Hi, I want to see how the G-Code model geometry compares with the original STL imported model, is this possible? This is useful to understand in advance how much the actual printed model will deviate from the original design. For example, an overlay of the G-Code model on top of the STL model would be very useful. When I switch views from standard to Preview, the zoom factor changes, so there is no possibility to even take a screen capture and overlay them in Photoshop. Any tips?

Also, a related question, on the attached image (front view), which red line represents the original STL model? The outer, the middle (average) or the inner? Thanks.
