Let us see one more interesting option in loft. So, here I have a path and along the path I have created some cross sections using plain a long path option. And here in the last option I have selected all these paths. Now, you can see here I have a closed option in the dialog box. So, when I click that the first cross section and the last cross section are joined. So, this is an interesting option.

Sometimes this might not be possible, if they please do not permit to join the first and the last cross section.
