AutoCAD files. Unlike AutoCAD objects, proxy graphics have no intelligence.

purlin A longitudinal structural member in a roof. Purlins support the loads from the roof deck or sheathing.
They are supported by the principal rafters or building walls (or both).
In Revit Architecture, when you use the Beam tool to add beams between joists, the structural usage of the
beams is automatically set to purlin, and their display within the plan view adjusts accordingly. In the
following floor plan, the dotted lines indicate purlins placed along the midpoints of the joists.

pushpin A user-placed control that provides a quick way to allow or prevent changes to the position of an
element. After you place a pushpin, you cannot move the element until you unpin it by clicking the pushpin
control. See Preventing Elements from Moving
