Lines in MapBuilder do not snap to trails anymore.

Tried to map out Flume + Liberty trail here below:,1008.32429&z=15&b=mbt

The lines would only go in straight and would not align with the trails.
I am used to a different behavior.

    Somehow this ended up in our spam folder, I just found it and looked at that map. It does appear to be behaving funny. Did you get this working at any point or is it an open issue still.

    I'm also seeing this issue. It appears that you can't snap or trace lines that are in the MapBuilder Topo. Is the MapBuilder layer a flattened layer or are the trails actually a separate layer that can be traced? Coming from a GIS background, being able to trace segments or copy & paste trails sections would be RAAAAAAD! I'd pay for that feature...

    This feature is working totally fine for me. Can you tell me what you have your snap-to set to? (Upper right corner of the map). If it's set to "Lines" that is user lines not map lines and you need to change to Map Builder Topo. This is a vector layer so if its on there you can snap to it.

    Benny Mouton's Avatar - This is a link of a map that I am trying to get the software to snap to the trails that are defined with the 7.5' Topo Layer. I have experienced the same problem with the MapBuilder Topo as well. I am using the line tool, but it doesn't want to snap to the trail.

    Good afternoon,
    Just checked and I'm not able to reproduce this issue.

    A few things to double check: make sure you are snapping to the right layer (if you're on MapBuilder Topo you'll want to snap to OSM, USFS Topo, snap to USFS) the selection box is in the top right corner. The other thing to check is that you've zoomed in far enough, we don't snap with very wide zooms (just way too many possible lines to snap to) so ensure you're zoomed far enough in that the lines turn yellow for snap to functionality.

    If neither of those things resolve your issue it is likely related to your machine specifically, just respond here with the OS you are on, the browser you are using, and a sample map of an area you're not able to snap to.

    Kipp -

    We were making some infrastructure changes that temporarily disrupted snap to. It should be back (browser cache refresh might be required).
