   HELLO ALL YOU CAD LOVERS,
I HAVE BEEN USING AUTOCAD FOR 20+ YEARS, 2D AND 3D, BUT MY 3D ABILITIES ARE VERY LIMITED TO, REGION, EXTRUDE, UNION, SLICE, SUBTRACT, AND A COUPLE MORE SIMPLE COMMANDS.  ALL THESE YEARS THESE BASIC COMMANDS HAVE SUITED ME WELL, BUT I KNOW I NEED TO LEARN SOME MORE, LIKE SURFACE.......

HERE IS MY OBJECTIVE.  I AM DESIGNING THIS CIGAR POST ASHTRAY STAND, AND I NEED TO PUT A BAND AROUND THE CIGAR.  IN 2D THE BAND LOOKS LIKE THIS ( THE SECOND  PICTURE) THE CIGAR IS 6 CENTIMETERS IN DIAMETER, BUT DIMENSIONS AREN'T IMPORTANT AT THE MOMENT.  I WANT THIS BAND TO GO AROUND A 3D ROD WHICH REPRESENTS THE CIGAR.  FROM A SIDE VIEW I WANT THE BAND TO BE THICK, LIKE SAY 1 MILLIMETER. 

THIS IS WHAT I HAVE SO FAR, AS YOU CAN SEE THE ELLIPSE PART OF THE BAND SHOULD BE SMOOTH FLOWING AROUND THE CIGAR WITH THE REST OF THE BAND

THE GRAPHIC ON THE BAND IS NOT IMPORTANT AT THIS POINT, ALL I WANT TO DO IS PUT A SMOOTH FLOWING BAND AROUND THE CIGAR, WITH THICKNESS AS LIKE IN MY SAMPLES
WHO OUT THERE CAN SHOW ME THE BEST AND EASIEST WAY TO ACHIEVE THIS.

THANK YOU

ERIC

	Is other words you want the elliptical portion of the band to fit the curve of the cigar. Is that correct?

	Is this kind of what you had in mind? Forget for the moment that we're talking about a cigar band. The following is for demonstration purposes only.

	Another view. The basic concept was based upon extruding an ellipse then slicing off the front and back. In the examples shown I did not slice off the front so it was flush with the band. You however would. Edited by John Connor - 17.Jan.2017 at 12:22

	YES, THAT IS PRETTY GOOD!! THE ELLIPTICAL PORTION DOESN'T HAVE TO BE QUITE SO THICK, BUT THE WAY THAT THE BAND FOLLOWS THE CURVE AROUND THE POST IS EXACTLY WHAT I AM AFTER. WHAT COMMANDS DO YOU USE TO DO THIS? IM SURE IF I PLAYED AROUND WITH IT LONG ENOUGH AND WITH TRIAL AND ERROR I COULD PROBABLY ACHIEVE IT, BUT KNOWING AUTOCAD, THERE IS A VERY SIMPLE WAY TO DO THIS, AM I RIGHT? SO HOW DID YOU DO IT? I WOULD GREATLY APPRECIATE THE ENLIGHTENMENT, IF YOU WOULDN'T MIND. THANK YOU ERIC

	Yes, my band is thick but like I previously said this was meant for demonstration purposes only. Your results may vary. Here is what the band looks like with the elliptical portion cut flush with the band. I used the SLICE command with the Surface option. An extruded arc was my slicing surface for the front.

	YES!!! THIS IS EXACTLY WHAT I WANT? I HAVE NO IDEA HOW TO SLICE WITH SURFACE OPTION. IN FACT, I HAVE NEVER USED THE SURFACE COMMAND, OR EVEN WORKED WITH SURFACES AT ALL AND I DID NOT KNOW YOU COULD SLICE ON A CURVE

	Show me where I said I used a command called SURFACE. I didn't. I said I used the SLICE command which if you look at the command line has the following options. Specify start point of slicing plane or [planar Object/Surface/Zaxis/View/XY/YZ/ZX/3points] <3points>: You can "slice on a curve" by extruding an arc. A line or an arc that is extruded YIELDS a surface. The surface is an object that can be used to slice another surface or a solid.

	A simple demonstration. The red arrow is pointing to the arc that ends up getting extruded. Visual style = 2Dwireframe.

	Same demonstration only this time I changed the color of the arc to green and the visual style to conceptual.
