Loading full model enables user coordinate system on all parts

[ThomasVelde]

When swapping from express to full, on a large assembly, i experience that UCS appears on all parts. How can i remove this?

And this is the view in express mode:

Those look like Center of Gravity glyphs, not UCS.
You may have to open/activate EVERY subcomponent (part and assembly) under your main assembly and unselect "Center of Gravity" under the View Tab:

You can use the following iLogic code in your main assembly to remove all of those in subcomponents:

Dim oDoc As Document = ThisApplication.ActiveDocument
Dim cmd As ButtonDefinition = ThisApplication.CommandManager.ControlDefinitions.Item("AppCenterOfGravityCmd")
If cmd.Pressed Then cmd.Execute
For Each aDoc As Document In oDoc.AllReferencedDocuments
     Dim bDoc As Document = ThisApplication.Documents.Open(aDoc.FullFileName, False)
     cmd = ThisApplication.CommandManager.ControlDefinitions.Item("AppCenterOfGravityCmd")
     If cmd.Pressed Then cmd.Execute
     bDoc.Save()
     bDoc.Close()
Next

EDIT:

If you are using Inventor 2018, consider updating the software to fix a known bug that causes the same issue:

Thank you! I will try the code, and hope it saves me from changing them all manually

Update: I got some errors when running the ilogic rule, but the icons disappeared and everything looks good. Thank you for helping me out 🙂
