I am pretty new to Rhino but understand most of the basic building concepts.
I have this image below that someone else created using Rhino and I would like to know how others suggest making such an object. i.e. would it be best to use Sweep1, Sweep2, Loft, Rail Revolve, Extrude with FilletEdge, CageEdit, etc, etc…
I have not been able to figure out a practical method to reproduce this shape. It reminds me of a boat/ship haul but less symmetrical so maybe there is a method being used that I have not tried.
Each of the three raised sections don’t match down their centers so each half suggests separate 2-rail sweeps. They are on a flat base that appears to be offset from the outer rail locations then offset again, dropped a bit, and then perhaps another set of 2-rail sweeps or lofts. Then a little trimming and joining should do the trick.
Sweep2 could work here as JB mentioned but I’d also suggest using Loft as shown with three curves for each mounded area. I drew the simplest three curves first and then used Bend on copies of those before lofting the versions that arc and become asymmetrical.
