First thing to do is make sure you have the Custom Properties in either the Part or the Drawing
Then in the sheet of the Drawing r-click on the sheet and Edit Sheet Format. From here you can then add notes and link them to the properties in either the drawing or the part.
For this example I have added a note and manually written Print Issued By: - I have then clicked on linked to property. I can then either pick the current document if that property is defined in the drawing or model if it is in the part document. I can then pick any of the custom properties from the drop down list.
This note will then be linked to whatever you put in the Custom property box. Then make sure to exit the Sheet Format mode in the drawing, save the sheet format and finally save the drawing template / part template so those Custom properties that you require to be input are in the Drawing and Part templates to be filled out and populated to the drawing sheet.
A recommendation - I would set all the Custom Properties to something generic like "xxx" when saving the template so this value shows up in the drawing sheet and you know that it requires an input.
Of course if you already have templates with the Custom Properties available all you have to do is link them in the Drawing and make sure to save this Sheet Format and Template.
I hope this helps Matthew
You have to create the properties in Property Tab builder (either for part or drawing) and then link that properties in drawing sheet.
$PRPSHEET: refers to the properties from part and $PRP: from drawing
Once you set up your property tab builder, it's easy to link all these properties
To see a little behind the scenes right click on the drawing page and go to Edit Sheet - there you can see the drawing template setup..
Follow John George's advice - he was a big help for me a few years ago and Custom Properties is where it all starts....
