Add a picture to help us understand what you are referring too. I think you are talking about the model tree - placement folder. You can turn off the placement folder in the model tree under tools, tree filters, then unclick the items you don't want to display (placement folder).
Then you can save your model tree settings
Set your filters and then under the settings drop down select Save Settings File. In your config.pro set the mdl_tree_cfg_file option to the file you created.
If my understanding is correct, you speak about Customize Layer UI accessible when clcining Customize checkbox upon >File >Save as >IGES
If you confirm this understanding:
For the eventual question you may have: Is it possible to NOT display Placement/Body and Annotation information in this Customize Layers UI in Creo parametric 7.0 + (and restore what was offered in Creo parametric 6.0-), this is not possible actually. If columns are configurable in this UI, the rows are not (contrarily to Model Tree where they are, via Tree Filters capability).
Your solution of View>Expand only expands one level of the top node.
I am working with many sub-assemblies, so having to expand every sub assembly is time consuming.
The enhancement of additional information is a major hinderance to me. I work with many shared parts within many sub-assemblies.
So I set levels of 20 or so parts by typing the number hitting arrow down and typing the same number. If I Expand All I now need to hit arrow down four times in between every part. Or I have to take the time to expand 30 or so sub assemblies one at a time. I can potentially miss a sub-assembly, causing issues downstream.
Pictures below to clarify for the rest of the group. V6 to V8
I see. I suggest therefore to open a case to PTC Technical Support to discuss this change of behavior between Creo Parametric 6.0 and 7.0 on the Customize Layer UI proposed upon IGES Export process.
This will need further investigation and exchanges with R&D Team to see if we may introduce something which would allow to:
I am trying to open a case with technical support. Creo 7.0 / 8.0 are not on the list of products???
Any way of just pointing technical support to this thread?
