Looking up 2 parameters in Lookup table error

[Anonymous]

So I've tried this a multitude of ways. I keep getting an error on the radius of these Horizontal Tee Lookup tables. Obviously I'm missing something. I tried inputting all of the possible radius combinations, but that didn't help either. Any ideas... I've attached the csv and the family.. It works fine with all VIB, VOB, but I can't seem to get the HTee working.

Thanks for any help..

Check one of the families in the Autodesk library (here "Tee - Generic.rfa" from the UK library)  how it is organized.

You can see that a lookup table is imported into the family

Also it contains a parameter to the lookup table (i.e. Lookup Table Name).

In your case the manage lookup table is empty

Well, I imported the T.csv into the family. I unload it because of the error the size_lookup gives me. I'm not sure what the problem is. I see your syntax and understand it. I must be overlooking something.

Thanks for looking at it.

Any ideas from the experts? Thanks in advance.

Like L. Maas said.

You need to import the LookUp table in your family and work with a parameter for the lookup. See snippets below:

And this:

Extract info from lookuptable like this:

Another thing I got problems with in the beginning, is the right format of the .csv file.

Try use the added file, and adjust it for your values.

Another thing I see.

You have text values (G and V) in your lookuptable.

Lookuptable can only be used for length parameters, NOT for text. Only position text can be used is the first column.

Not certainly in that way. Starting with the 2018 version size_lookup can be used for TEXT parameters from any column.

Yes I've been using lookup "BOM" which is BOM##Other## from other columns with no problem.

I had two problems which I have resolved. One is the Horizontal Tee has 4 radius on the pull down. I had to list the Lookup Table on each one. Also on my T Main Width and my T Sec Width I had it as 0'-6" instead of changing it to decimal inches. Now it works great. Thanks so much for the help.
