What is a purpose of a guide curve when doing a swept in SW and why can't I dimension a profile when doing a swept?

When I try to do a swept using a guide curve and my profile is a circle. When I try to give a dimension to a circle an error appears. Why.

The Purpose of a guide curve is to allow the user to change the wdith/height of the sweep easily. Say you want a 1in circle to expand to a 2in radius about halfway in, you would use a guide curve to accomplish this, the guide curve essentially allows the sweep to change to fit your need.

As to the error you are getting this could be caused by many different things and would require a screenshot/error message to resolve. Hope this help! :)
