Snapping / Locking / Layers in Wishlist - Feature and Content Requests Posted February 8, 2016 This is similar to some of the requests I've seen in here, but not quite ... I think there could be two more columns in Layer Navigation: Lock and Snap Lock would make it so nothing in that layer could be modified until the layer is unlocked. Snap (which is really "No-Snap Override" in my mind) makes it so that even if "Snap" is on as the general mode, some layers would still not snap. Particularly useful when a drawing contains a DWG that has tons of vertices that you need to see, but don't want to snap to, and you need to snap to other things. As a workaround, I've even gone to making a PDF, importing it (with snapping turned off on the PDF), and using it to draw; but it makes the file big, so I delete the PDF after drawing.
