I am having trouble creating a clean offset of a complex surface.
The base surface is created as a network surface, which I then used Kangaroo to get a nice smooth form
I am now trying to offset the surface inward to have a consistent 600mm gap between the two.
I have got as far as manually creating a second inner surface, which now has a pretty consistent distance when measuring from outside edge to inside edge, although I am having difficulties making that distance consistently 600mm all over.
I have tried dividing both surfaces into the same # of points, draw lines between them, use line SDL to create 600mm lines, rebuild surface from endpoints. The problem with this is I couldn’t get a clean result.
The design intent is to have the inner surface offset inwards (when viewed in plan) and to have the base/stem that runs vertically to be more or less the same as the outer srf.
No. I think @maje90 meant that if the curvature radius is less than 600mm (as illustrated below = 500 mm) then going inward along the surface normal (the red arrows), the normals cross over, meaning that a surface cannot be built intersecting itself (or whatever that would be called). Like so:
