Holes not recognised in rolled sheet when flattened?

I have a cylinder with a series of fittings in it.

I want a flat plate with all the holes already in the cylinder, so it can be sent for rolling and when finished all the holes are in the correct place.

I made a sheet metal cylinder/ barrel drawn with centre point arc, and made into sheet metal as base flange

I then place the barrel in position with mates on the current assembly and then edited it in the assembly.

The editing I did was to sketch a hole over the fitting, dimension it and the cut extrude, up to next.

Once completed I open up the part with all the holes extruded through, and it flattens ok with all the holes.

But when it becomes a drawing the holes will not dimension

and when I convert to a DWG again the holes are not recognised as circles

Would be grateful if someone could help
