And the two ends curve opposite each other like the letter "S"?

Thanks to everyone for the help!
John, yes bulge is tapered and looks like slug. I find the way to draw thiss shape. I draw helix only for one slug, and on ends of helix I draw the small circle and on the centar helix I draw the bigest circle end use Loft command to make a slug shape with helix path. Then I copy slug to the end of the object end switch to the Top view end rotate all slugs with copy option  to the other side of object. Then I use Union command to union the slugs end object.

You could but the real problem would be that it looks like the bulge is tapered at both ends which means that extruding a simple profile (ex. - a circle) along the helix wouldn't give you what is shown in the image you posted.  Your bulge looks like a "slug".

The bulge is tapered is it not?

Too bad the drawing bears no resemblance to the object that is pictured in the first post of this thread.

Hello rdjavi and John, you can find in the CAD/BIM Blocks library the file :
Dywidag.dwg from Vladimir but it's 2D.

The object is cylindrical and bulge is helical only to the longitudinally bulge which runs the entire length and which divides the object into two parts which is why I can not draw simple helix and with swip command draw deired shape.

The "bulge" appears to be helical.  Is it?  Is the object itself cylindrical or tapered?
