As some people have also mentioned in earlier posts, I ended up with a mesh or edges at the centre intersections. I’ve used exact coordinates so I know that the intersections should match up perfectly, however in wireframe view it’s obviously a total mess… pretty though, but not very efficient.
Haven’t been able to come up with a solution as of yet, but this can be cleaned up later once we turn the bezier curve base into mesh.
EDITED:
All good now. In lecture 106 and 107 we generated the mesh object from the curves and did some cleanup. I selected all of the vertices around the centre poles and merged them, them moved them to coordinates (0,0,z). Also made sure to remove doubles.
