Reference callout with callout tag
reference line A line used when designing families of model elements or placing elements in a building
model. When you draw a reference line in a view, the line is visible in other, related views.
A straight reference line provides 2 planes to sketch on. One plane is parallel to the work plane of the line
itself, and the second is perpendicular to that plane. Both planes go through the reference line.
The following image shows a selected reference line (and its reference planes) in multiple views. For more
information, see Reference Lines on page 346 and General Rules for Geometry Creation on page 344.
reference plane A 2-dimensional plane used when designing families of model elements or placing elements
in a building model.
See also reference line on page 1444. For more information, see Reference Planes on page 1046.
reference point A point in the current view that you can use for positioning or dimensioning a model
element. When you move the cursor near a reference point, Revit Architecture displays a temporary dimension
between the element being placed and the reference point. To display different reference points, press TAB.
When you are creating a family and you use a reference plane with the Is Reference property turned on, the
reference plane can be used as a reference point for dimensions. For more information, see Is Reference
Values on page 345.
