Solid fill not displaying in viewport?

[ChuckEdwards]

I'm finding a problem with solid fill, drawn in model space its fine, but viewed through a viewport and all I see is the outline of it in wireframe.

Any suggestions as to why this might be the case?

I'm not having this problem on other drawings, it's limited to this file, but a colleague has also had as well it so not my workstation. This narrows it down to this specific drawing being the problem.

As regards variables, FILL = 1, FILLMODE=1.

It is just solid objects with the problem, polylines with a width display OK as does fill text.

Unlock the viewport and change UCS to World, Plan Current.

Thats it.

The XAxis of the other viewport in the original drawing was slightly off in Z...must have been it, the new viewport I'd created for this was taking the properties of that and thus not displaying correctly.

Grrrr, some of my colleagues are really bad when it comes to setting up drawings.
