This question relates to corridor meshes and how they relate to corridor processing (performance).
I understand that a corridor mesh - being displayed - is a function of the design stage (as set within the DGNLIB). Such as when the design stage is changed from "design" (no corridor mesh is displayed) to "final" (corridor mesh is displayed).
NOT displaying a corridor mesh, within the current corridor modeling file, increases (or at least) helps with performance. My question has to do with changing the design stage BACK from "final" to "design". The mesh 'display' does, in fact, go away (it is not displayed in the Default-3D model/view). However, the level, used by the mesh element, is still populated and showing usage (Level Manager).
So, is the corridor performance tied to the DISPLAY of the corridor mesh or the fact that it exists (or existed) at some point?
It does not seem possible that selection of the mesh element, for deletion, works. Basically, it does not delete. I guess it is tied to the corridor model itself in some way. Maybe I am missing something(?).
