Issues with object display get worse with distancefrom origin

I’m seeing a problem where graphical hidden line removal is getting worse with the object’s distance from the origin. See the two examples below. The first is an object, 500mm tall, located at the origin. The second is the same object, moved aproximately 500 metres from the origin. as you can see, the hidden line removal algorithm is failing miserably. I’m an architect, and routinely work with large sites, and this kind of issue makes for a lot of visual confusion. I posted a while back on a related topic - where the rendering engine was failing with objects located away from the origin when the skylight was enabled (Rendered view problems vary with object location (skylight issue))
