Why adaptive sketches can not be shered for extrusion?

[kmeldfreyssinet]

Hi,

I wonder why it is like that so adaptive sketches can not be shared?

In my particular case I have I-beam and connection plate in assembly. In connection plate there are holes for bolts and slot.

I wanted to make set of holes in I-beam and cut identical slot.

So I had made a sketch on I-beams' web and projected connection plate. So far so good.

But after I make holes basing on centers from sketch and share this sketch I can no use it for extrusion.

Why? I believe this worked in previous versions.

Cris.
