I really want this feature too, for me; the ability to have the line by line gcode turned into an stl; being that Cura would auto model out each line/layer into an STL would be AMAZING for the ability to render what would appear to be a pre printed object for 2 things:
1: The ability with UE5 to have my games show with Nanite an in game object that appears to be 3D printed
2: Rendering capabilities with raytracing to see what a model would look like being made of different materials after it's been 3D printed.
