How to Draw CURVES AND PIPES on Surfaces!

Inside Of History on Instagram: "A perfect curve and perfect turn on railway tracks are extremely important to ensure smooth, safe, and stable movement of trains. When a train moves at high speed, even a slight imperfection in the track alignment can cause vibration, derailment risk, or uneven wheel wear. The curves are carefully designed with specific radius and superelevation (tilt of the outer rail) to balance the centrifugal force acting on the train. Engineers use precise geometry to mainta
