To check for X-ing of the bridge, from which views should the frame be observed?

Explanation:
X-ing the bridge means the bridge is twisted or bent relative to the frame front. To catch that, you need to see the frame from multiple angles. Side views show any tilt or unequal height of the bridge on each side, while a top view reveals twisting across the bridge that could cause the two halves to cross. A front view can hide such twists, and peeking only from the back or along the nose-bridge side won’t reveal misalignment on both sides. So, examining the frame from the sides and from the top gives the full picture of whether the bridge is properly aligned.
