slope An angled surface (such as a roof or ramp), or the angle at which the surface rises.
See Roof Slope on page 684, Sloped Ceilings on page 720, and Ramps on page 742.
slope arrow A user interface mechanism that defines the slope of a roof, floor, or ceiling plane, using a line
in the direction of the slope.
Use a slope arrow when you know the height at the top and bottom of the object s plane rather than the
slope. For example, slope arrows can be used to adjust a flat roof to satisfy a particular height at a drainage
point. See Slope Arrow on page 685.
snap (1) To jump to a line or reference point in a drawing.
snap (2) A line or reference point to which Revit Architecture will jump when you are placing a component
or sketching a line.
When you place a model element or sketch a line in a drawing, Revit Architecture displays snap points and
snap lines to assist in aligning elements or lines with existing geometry. Snap points display in the drawing
area as triangles, squares, and diamonds, depending on the snap type. Snap lines display as dashed lines in
the drawing area.
For example, when you move the cursor over an existing wall to draw a new wall, Revit Architecture displays
a snap line (a dashed line at the center line of the wall) and a snap point (purple triangle at the midpoint
of the wall). Click a snap point or snap line to start drawing the new wall from that location. For more
information, see Snaps on page 503.
soffit The exposed underside of an architectural element.
On a roof, the soffit is the underside of an overhanging roof eave. See Roof Soffits on page 694.
solar study A photorealistic image of a building model used to evaluate the impact of natural light and
shadows on the buildings and site.
For more information, see Solar Studies on page 1241.
