I totally empathize with the confusion. The use of properties is awesome when populating BOMs and Drawing formats but taking the time to understand the ins and outs of linking what-to-what can be daunting. Properties can belong to your Model (such as the description, weight, P/N and appropriately Revision number), to your sheet (Company name -if you offer services and have different clients that you detail for, date drawn, by, etc.), views (bubble callouts, BOMs, weldment tables) or the current document.
One has a few property prefixes to learn-
...if the property starts with.... SW evaluates it from.....
$PRP The current document
$PRPSHEET The default model view set in the Sheet Properties (likely the vw. of the model you just dropped in the dwg.)
$PRPVIEW The view (duh!)
$PRPMODEL The model (2xduh!)
What's weird is that when you set the custom property 'description' in the model- $PRPMODEL is not the property prefix you see in the annotation or text link on your drawing format. It's actually $PRPSHEET:"Description".
If you went through the trouble of creating a custom property named 'Description' for your drawing (in addition to the one created in your model) and you have 'Current document' selected in the 'Link to Property' dialog, picking 'Description' from the drop-down will not be the same 'Description' you set in your model properties list. If it's blank, your linked text will not update.
Now that your eyes are totally glazed over, try this;
right click the text you've assigned to link to on your drawing, select 'Edit Text in Window'. If you see $PRP:"Description" change the $PRP portion to $PRPSHEET. Be careful not to add any spaces or delete any quote marks.
Alternately delete the entire entry, ok it then re-select the text box (should still be there), hit the link-to-property button in the Text Format box on the left, click the 'Model in view specified in sheet properties' radio button and use the 'Description' there from the dropdown.
You should have the correct 'Description' property you set up in your model.
Moral of the story; you don't need to create 2 'Description' properties. You just need to point to the right one. Same for the rev. property or any other you create.
very comprehensive instructions.
I'm still uncler on one thing: I managed to fix the title block, can I save it as a template and reuse it with other sheet formats/templates? Or copy/paste from one template to the next?
And one more: can I update the title block in the existing prints, if not too much hassle?
