I’m trying to create a Revit MEP family using the lookup table method and I’m suffering a problem that I don’t know how to be solved.
Asking for your active help.
The problem can be summarized as follows:
When trying to create the Revit family the following massage appears:
Invalid formula found in the "B" parameter in the " " type. You will need to import the correct table or edit the formula in order to continue.
Although I think that the formula entered is correct and the file imported is of .CSV format
Attached the error and a print screen of the entered formula.
Please Advise.
