What are some problems with pictorials? correct answersthe distortion of angles, the distortion of true
lengths, the distortion of Internal measurements, the distortion of curves
Then the general rule for presenting the object becomes: correct answers"Start with the preferred
configuration; then add or subtract whatever views are necessary to best show all of the geometry."
