Surface modelling advice
Surface modelling advice
(OP)
Attached is a very simple model created using surfaces. Using NX4, what would be the best approach to model dome at the end to give the highest possible quality surface continuity.
Many thanks in advance.

Life shouldn't be measured by the number of breaths you take, but by the number of times when it's taken away...

RE: Surface modelling advice
In this case it really doesn't affect the middle of the surface so greatly as to be of any concern whatsoever, but the surface approaches the POINT the internals go astray and while the continuity condition for the edges is met the shape is slightly affected. Here I have just trimmed it back and thrown in a through curves surface to get a technically smoother result.
Comparisons between mine and Johns show s surface change of .05mm and about one degree. Other than for a highly polished item these kinds of differences might well go unnoticed.

After a while you learn how to quarter things up into trimmed oversize sheets and basically rectangular surfaces.
