Structures
The definition of a Structure.
What is something built to support loads and resist forces?
The definition of Load.
What are the forces acting on a structure?
The definition of Pictorial Drawings.
What are 2D representations of 3D objects used to communicate spatial relationships and form?
The four types of Pictorial Drawings.
What are Orthographic Projections, Axonometric Drawings, Oblique Drawings, and Perspective Drawings?
The commands that allows you to repeat your last command.
What are spacebar, enter, and left-click?
The definition of Equilibrium.
What is the state when all the external forces acting on a rigid body form a system of forces equivalent to zero or are referred to as balanced?
The difference between a dead load and live load with examples of each.
What is the permanent, stationary weight of a building's structure and fixed components (like walls, floors, roofs, beams, columns) versus the temporary, movable weight that can change over time (like people, furniture, vehicles, movable equipment)?
The meaning of "Orthographic" with its three most common types of projections
What are perpendicular view and front, top, and side?
The definition of Profile.
What is an outline of something as seen from one side?
The command and shortcut key that allows similar objects to form a single, unbroken object.
What are Join and J.
The three Types of Stress and each of their definitions.
What are Compression (Pushes materials together), Tension (Pulls materials apart), and Shear (Refers to a force that acts parallel to the surface of a material or structural element, rather than perpendicular)?
The definition of beams, joists, and girders.
What are horizontal members carrying loads, small, horizontal structural members that supports floors or ceilings by spanning between larger supports, and large, main horizontal structural beams that support smaller beams or joists (a primary load-carrying element)?
The definition of Picture Plane.
What is an imaginary flat surface between the viewer’s eye and the object being drawn, onto which the 3D object is projected to create a 2D representation?
The types of axonometric drawings with their definitions.
-Isometric: equal angles, 120° apart
-Dimetric: two axes equally inclined
-Trimetric: all different angles
The command and shortcut key that breaks a compound object into its component objects.
What are Explode and X?
The definition of Trusses.
What is a triangular framework that distributes forces efficiently?
Four Benefits of Structural Cores with their corresponding explanations.
Stability (Resists wind and seismic forces), Efficiency (Centralizes services like stairs, elevators, restrooms, etc.), Safety (Provides protected escape routes), and Design Freedom (Allows open floor plans around the core).
What is Cabinet being half depth, Cavalier being full depth, and 30° or 45° ?
What is the point in space, usually located on the horizon, where parallel lines appear to converge in perspective drawing to create a view? What is 1-One Point, 2-Two Point, 3-Three point?
The command and shortcut key that creates multiple copies of objects in a pattern.
What is Array and AR?
The reason why triangular arrangement produces stable geometry.
What is triangular units being inherently rigid, meaning they maintain their shape under load?
A three part explanation of how forces are distributed in a truss.
What are the fact that loads are distributed into a combination of tension and compression, are applied at the joints only, and forces of action and reaction on a joint must be equal and opposite?
The definition of Scale and Proportion.
What is the ratio between the drawn size and real size of an object and the relationship of sizes between parts of a form or between a part and the whole, often expressed as a ratio or visual comparison?
The definition of horizon line and the number of vanishing points on the horizon line of a three point perspective.
What are a horizontal line at the viewer's eye level that serves as a guide for creating the illusion of depth and 2?
The command that automatically controls the following settings and modes when drawing:
What is ISODRAFT?
