Hi everyone,

I am trying to redo a part from a 2D drawing.
It is a connection on a vessel (cylinder) to weld a flange.
The last operation required two chamfers on the shell (Cf. left corner of the drawing). it is impossible for me to achieve it even with different functions.

Please find the drawing, for the 3D model the forum tell me that the type of file is not conform.

Thank you everyone
