Figure 19.52 Lines representing clearance space in a family
Another option for adding clearance spaces to your equipment is to create
unique clearance-space families. These families should be categorized as
mechanical or electrical equipment families, but you could categorize them
as any of the available subcategories, depending on how you want to control
their visibility. In a project file with worksharing enabled, a workset could
be created for equipment clearance spaces, as an option for making it easier
to control the visibility of all equipment in a view. There is a downside to
relying on worksets for visibility control, however, because you may also be
using worksets as an option to load selected parts of the project. This can
lead to confusion, not just within your company's project team but also for
those working collaboratively with you.
Clearance space families can be face-hosted families for easy attachment to
the solid geometry of your equipment families. Consider making individual
familieswiththedimensionsforeachuniquetypeofclearanceorforspecific
types of equipment.
The example of displaying solid geometry (the clearance) with linework
can be applied to most families' solid geometry. Displaying lines instead of
geometry will improve your overall project performance with your families
because Revit will need to regenerate lines instead of surfaces. This can be
especially noticeable for round objects such as pipe connectors and their
extrusions, because the software will try to simplify those round surfaces by
breaking them down to multiple flat surfaces.
