There is an easy method to quickly apply your own preset graphic overrides to linked models independent of the host view settings.
1. Create a dummy project and create a view template within this project with all of the standard overrides that you wish to apply to linked models, including filters.
2. Use "Transfer Project Standards" and check only view templates to transfer this template to the linked model.
3. Duplicate any view in this project. Rename the view "FOR LINKED VIEW" and apply your transferred view template to this view. Save the linked model and close.
4. Open your host model and make sure the linked model is re-loaded to apply the recent changes.
5. In the view settings for the host view template, go to 'V/G Overrides RVT Links" and click on the Display Settings where it says "By Host View". Click on the circle for "By linked view". In the dropdown list, find "FOR LINKED VIEW" and apply.
6. Repeat step 5 for any host view templates with links.
That should do it. With this method, you only need to setup your overrides and filters once. It is also easy to make slight modifications to the overrides by simply switching to "Custom". If there is a case where you do not have direct access to consultant models, I suppose you could simply ask the consultant to apply steps 2 & 3 after transferring them the dummy project.
