Hammer.RenderMapViewHUD gets the actual mapview as well Simple Trace API for tracing against map worlds in Hammer HandleIndex.RegisterHandle can defer to IToolsDll Give mapdoc nodes managed handles so we can use them safely, move all the interop from hammer -> tools since they're not Hammer exclusive they'd be in an invalid interop state when used elsewhere... Although this might also not work because of linking, need to play around more.
