A dimmed WEBLINK edit box in the Edit Record dialog box means that the
catalog lookup table does not have a WEBLINK field defined as the fifteenth
field. If dimmed, you can add this field by manually adding it to your own
copy of Microsoft Access.
A Weblink assignment can show up in the Surf dialog box. If you select a
parent component to surf on and it carries a catalog assignment that references
a Weblink value, it displays in the surf selection dialog box along with the
other related component references. Double-clicking the Weblink reference
launches your browser or appropriate application.
NOTE Picking on a child component to initialize in the Surf dialog box will not
display a Weblink referenced by a related parent. You must pick on the parent
carrying the catalog assignment.
WDBLKNAM assignment
The WDBLKNAM value filters the symbol names that display in the Parts
catalog dialog box. The Symbol Name Filtering option on the Parts Catalog
dialog box suppresses what data displays when a catalog lookup is run for a
particular component. If you perform a catalog lookup on a symbol with block
name “HTD1_xxx” and the Symbol Name Filtering option is selected, the only
records that display are those 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 your symbol’s block name. For example, performing 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 of the 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 example
above, 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 “$$” and any other suffix to make the block name
unique. AutoCAD Electrical’s catalog lookup sees the “$$” and assumes
that this and anything after it is ignored. It treats your symbol as if the
block name were just the basic name of “VTD1F.”
