How to draw CYLINDRICAL HELIX || Engineering drawing | technical drawing

An astroidal helix surface is a three-dimensional shape formed by combining two elegant mathematical ideas: the astroid and the helix. An astroid is a star-shaped curve with four pointed corners, created when a smaller circle rolls inside a larger one. If you imagine that star shape moving upward while twisting around an invisible central axis like a spiral staircase, the path it sweeps out forms the astroidal helix surface. The result is a surface that curves and folds in a rhythmically twisted
