It's a bit hard to tell from your description (more precise questions
result in more precise answers), but the message is probably pretty much
JUST AS IT SOUNDS. Let's say that the projected path of the loft, or
any guide path you're using, has a severe curve or twist in it . . .
pulling your profiles along the inside of the severe portion of the path
can result one or more profiles intersecting it/themselves as it/they
is/are swept along. SolidWorks says that's a boo-boo. It's the same
for sweeps as it is for lofts. Another possibility is that the vertices
you're using to transition from one profile to the next are not
analogous -- maybe you're not watching which points you are choosing.
Watch the preview with the highlighted path between the vertices
chosen. You need to select a vertex in each profile that is going to
give you the result you want. Extreme transitions (especially extreme
twists) can result in just such an error message.
One method of solving the type of problem you're encountering is to use
a guide curve, or even two guide curves, instead of merely relying on
the profiles to align the loft properly. As others have pointed out,
you REALLY need to do the tutorials that come with the software. I know
it may seem like time you just don't have at the moment, but how much
time are you losing when you encounter problems like the ones you've
been describing in your posts?
