I am trying to draw a simple circular spring via using "swept boss/base" function. I am doing exactly same thing which you can see in below link;

designLOG • Tutorial: Solidworks curved helix [advanced]

if i summarize it first i open a sketch to front plane ,draw a circle and close the sketch , then i pass to right plane open a new sketch a draw a line and close sketch again. When i try to use swept function with try to use straight line as "profile" and circle as a "path" it gives me this error and i can't draw a turning circle spring.Can you help me what i am doing wrong?

Best Regards
