BIM Software Tip: Understanding the Directional and Twisting Characteristics of Rhino Surface Features
In Rhino, surfaces are defined by three key characteristics: directionality, distortion, and continuity. These factors are essential for evaluating surface quality.
Directionality refers to the two main directions on a surface, represented by the U and V coordinates. These directions correspond to the surface’s inherent coordinate system, where points, lines, and the surface itself are identified by their UV values.
Distortion occurs due to the forced alignment of surfaces to maintain a certain level of continuity. This necessary adjustment can cause the surface to twist or deform. The tension between achieving smooth continuity and minimizing distortion is inherent and unavoidable in surface modeling.
