In the ANSI-large, the default title block in the ANSI drawing template, when i edit the title block i see green lines which might use for aligning text. they disappear when i finish editing. They are on a layer that's: By Standard (title ANSI) The rest of the lines are black and are on the title ANSI layer. What's this By Standard prefix? What are they and how to make them?
My title blocks are loaded with Sketch-only lines to align various text and graphic features. No functional reason that I know of to have title block sketches fully constrained, but it's still good practice.
