I'm an OBD user but I have been told that this behaviour/functionality is inherited from Microstation, so I post this idea here.
When creating a drawing - I use the "Drawing production" tools from OBD - there is a big difference in behaviour for cached vs Dynamic representation of the reference.
Very specifically I want to see object fill colour also in Cached representation. See as reference this forum thread https://communities.bentley.com/products/building/building_analysis___design/f/aecosim-speedikon-forum/227775/odb-drawing-production---filled-colour-on-faces
Right now the only way to achieve it is to use Dynamic representation + display rules. The result is a very "slow" drawing.
