I have a project in Maine. I am using the new projection, NAD83 Maine CS2000 Central (EPSG:3554), for my Coordinate Reference System (CRS). I have imported shape files from Maine GIS that are in WGS 84/ UTM zone 19N. When I create a new shapefile in 3554, and proceed to create a new feature, whenever I snap on a line from a layer in UTM, the vertex shoots off into the north pole or some other hinterland. I have checked my transformations which seem ok. What setting do I have wrong? I am working in 3.18 on a Mac.
Is your project (File, Project Properties) in the same projection?

I was thinking about this - What projection is your map canvas? I'll try to test here but it sounds like something maybe set to degrees vs feet or meters.

First, there are raster images in the Project. Maine GIS orthophotography (EPSG:26919) - NAD83 / UTM zone 19N
The Project CRS (map canvas) is (EPSG:3554) which is the same as the Layer (shapefile) (EPSG:3554) being edited, although there are other layers that are used to snap to that are (EPSG:4326) WGS84 and (EPSG:32619) WGS 84/UTM zone 19N. The errors occur when I snap on to a layer feature that is in WGS 84. I like the degree/meter/feet suggestion. I will work on that.
Plus I have some GPS generated data with different projections because the state of Maine cors and various survey companies use different coordinate reference systems and RTK systems.
By the way, this happens with some of my projects in Massachusetts as well, so it is not just a Maine issue.
Thank you all,

I seem to have resolved it. I removed all the transformations for the Project except one which is Destination CRS EPSG:3554 with No Source CRS. Now the snapping works fine when snapping to “All Layers”. I can now trace etc to layers of different projections.
Thanks everyone.
