. A quick search on the internet will result in several examples of this concept. In our example, we will use several rules to pull from item data to inform some results. If you have ever tried to determine Door Calculations, you will want to bookmark this page and impress your office. Our team in Australia came up with this idea, and we all think it’s a great example of using item data to inform other decisions.
