Last week a user asked me how to push the custom USER data to symbols. He created USER1 and USER2 attributes and then edited the catalog data expecting it to update. However this information is not pushed from the database. CAT and MFG are the only columns that push to symbols. The rest of the columns are pushed to reports but not to symbols.
So the question is… Is this possible? Yep. And you already have access to it. It’s in the AutoCAD Electrical help system. It’s in the form of a sample AutoLISP utility in the "API" section of the help under Section F: ace_get_cat_data Function. The text is at the bottom of this post if you can’t find it… I can’t seem to locate the API Help in release 2013.
This LISP is currently pulling USER1, USER2, and USER3 columns from the catalog and pushing them out to selected symbols with the same named attributes.
You could easily edit this script and modify it to push any other columns by simply modifying the existing code or adding a few new lines. The function c:ace_get_cat_data pushes out the data in list form. The help shows what order the columns are reported in. And the LISP refers to the columns by number in the order each column is listed in. USER1 is 12.
(if (/= (nth 12 cat_rec) "")
captures the 12th number in the function report and
(c:wd_modattrval ben "USER1" (nth 12 cat_rec) nil)Pushes that same 12th value into the USER1 attribute of the selected block.
I posted a copy of this LISP here:
Automatic Display of Internal Part Numbers on Electrical Components.lsp
APPLOAD it and then type user_cat_2_symbol and press enter to run the LISP.
