Brent, I found your video very helpful but wanted to point out one item for newcomers to this functionality... The order of defining attributes will determine the order of the attributes in the Edit Attributes list, toward the end of your video (3:00 mark), which can be confusing for data entry since the first attribute created is placed at the bottom of the list and the second attribute is at the top. This is now opposite of what the Callout looks like and I found if the operation is reversed, where the Sheet Number attribute is defined first, then the list is in the same order as the Callout and data entry is much more straightforward. However, please note... The Detail Sheet Number text used to make the block will need to be moved down from the line dividing the circle, before the block is created to place the text the same distance below the line as the Detail Number text is above the line.
