do you have the "system options -> Drawings -> Allow auto-updated when opening drawings" checked?
I do now, but isnt that the same thing as saying "yes" to if you "want to update the drawings" when you open the document in the first place?
Also, wouldn't it be the same effect as rebuilding (CTRL+Q) at the beginning?
I noticed that
right-clicking the view => show/hide => show hidden edges
is available and choosing the option ends up displaying the part consistent with the pre-set configuration (without notches).
is there an option or anything that will toggle hidden edges from a drawing view upon opening the file?
The problem feature is the notching at the end of the parts.
That notching is governed by one feature being suppressed and unsuppressed.
I managed to edit the files in a bunch of places while maintaining the error.
I was able to edit all feature names, all planes' names that are in-use, all custom properties, etc.
I "lose" the error when editing the part file's un-used planes.
I have a set of maybe 15 reference planes that I have put into a folder and is there for future use (they are currently not being used at all and are just hanging around with zero significant ties to anything in the file).
They are currently unsuppressed and when I suppress any one of them, the error disappears on the Drawing file.
