Parametric Room Label
This family tutorial will teach you some cool stuff about nested families and parameters and also save you a ton of time if you ever need to label room sizes.
We teach you how to nest an annotative family in a model family, link it up the local parameters and tie it all together with reference planes that result in downstrean shape handles at the project level.
Once the family is loaded into the project you can 'align and / or lock' the nested / controlling reference planes to walls or parallel edges and the room size label updates . Use the 'align tool' or select the family and use the shape handles.
* The lessons learned here on nesting an annotation family within a model family and being able to nudge or move 'the annotation' part of the model family at the project level is NOT widespread knowledge.
Below is an embedded playlist with 1 CADclip demonstrating the family in action and 3 more CADclips showing you how to build the family yourself from scratch.
