Summary: When using real world coordinates in millimetres there are issues with alignment of the mouse and crosshair. Normally larger than 5cm on the screen.

Description: When using real world coordinates with millimetres the coordinates get very large and AutoCad doesn't calculate the mouse position correctly when in a 3D rotated view. It makes selection and drawing very difficult when modelling. A typical coordinate is E. 319,000,000 N. 5,811,500,000 when using millimetres, which when using Plant 3D you need to use or imperial. A work around is to truncate the model closer to 0,0 but this causes issues when collaboration between multiple people are required and keeping things in world coordinates is ideal.

I'm hoping that Autodesk can improve the way the mouse position is calculated to fix this issue. It could just be a 32bit stack overflow or something similar.
Within Plant 3D there are other issues that are caused by the large coordinates but my hope is that this fix may fix those also.
