taper a solid 90deg pipe fitting?

[Anonymous]

I ve been trying various ways to taper a solid 90 degree pipe fitting
It has to go from a 2.50' dia to a 2' dia.Im at a loss. Ive attached a dwg with the 2d model of the 90 bend.

thanks to all who respond,

You'll probably get a better response posting in the Autocad.drafting NG. But, since I'm here and you are here, I'll try and answer your question. This can't be easily done or probably can't be done at all correctly in standard AutoCAD. What you are trying to do is a loft between two different shapes which AutoCAD has no tools for. You need a program like MDT or Inventor to handle this correctly.

Me
I was able to produce your part in Autodesk Inventor. as stated by others i do not believe this can be done in AutoCad. i was able to export the file to .iges and import into Autocad here it is. hope it helps

I dont think you can do it with solids, but if you wanted to do it with surfaces it can be done using the edgesurf command. You need to set your surftabs fairly high though.

Okay, Here it is as a AutoCAD 3d solid if you can use it.

If the attached image is close to what you want to model then it is not a difficult task at all. Especially for round ends. Could take a little bit of time however.

Cool, would you care to tell us how you did it Igor ? I can do it with surfaces but couldn't figure out how to do it with solids.
