+| Revolution geometry. The 3D surface is generated by revolving the profile defined by points for example $a$--$b$--$c$--$d$ around the vertical axis. These points form the generating curve of the solid, precomputed to create smooth filled quad strips. |
 The **Revolution 1.0** model generates a 3D solid or surface by revolving a 2D **profile** around a specified axis. This is ideal for turned or **axisymmetric parts** (vases, domes, bases, circular panels). The generating curve is defined in the **''paths''** array and is interpreted in the plane orthogonal to the chosen axis.
