good afternoon all,

Thanks for the incredibly fast reply's  !! it's working now i had to make the gap 1 degree otherwise it's to small like kelvin said.

Now I have solved one problem a other problem occures :S and because I'm not very familiar with the sheet metal module i cant solve this problem either (shame on me).

On the hole i create i want to make a tube with a inner diameter of 100mm  and height of 300mm on the hole in the cone.

But what's wise to do make a seperate sheetmetal part with on the bottom of the tube the same contour of the cone.

Or make a multibody sheet-metal part ? if it's the last methode i found http://help.solidworks.com/2011/English/SolidWorks/sldworks/AllContent/SolidWorks/Core/Sheet_Metal/c_Multi-body_sm_parts.htm?id=bc09a2e9e0b5416795117fc55b1a9009#Pg0

But i dont really understand how to do it. if somebody can give me some guiding, i'm very graceful !

Greetings,

Peter
