How to flatten a conical blended wall??

[Bigadz]

Hi all


I have created my conical shellthrough a blended wall operationin sheetmetal and now I want to create the flat pattern.


When I go to flatten it asks me to select plane/edge to remain fixed while unbending. I have tried to select planes but it isnt having it.


I managed to flatten conical items which were not extruded through 360degrees. From this I was able to select the trajectory edge where the two had not quite met.


Obviously there isnt this edge to select on a full conical shell through so does anyone know how I can get around this properly without having to create a very very small cut and then selecting the edge???


Many thanks in advance, would be a life saver!

After creating theconical shell. go to insert/shape/rip regular rip, create rip line at any side plane of the shell. then create the flat pattern by selcting the rip edge.

Bigadz,


I am curious on how you created your shell? My company is just getting started in PRO/E and we manufacture conical shells for refuelers. I am having the same situation but I can not get the rip to work on my shell drawing. I am probably creating the shell in a way that PRO/E does not like.


Any help would be great. And thanks in advance.
