Hi All,

SW2019 for some reason rebuilds the entire tree of my models on open.  I have models with 1-3k features in them.  I also have models from SW 2017 (we skipped a version when upgrading) that rebuild on open and blow up.  This is an incredibly annoying behavior that did not exist in SW2017 and is a major problem for me.  

I know that there is a "suspend rebuild" option for assemblies and it does affect parts as well.  But setting that option to "never" does nothing- the models still rebuild on open.  Setting that option to "prompt" is worse since it rebuilds first then asks me if i want to rebuild the model and if i say yes then it rebuilds again.  

Freezebar is an option i guess... but it doesn't help me with my previous models.  I would have to "fix" the model and then enable freezebar.  And i really don't want to go through that process.  

Anyone got any tricks? Thanks in advance.
