I'm playing with the custom property builder and I'd like to be able to select a property that would in turn, insert an external block or external object.
For example, I have blocks for different notes. I'd like to be able to pick the note from the list and have the block automatically inserted at a defined location on the drawing. Another example, we have mm and inch formats. But it would be nice to be able to select that option in the custom properties tab and then the correct tolerance block would be inserted.
Is this possible without API?
