I am having a hard time working with radial geometry: arcs, etc. for a concept design. I need to try different things, scales, widths, angles but I am finding it extremely inflexible and cumbersome.
For example: What could be the easiest way to go from the blue shape to the light blue shape? I was not able to achieve it with any command and I opted for redrawing the arcs with curves and creating a new surface.
Not sure why there is no ExtendSrf with Arc option… or offset and edge from a surface. That would be really usefull
It also would be really nice to set the Gumball to always point towards a center, in that way i can easily move objects towards or away.
Or to permanently set it at a fixed location for all objects. That way I can always rotate from the same fixed point.
It looks like you are creating boundary curves, and then using PlanarSrf to create a surface within the curves. That results in trimmed surfaces.
Try using Revolve to create the surfaces using a line along one straight edge as the curve to revolve. That will create untrimmed surfaces with isocurves being radial lines and circumferential arcs.
For some rather subtle reasons, arcs/circles can be a bit odd to deal with, and so part of your problem is created by that. I’d suggest making an oversized “master” surface - think of a record - little hole in the middle - just by lofting two circles together. Then, instead of extending, Split them by Isocurve in either direction to get the interactive editing you’re looking for. Way better in this particular case to reduce in size from one big surface than extend a smaller one.
Or play with radii and angles to your heart’s content in Grasshopper and bake the result when you are happy. Change your mind? Delete a surface and bake a new one. WedgeMaker.gh (22.1 KB)
