How to Avoid the Need for a RATINGx ‘Cheat Sheet’

Filed under: Electrical — nateholt @ 12:49 pm

For customizing your schematic/panel symbols, there is a big advantage to using the 12 RATINGx attributes supported by AutoCAD Electrical (named RATING1 through RATING12) instead of creating your own named attributes.

  • RATINGx attribute values can automatically migrate from schematic to panel representations
  • RATINGx attribute value are available to be included in the dozens of standard AutoCAD Electrical reports

But it’s not all tinsel and glitter. The disadvantage is that you have to remember which RATINGx attribute is used for what value. And you may even need to take into consideration the component’s “family”… that you want to use RATING1 on a power circuit breaker symbol for “Interrupting Rating” and then reuse RATING1 on a power factor correction capacitor for “KVAR Rating”. You end up needing a cheat sheet to keep things straight when you’re making the RATINGx assignments for a given symbol type!

How to reduce need for a ‘RATINGx’ Cheat Sheet

When you create your symbols and add RATINGx attribute definitions, do this:  Enter a description in the “Prompt” edit box. That’s it!

Now, when you insert/edit one of these components and display the Rating View/Edit dialog, the symbol’s prompt values will show up in the dialog display for each rating edit box. No more guessing. No more need for the cheat sheet.

Example

Here is the power circuit breaker symbol with nine RATINGx attribute definitions (all set to be “invisible”). Each is set up with a prompt value that represents what that rating value is to mean.

Inserting / Editing instances of this revised symbol now shows which rating is which for this type of symbol…

Suggestions

  • Figure out which RATINGx attributes will have a common usage across most or all symbol families. In the example above, Rating2-5 will be common to most symbols.
  • RATING1 is used by AutoCAD Electrical for cable “core/color” assignment. So it is recommended that if you reuse RATING1, chose something that would never need to assigned to a cable. In the example above, “Interrupting rating” reuses RATING1… a value that would probably not be assigned to a cable — so there is no conflict.
