I would like one end to be smaller. thank you.
you can taper it with using loft instead of sweep. To make a loft you have to sketch the 2nd profile.
Another solution could be using sweep with path and guide curve. Pierce the profile on both curves and don‘t add the dimension for the with. When both curves change the distance to each other, the profile will follow and change it‘s size.
Depends on the expected result...
How can I attach a file to a forum post?
You can add guide curves to tape swept feature - see below image
But I recommend you using loft feature as others mentioned here
Don't use sweep with guide curve. It offers too much control over your geometry. The last the you want is a model that is exactly what you need.
