Modelling cone pipe with multiple parts

[1550]

Hello I have one problem.

What is best way to modelling pipe with 3d "centerline"
and with multiple cones.

Im trying to make model of mine motocross bikes exhaust
pipe and i have not figured out how it is most easiest to
make.Im trying to make assembly which i can modify
"centerline" just to drag and drop.
I want also convert those parts into sheet metal and make
unbends about those parts.

this what im modelling (this is some photo of similar
type of pipe)

A swept blend or VSS can achieve what you want. For the Swept Blend use a centerline curve then sketch the appropiate profiles at the required locations. Just make sure all sketches contain the same number of sketch segments.

A VSS controlled via a graph can also be done.

As far as unbending the sheetmetal that is something I have little experience with.

Also add the .com to get the picture links working correctly.

Thanks for reply Jsantangelo

I made some pipes with Swept Blend but how i can measure
line distance when centerline is 3d? For 2 stroke pipe
design that correct centerline lenght and cone angle is
very critical.

What is VSS

That unbending with sheetmetal is quite easily make but i
need to made assembly of all those parts. But it is quite
easy to make.

.COM i dont know why the forum takes of that .com when
using that ready IMG option.
