size_lookup Invalid Input meesage

[Anonymous]

Hi guys,

I'm trying to change the Revit MEP out of the box families and apply some lookup tables in my Pipe Accessories families. I'm stuck with this Invalid Input message when I apply the Revit size_lookup formula. I'm sure I'm using the formula correctly and the lookup CSV file it's ok but I'm not able to get it working.

Any ideas?

Here's the family type formula I'm trying to apply.

Remove the extension .csv from the filename and I expect it will work

Dear EnlInt,

I've just found the solution myself. The five minute brake helped me see the light..It's exactly what you were saying. There's no need for the extensions at the end of the Lookup Table Name.

Thanks for the imediate response.
