IGES assembly not displaying

[Skie]

Using Pro/E 5 Wildfire
I saved an assembly as IGES (.igs) with all the parts using the "save as copy" method.
To test to see if the machinist will be able to open it, I tried to open the main assembly file (as an assembly) and there is nothing displayed in the main window and the parts of the assembly are not listed in the file tree. I heard that the model could be tiny if there is a unit difference but I can not zoom in and find anything. I've tried all sorts of different settings in the open file options window but nothing is working. The following is some screen shots:

Try...
Select ASM_Front
Right click Redefine --> Uncheckthe "Adjust
Display" in the Display TAB.
Repeat for other three planes and regen.
The display should now adjust to the maximum size of the
model with a Zoom Extents.
Good Luck.

I've found that IGES (and other import) files tend to come
in with extra layers that put the entire model on a layer
and hide it. Check your layers, I bet you find that the
geometry is on a hidden layer.
