osnap only snapping to "top" of object

[toonamo]

in earlier versions of autocad osnap used to snap to all endpoints if i had it enabled. Now osnap only snaps to endpoints that would be visiable if the object was solid. If a endpoint is "through", underneath, or inside a object. I am unable to snap to it.

 

I am using autocad 2015 does anyone know where the setting is to toggle this behavior?

Most likely, it's because Dynamic UCS (UCSDETECT) is enabled, which effectively limits OSnaps to those that are on the face or surface that's being selected.

Try setting the variable CULLINGOBJ to 0.
