Selection Cycling does NOT activate while creating feature lines if another drawing is xrefed in

[ewinkler3RXYE]

IN Civl3D (2023) I am trying to create some feature lines to represent the finished AC grades at the face of curb in a parking lot.  I have the site plan xrefed in the drawing and I am drawing feature lines by elevation and by grade over the top of the linework.  When I snap to the end of feature line, Selection Cycling does NOT activate, and it defaults to the end of line in the Xfer drawing with a zero elevation.  I want it to snap to the end of the feature line.  I have tried during Selection Cycling on and off, DRAWORDER to move things to the back or front, changing the LEGACYCTRLPICK values.  Nothing works.  I end up freezing the Xref layer and turning it back on when I need it.

So far, I only have this problem with Selection Cycling when creating a feature line trying to start a new one from an endpoint or vertex of an existing feature line that coincides with an endpoint to a line in an Xref drawing.

I would suggest creating multiple viewports and having one in isometric view for this specific reason.  That way you always know what you are snapping too when using features or anything else with an elevation.  Plus you wouldn't have to toggle on/off your basemap and you have a dedicated view of just your 3d model/surface:

Selection Cycling doesn't work with OSnaps. Not even with simple lines. I use the method suggested by @v-silvestre .
