Hi sven,

> Now how to fix them, that is another question.

Well, it kind of depends on what the particular problem is in those areas. You may need to remodel some pieces if they were not built from the same curves or something like that.

Here's a quick kind of example - say I have some profile curves and I do 2 different sweeps along separate rails like this:










You can see that they surfaces kind of generally go in the same direction but there can easily be gaps between pieces if you build them with anything similar to this - to make things touch you would instead need to do something like make sure you use a 2-rail sweep so that the surface will be more controlled on all its sides.

There are also a lot of other ways you can get these kinds of problems, any kind of misalignments, pieces jutting out past some other piece instead of touching, etc... There are so many possible ways to make things that do not touch that I can't really give you a good solution without actually seeing your particular model.
