Since Grasshopper doesn’t have a special component to create geodesics on meshes (only on surfaces), the making-up of this task was undertaken on Python. For the Grasshopper definition we used Anemone plugin, special for loops creation in Grasshopper. We may see the plugin workflow through two main components (Purple groups), the start and the end of the Loop. In the views the blue lines correspond to the shortest curves and closest to a geodesic.
