Crane
ADDON. Version 0.2.4. Released on 19-Jul-2020. Provides 38 components. Created by Suto Kai. Features 2 video tutorials.
Crane is a Grasshopper plugin to design origami products. Designing of foldable products with rigid folding motion is difficult for designers, architects, and researchers who are not origami experts. Crane is a powerful tool for not only such people but also origami experts. This software focuses on design, rigid folding simulation, form-finding, and fabrication for origami. Because Crane Solver is a hard constraint solver, it can precisely simulate a rigid folding motion and form-finding with geometrical constraints like Freeform Origami.
Constraints
| Anchor Anchor constraints of between selected vertices and input points. Numbers of both list must be equal. | |
