"Model" section of Nastran Model Tree collapsing

"Model" section of Nastran Model Tree collapsing

The "Model" section of the Nastran Model Tree collapses when edits are made within it.  Often, I will run different analyses using a previous analysis as a baseline, so I will duplicate that previous analysis.  This duplicates all of the associated information including creating copies of the Idealizations, Constraints, Loads, Connectors, etc.  This isn't ideal, but it is covered in the following post:  https://forums.autodesk.com/t5/nastran-in-cad-ideas/dont-duplicate-idealizations-loads-with-analysis...

 

If this is done several times, you quickly end up with copies of copies of copies.  The only way I am aware of to undo this is to expand the "Model" section and delete them, then add the original items back to the new study in their place.  However, when dealing with most items in the Model section, this part of the tree collapses when an action is taken.  For instance, if the copy of an idealization is deleted, the Model section of the tree minimizes and has to be re-expanded again for further editing (does not apply when deleting loads, oddly).  The same thing happens if dragging the original item to the new Analysis from the Model section.  This happens constantly and is a hassle.  The functionality is there, but it is inconvenient to have to re-expand this part of the model tree.  This was a new issue with the 2023 releases.

 

The same is true when creating multiple element groups.  Between each group creating, the Model section collapses and must be re-expanded to create an additional group.

 

The ask is to allow the Model section in the Nastran Model Tree to stay expanded unless the user commands it to be collapsed.
