Yes in this case that is correct and that is what I wanted to pay attention to as well.
For the same reason when using turntable and the same object is rotation you going lose the sharpness on the edges since the edges moving to the 30 degrees position , that why I proposed the vertical position to eliminate this issue to minimum .
The 30 degrees of the object angle can also create the “wood” effect on the scanned model edges since it can’t calculate the massuments properly.
