Hi Jean-Michel,

Thanks for your post - Stardraw Design 7's data specification calls for input/output stubs to be horizontal.

Connection points are created dynamically where a horizontal cyan line meets the red outline of the symbol. Vertical IOs cannot be used to create connection points.

I understand that this may not be the answer that you were hoping for, but the behavior you've described is 'by design' - SD7 is not intended to support vertical inputs or outputs.

Kind regards,
