We are glad to introduce Manis, a collaborative design tool for timber plate structures with wood-wood connections. This grasshopper plugin, developed by Nicolas Rogeau, Ph.D. student at IBOIS, EPFL, and NCCR Digital Fabrication, allows generating joints geometry, fabrication toolpath, and robot trajectories. The solver enables users to specify modular assembly sequences, and accordingly compute compatible vectors of insertion for each module. Furthermore, Manis includes a numerical simulation component, developed by Aryan Rezaei Rad, for the structural analysis of such construction systems. The algorithm is based on COMPAS – an open-source framework developed at the Block Research Group and NCCR Digital Fabrication – for streamlined data post-processing, visualization, and Finite Element Analysis.
