2 stroke pipe - how to unwrap the cones?

[Anonymous]

Hello guys,

I’m designing a two stroke pipe at the moment. Now I got the cones and angles right where I want them to be, but I don’t get how to unwrap them so that I can print them out to try fit or laser them. Some times it works and sometimes don’t. I’d appreciate to get some help from somebody. 
Sorry for my bad English...

I hope this is right

It’s not the full model yet, but I wanted to know if or how it works, so the work isn’t all for nothing

It would have helped if you kept the rules for sheet metal in mind during modeling, but it will certainly work if done correctly.

What do you mean by the rules for sheet metal? I watched your video with the cone, but with „straight“ cones it somehow works for me as well. Only the cones with an angle at the top and the bottom won’t work.

Make conic surface with at least minimal planar surface and then trim the top and/or bottom as needed.

Thank you. I’ll try it tomorrow, but it seams like a plausibel way

I wouldn't mark it as Solved until you actually figure it out for sure.  😜

Haha, sorry I’m new here. Didn’t really know what that button meant to be there😂 so I come back later when it’s really solved👍🏼

You must make sketch of every cone but without end angles just straight cones and then you revolve them in surface menu to 359degrees then you make flange in sheet metal menu but u must have choosen the rule so like sheet metal 0.8mm or whatever u need then you must thicken the cone and select the joint then you make lines where u need angles and then you select that lines and make new angled faces then you make a lot bigger circles on that new faces and last step you extrude that circles like u cut the cone in outside direction but u need to have in mind that you can make cones just one by one

Sheetmetal Lofted flange (Brake Press) and Rip will get you very close.(Quickly)
