Solid working area

Question

In Microstation v8i I have an mdl app called SWA that drew a rectangle (in 2d or a cube in 3d) showing the extent of the solid working area. Does anyone know a way of doing this in Connect? It's really useful for explaining to people why they are having problems with geometry that's way outside the SWA. 
 
 Thanks

 Yes, there can be double precision floating point issues when you are millions of uors away from 0,0,0 that are unrelated to the swa, the swa only applies to breps (smart solids, etc.). 
 The recommended approach is to model near 0,0,0 (uors) and specify a global origin to define the geometry's location in the world. But again, this is just good practice for how numbers are represented, it's not because of the solid extent setting. 
 What you don't want is people changing the swa to 1000 km and thinking, now everything is inside the swa and I'm good to go...because again, the swa is just a scale. It's basically just determining how far apart in uors 2 points need to be to be considered unique, etc.
