Unbending pipes in S/M not impossible

While mucking around doing some RF cabling (don'town Routed Systems) I wondered if there was a way of modelling bent round cables that could be unbent using sheetmetal functionality as opposed to modelling a straight pipeand using spinal bend to fold it up. I found I could.


To make it more of a challenge I tried to make it hollow so I could unbend a pipe bent in 3 dimensions.Quite abit harder but yes it can be done.


This is the bent pipe with the unbend feature supressed

This is the straight pipe with the unbend feature resumed.

I have shown the model tree as a really bighint of how I did it but you have to know how tofool Pro/E to be able to shell the sheetmetal part to complete this challenge.


Anyone elsefound a way of doing this??


Will post the model once you have had a chance to tear your hair out

This little trick will be usefull for unbending pipe.

thanks.

SO POST THE MODEL PLEASE

Model of pipe should be in the following link

However I should warn you the shelling of a sheetmetal part is not straight forward.

Dell_Boy:
I don

Pipe is great provided you have straight sections between your semi-circular arcs which don't exceed 180

Dell_Boy:
OK, you are right.


I think your method is good only when you need create drawing with unbend part. There are some profiles what need this (L, U, Z,
