@Mark_Engwirda, while I appreciate the advice and will investigate this method at a later date, for now I would like to understand why this family is not showing in plan.
Below is a screenshot of the plan view of the family in the family editor;

I have ensured plan view is ticked in both the host and nested family, yet still not showing in model space.
Has anybody been able to get this plan view to show in model space?
*Update: I have since discovered that when I select 'Reveal hidden elements', the plan view appears. However, they do not appear highlighted to indicate they are being hidden individually, by a filter or template - see screenshot below.
Does anyone have any suggestions?
