https://forums.autodesk.com/t5/inventor-forum/complex-square-to-round/m-p/5637348#M375728 <P>Its helpful Carlos and I appreciate it.</P><P>Unfortunately there are design criteria that I don't think I can over come.</P><P>&nbsp;</P><P>1.) The transition attach to the main cylinder needs to be tangent (so&nbsp;inpingement on the process&nbsp;is reduced.) We also&nbsp;need to fabricate (unfold) off the file drawing.</P><P>2.) The Main Cylinder Needs to be a variable and still be tangent, because we have like items, or as a result of emperical information feed back from our process which these cyclones will be installed in our plant.</P><P>3.) I would like it to be a fabricated part where we can unfold it.</P><P>&nbsp;</P><P>I am going to look at it,..... when I'm a fresh.</P><P>&nbsp;</P><P>&nbsp;</P><P>If I pick something up I missed, I'll let you know.</P><P>&nbsp;</P><P>Thanks,</P> Fri, 15 May 2015 18:42:27 GMT shaberli 2015-05-15T18:42:27Z
