For me the code to attach is working, and from what I can tell the keyin to activate the GCS to all views is work for me. Try adding your coordinate system name to the acs activate all command. e.g. acs activate all VT83F
If this does not resolve the issue, would it be possible to provide a (small) sample design file, a screen shot of what is you are expecting to see - even if done manually, and a screen shot of what you are getting programmatically after performing a "acs activate all"? That along with Product Version(s) may help us track the issue down more precisely.
