So, I'm working on a project in which I need to create a wall that has a double curve.  I figured swept blend would be the best option to accomplish this.  However, every single time I try to use the swept blend, the error message "more than one curve not allowed" comes up after drawing the first profile.  I've watched multiple tutorials, and I tried to copy exactly what they did.  I reset the referance plane, and even changed the path to a straight line (instead of the arc I need) but nothing helps.  I keep getting that error message.  Could someone please tell me possibly what I'm doing wrong?  Thank you so much!

A SWEPT BLEND PATH can only have ONE segment !

attached is a sweep blend procedure for multiple sweeps, note that it helps to have workplanes and I use framing elevations which will snap to a "named" workplane only. If you do not name the workplane the framing elevation will not snap to the workplane. this is extremely helpful in getting the correct shape. Generally you do not need a sweep blend if you section does  not change position. For instance in the attached the reason for the sweep "blend" is to change elevations. If the elevations are the same and the section extruded shape does not change then you may as well use a sweep only.

Thank you so much Typhoon and mbsteve for your help.  I figured out what the problem was: I was not clicking on 'Edit Profile', after clicking 'Profile 1', so it was reading my first profile as part of the path, making it multi-segmented.  WWHub- when have I reposted?  This was the first question I have ever posted on this site.  If you are talking about other users' threads about Swept Blend, the questions/answers did not help me in my problem, as the path that I had originally drawn was a single segment (the arc or straight line).  I did not already have an answer, or I would not have asked the question.

I've used a Spline as the path to get bends.
