Hi BlueBeam,
I found that I am unable to snap to a markup line during manual alignment of documents in the Overlay Documents command. One of my contributors omitted the grid lines from the drawing set they marked up. I need to extend wall lines to intersect with other geometry so I can align my drawings. I added markup lines to snap to but find that even with the Snap to Markup option selected it doesn't snap to markup in the manual alignment window.
