Solidbody is been hide when open with ActivateDoc method

Hi all.

I have a program which to open draw and part.

The program do first open draw with openDoc6 then oepn part with ActivateDoc2.

But i found a problem.

If i open a SLDPRT file include cutlist with ActivateDoc method, The cutlist is be hide automatically.

This Picture is that i open SLDPRT file manually.

And please look at this, This is the same file opened with ActivateDoc method.

Also, If i open SLDPRT with OpenDoc6 method, this problem don't occur.

Somebody know about this? please teach me if you know.

Thank you.
