Creating a conical extrusion

Creating a conical extrusion

Creating a conical extrusion

(OP)
I have a profile that I want the end to tmper down by 30%.  The general shape of the feature is circular.  I am trying to add the taper to the end.  The feature is basically a thin walled tube with a 15% opening.  I have tried the protrude with a draft, which isn't correct, and doesn't work.  Any suggestions from the experts out there.  
Thanks in advance.

RE: Creating a conical extrusion

Without seeing your actual geometry, here are a few things to try.

A) Extrude a cylinder, chamfer the one end, and then use thin wall.

B) If it has a cylindrical axis, create a revolved protrusion and have your taper built into the profile.

C) Try creating a loft.

One of the above 3 methods should work for you.

RE: Creating a conical extrusion

Hi,

another solution might be:

- sketch on x/z plane --> circle with OD of small side
- parallel plane to x/z plane with distance = tube length
- sketch on that new plane  --> circle with OD of wide side
  center should be that of small circle
  
- sketch on y/z plane --> line from mid small to mid big circle
  (seen as vertical lines)

-- function --> swept surface
   --> multiple path an cross sections
   
   --> select the line that connects both circles
   --> accept
   --> NEXT
   --> select both circles
   --> preview
   --> select open ends
   --> finish
   
-- function --> Thicken
   -- select the just created surface
   --> key in the wall thicknes (distance)
   --> direction --> either inward or outward
   --> finish
   
-- possible --> hide all sketches/surfaces

drawback: the tube is somewhat 'bottle-shaped'
