Unable to edit definition of global coordinate system

I should be able to edit/modify the global coordinate system (CSYS) when starting a new part.  But when I open the Edit Definition dialog, the Origin and Orientation tabs are greyed out; inaccessible.  I don't understand why.

This is a previous discussion on the default coordinate system.

Stephen, 

Thank you, that's exactly what I was looking for.  It has been a while since I have used Pro/E, and I forgot a few things.  Defining the CSYS the way Sullivan explained makes a lot more sense to me.  

 

Do you have any resources or suggestions for setting my new "default" for my "start parts".  Now that I have done this, I know I can make this a template that I can use every time, but I don't think I ever learned how to do that in Pro/E, so I'm starting from scratch.  Thanks in advance.

Once you have a file(s) saved you like and are happy with your setup, There are some config.pro settings for template files (start parts)

template_solidpart

template_designasm

and others where you set the path and filename for the part/assembly etc.

This question comes up with some frequency. Would you elaborate on why you "need" to change the orientation of the default csys? Your use of the term global csys implies that you may be trying to replicate something from another CAD system in Creo. Doing this may or may not be useful for you.

 

I would suggest you define the problem here and ask for Creo best practices to test out for your scenario.

I didn't say that it was a "need", but it should be possible, regardless of why I want to do it.  The answer to your question is that I'm importing models into a different application where I'm conducting modal analysis.  Orienting the CSYS so that the two programs match is a time-saving step.  In either platform, the problem can be overcome, but it's a matter of not wanting to waste time on either end.  I can always start my model on the appropriate plane so that when it's imported, the features line up correctly with the respective coordinate systems.  In some cases, that would require starting a sketch on the negative top plane, or negative Front plane.  Alternately, in the receiving application, I can turn the model to orient the features to the correct axis.  Again, another step that takes time.  I don't want to have to do either of those extra steps.

 

That said, I have found that Sully7's solution here works perfectly for me: https://community.ptc.com/t5/3D-Part-Assembly-Design/Is-it-possible-to-redefine-default-coordinate-system-and-change/m-p/535601#M69404

Patriot_1776 - love the name, and you're not wrong, the CSYS is definitely 0,0,0.  But that's not the issue.  We aren't talking about moving the CSYS to a new 0,0,0.  It's simply a matter of reorienting the X, Y, Z axis at that 0,0,0 origin so that they have the preferred orientation w.r.t. to the Front, Right, and Top planes.
