Weaverbird grasshopper download5/10/2023 ![]() ‘Loft’ all these curves to create a surface. 20 points is much more sensible than 279!) Split the base curve into two halves such that all lines are open curves and form a series of arches. You should now have roughly recreated the 3D shape of the dome. Use ‘Project’ to project these lines up to the surface of the original model. In top view, manually draw a series of guidelines (‘Curve’) in the same plane as the extracted edge curve. In hindsight, the methodology presented below certainly isn’t the most efficient or effective, but the important thing (as is usually the case in engineering) is that it got the job done! The problem was that the model we received was nothing more than a collection of lines arranged into one grid pattern and lots of little mesh faces between these lines – no NURBS surfaces or anything else nice to work with! The challenge was therefore threefold: recreate the NURBS surface, manipulate the surface into a structurally more efficient form (think lots of non-zero Gaussian curvature) and then apply a range of grids to it. We had received a domed roof from the architect, and we had been asked to optimise the form and experiment with different gridding options. Something I’ve found in my archives – one of the first projects I did when starting my EngD in 2013.
