Thin sweep features can be a little deceiving. A swept thin does not behave the same as an extruded thin. With an extruded thin, you can have open contours in the sketch. With a swept thin, the profile must remain closed.
Note: For all these examples, the “pink” sketch will be used as the path, the “green” as the profile.
This first example might be what you would expect a swept thin to be used for.
With the sketches set up something like so…
Unfortunately, this is not the case.
In order to create a sweep like this, the profile must be closed…
So what is a swept thin used for? Basically, it is nothing more than a shell. It just happens to be built into the sweep feature.
Solid Sweep… Thin Sweep…
