The

situation: I have been using Rhino3 for years, but it drives me mad

sometimes with solids problems. I’ll describe one here:

I

start with 2 valid closed solids. They need to join, but one

tube-like solid must leave a hole in the union. . I start with an

intersect, but I get: “Objects do not intersect. Nothing done.”

That’s crap I can plainly see they DO intersect. So I ask for a

curves from objects>intersection. I get nine intersections and

they look like closed curves to me. So I explode the lot, then have

the surfaces cut each other and join the remainder to a solid. As

expected I get a bunch of unjoined edges as rhino does not cut

exactly. When I try to merge them Rhino says “This edge is already

merged.”. When I attempt to Join 2 naked edges, Rhino returns: “

Unable to find overlapping intervals.” Result I wasted lots of

time and no idea where to go next. Sigh.

So

my question to the forum: are these problems solved with Rhino5? Or

should I go look elsewhere?

Thanks,

Maarten
