Stairs
A tool used to enlarge or reduce selected objects, keeping the proportions of the object the same after scaling
Scale Command
The top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind.
Roof
A void in a wall to allow for windows, doors, or niches.

Sill Height
A tool used to rotate objects by using a base point and providing an indicated angle.
Rotate Command
A circulation element that is a sloped pathway used inside and outside buildings to provide access between vertical levels.
Ramps
A window or multiple windows to display drawing in different scales or show different parts of a building.
Viewport
A block of text, somewhat automated, added to a presentation to provide information on a file.
Title Block

Room Tag
A safety barrier at the edge of a vertical drop or at the edge of stairs to help with vertical movement in a building.
Railing
A set of horizontal planes that control the visibility and display of objects in a plan view.
View Range
