I was wondering if there was a way to adjust the distance that the camera 'penetrates' the object. I tend to work in scales of millimetres rather than the default metres. It seems that whenever I zoom in to check detail, the camera goes into the object to view the blue polys, and I can't see the orange polys close up to check details.
In the attributes manager's menu, click on "Mode" and select "Project"
On the "Project Settings" quick tab near the bottom you will see a "View Clipping" option. Set this to 'small' or 'tiny' or twirl open the attribute to review manual controls and set the value for "Near" to whatever you need.
