I am trying to create / update my first boarder, and I have a few questions.
There are several system properties available, where is the best place to find their definitions?
If I want the sheet name on in the title block what property do I have to add to the title block for that?
Assuming you are using Logic, that property (field) would be called "Sheet Name".
The last button on the "schematic editing toolbar" is called Add Field.
Click on it and select the field you want to add. You can even create your own!
