Hi Yannick - it looks like your object is awkwardly placed relative to Rhino’s world space but not complicated - do you know anything about it other than the point scan? Radius, thickness?
Hi Yannick - the part looks like a section of a torus, most likely, so if you know say, the outer diameter of that torus - looks like about 644 mm, then you’re basically done…
It’s correct. I see that I can create a torus along a curve (by defining the start and end diameter).
So I ‘just’ have to create a curve passing through the center of the torus, and then I will have the outer and inner diameters.
But how can extract the central torus curve?
Or did you have another approach in mind?
Hi Yannick - I think in Rhino you will need to carefully ‘eyeball’ where the central plane of the torus is - then you can look at the points in plan and make a reasaonable guess (Circle > 3Points, or Circle>FitToPoints for example with Point Osnap and Project on) to get the outer circle of the torus. That is what I did anyway…
I achieved to create a volume from the torus point cloud by warping 2 surfaces (on both sides) of the torus. The problem is however, that it creates like a suture on the projection plane (see attached).
So how can I create an outer surface that exactly reflects the variation of the point cloud on the whole circumference? (warp is here not the appropriated method).
