AutoCAD Basics
The primary area where you create and edit the actual geometry of your drawing at a 1:1 ratio.
What is Model Space?
The command that removes unwanted portions of an object.
What is the TRIM command?
These are used to organize drawing objects by function or location, allowing users to control visibility, color, and linetype across a project.
What are layers?
This type of standard dimension measures the straight-line distance between two points along either the horizontal or vertical axis only.
What is a Linear dimension?
Pressing this specific key on your keyboard will instantly cancel out of any active AutoCAD command and return you to a blank command line.
What is the Escape key (or ESC)?
The feature that allows you to precisely snap to endpoints, midpoints, centers, and other geometric locations.
What are Object Snaps?
The command that creates a parallel copy of an existing object at a prescribed distance.
What is the OFFSET command?
Doing this to a layer prevents any objects on it from being modified or selected, though they remain fully visible on the screen.
What is locking a layer?
This specific type of dimension is used when measuring a slanted line, forcing the dimension line to run perfectly parallel to the angle of the object being measured.
What is an Aligned dimension?
This environment, toggled via tabs at the bottom of the screen, represents your physical paper sheet where you arrange title blocks, scales, and views for printing.
What is Paper Space (or Layout Space)?
The coordinate system you should use if you're drawing a line starting from a known point and moving exactly 6" right and 4" upward.
What is the Relative Coordinate system?
The command that creates a duplicate of an object while leaving the original object in place.
What is the COPY command?
Unlike turning a layer "Off", performing this action drastically improves performance because AutoCAD completely stops rendering the objects in the system memory.
What is freezing a layer?
In technical drafting, this method involves stacking a series of parallel dimensions that are all measured from the exact same starting datum or reference line.
What is baseline dimensioning?
Double-clicking inside one of these windows in Paper Space opens a direct portal into Model Space, allowing you to pan, zoom, and adjust the scale of your drawing geometry.
What is a Layout Viewport?
The symbol you would see on the drawing's File Tab if the drawing was opened in "Read-Only".
What is a lock?
The command that would be useful if you needed to create a symmetrical half of a mechanical part.
What is the MIRROR command?
This specific property setting ensures that an object automatically adopts the color, linetype, or lineweight of whatever layer it is currently placed on.
What is ByLayer?
This critical property setting allows annotations and dimensions to automatically scale themselves to match the scale of the layout viewport they are displayed in.
What is Annotative?
To instantly repeat your very last command or action without typing it out or clicking a button, you can press either of these two large keys on your keyboard.
What are the Spacebar or Enter keys?
To enter a relative polar coordinate in AutoCAD, you must precede the distance and angle with this specific symbol.
What is the @ (at) symbol? (e.g., @5<45)
The command you would use if you have lines that should meet at a rounded corner.
What is the FILLET command?
This command allows you to copy the color, layer, linetype, and other characteristics of a selected source object and apply them instantly to one or more destination objects.
What is MATCHPROP (Match Properties)?
Accessible via the DIMSTYLE command, this is the specific tab where a CAD manager sets global parameters to enforce drafting guidelines like ISO-25 or ANSI for text fonts, arrow styles, and precision.
What is the Dimension Style Manager?
This advanced type of block contains custom parameters and actions, allowing a single block definition to change shape, size, or configuration dynamically on the fly.
What is a Dynamic Block?
