- If all items in a layer are hidden using the tools on the BIM toolbar, then that layer is no longer eligible for selection. To be able to select items in that layer you must use the Layer manager to return the layer to fully visible.

- Any changes you make in the Map files tab of the Layer manager override any filtering actions you make using the BIM toolbar, and will affect the current filter. For example:

  - Tap the icon next to any layer to return the layer to fully visible and selectable.

  - Tap the icon next to any BIM file name to return all layers in the file to fully visible and selectable.
