name “HTD1_xxx” and the Filter by WDBLKNAM value option is selected,
the only records that display are listed in the TD table of the catalog database
file that have a blank WDBLKNAM value or a value in the WDBLKNAM field
that matches the block name of the symbol. For example, a catalog lookup
on an on-delay coil (HTD1N.dwg or VTD1N.dwg) displays all blank
WDBLKNAM entries and all entries that include “TD1N” somewhere in the
WDBLKNAM field. If this option is not selected, the query ignores the check
on the WDBLKNAM field and returns all catalog information.
You can do one of the following to determine how your catalog content is
filtered:
1 Add your block name to all WDBLKNAM fields in the catalog table. Using
the example above, you would add the block name to the TD table.
2 Add an invisible WDBLKNAM attribute to your symbol. Using the previous
example, name your symbol “HTD1F” for an off-delay coil or “HTD1N”
for an on-delay coil.
3 Rename your block with the appropriate prefix (for example, “VTD1F”)
followed by a substring “$$” and any other suffix to make the block name
unique. The catalog lookup in AutoCAD Electrical sees the “$$” and
assumes that it, and anything after it, is ignored. It treats your symbol as
if the block name were just the basic name of “VTD1F.”
TIP Option 2 or 3 is preferred.
Overview of the _LISTBOX_DEF catalog database
table
This optional table can be included in the catalog database file. It allows you
to predefine filtering of the catalog entries on the Parts Catalog dialog box.
AutoCAD Electrical normally shows all the entries for the selected catalog
lookup table.
Filtering values can be defined differently for each catalog lookup table. The
first field defines the catalog lookup table name. The next fields follow the
same format and order as the
catalog lookup table structure on page 1274. Leave
the field blank if you do not want to filter the records based on the values in
that field. Access automatically handles the last field, which is the record
number.
