32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Template file extension
Drawing templates use the .dwt extension. QNEW creates a drawing from the default template named in Options > Files > Template Settings.
Layer 0 rules
Layer 0 cannot be deleted or renamed. Objects on it inherit block insertion-layer behavior, and it can be frozen, locked, or set non-plotting.
LAYMRG command
LAYMRG merges a source layer into a target layer and deletes the source layer. Objects on the source layer move to the target layer.
Frozen versus off layers
Frozen layers are excluded from regeneration and object snaps. Off layers are still regenerated and can still be snapped to.
Associative hatch behavior
An associative hatch updates when its boundary is edited. A non-associative hatch keeps its original shape regardless of boundary changes.
MTEXT versus TEXT
MTEXT creates paragraph text inside a defined width with inline formatting. TEXT creates single-line or multiline text without an embedded width boundary.
Annotative objects
Annotative objects scale automatically to the annotation scale of the model space view or viewport. They can carry multiple annotation scales.
Multileader style control
MLEADERSTYLE controls arrowhead type, landing length, and text attachment for multileaders. MLEADER combines a leader with text or a block.
ATTSYNC command
ATTSYNC updates all block references after attribute definitions are edited in the block definition. BATTMAN manages attribute order and visibility.
Xref layer naming
Xref layers are prefixed with the xref name and a vertical bar, for example XREF|WALLS. VISRETAIN controls whether layer changes persist across reloads.
Overlay versus attach xref
Overlay xrefs are not carried forward when the host drawing is itself attached as an xref. Attach xrefs are nested into the host.
Binding an xref
XREF BIND converts an xref to a block definition. The Insert option keeps the xref name prefix; the Bind option removes it.
Viewport scale
A paper space viewport's scale is set from the standard scale list or by entering a ratio. VPSCALE reports the current viewport scale.
VPLAYER overrides
VPLAYER changes layer properties per viewport without affecting other viewports or model space. Overrides can be saved in layer states.
CTB versus STB
Plot styles are color-dependent (CTB) or named (STB). A drawing uses one type at a time, set by PSTYLEMODE or the Plot dialog.
PSLTSCALE system variable
PSLTSCALE controls whether linetype scaling is based on paper space units (1) or model space units (0) inside viewports.
DIMASSOC values
DIMASSOC controls dimension associativity: 0 means no associativity, 1 means non-associative, and 2 means associative dimensions.
DIMLFAC usage
DIMLFAC multiplies the measured value for dimensions. A DIMLFAC of 0.5 halves the displayed measurement for scaled geometry.
Tolerance types
Dimension tolerance types include symmetric, deviation, limits, and basic. Upper and lower values and precision are set in DIMSTYLE.
Geometric tolerance frame
TOLERANCE creates feature control frames with symbols for form, orientation, location, and runout, following ASME Y14.5 or ISO conventions.
Window versus crossing
Window selection (left to right) selects only fully enclosed objects. Crossing selection (right to left) selects objects that are touched.
MATCHPROP command
MATCHPROP copies properties from a source object to selected objects. The Properties palette edits common and object-specific properties.
OVERKILL command
OVERKILL removes duplicate and overlapping objects and can merge collinear segments. It reports the number of deleted objects.
Drawing standards file
A .dws file stores layers, dimension styles, linetypes, and text styles. CHECKSTANDARDS reports violations and can fix them.
Sheet set file
A sheet set (.dst) organizes drawings into subsets and sheets. Sheet and custom properties can feed title block fields.
eTransmit purpose
eTransmit packages a drawing with dependent files such as xrefs, fonts, and plot styles, and can create a transmittal report.
DWGCOMPARE command
DWGCOMPARE highlights differences between two revisions of a drawing. The comparison can be saved or exported.
Command alias file
Command aliases are stored in the .pgp file. REINIT reloads the file after edits without restarting the program.
Action macros
Action macros record command sequences for playback. They can be edited and assigned to a toolbar button or command.
Script files
Script files (.scr) run a sequence of commands without user interaction. SCRIPT runs a script for batch plotting or repetitive edits.
Profile file
A profile (.arg) stores support paths, template locations, and plotting settings. It exports and imports a standard workstation configuration.
PURGE command
PURGE removes unused named objects such as layers, blocks, and styles. -PURGE with the All option purges all unused items in one pass.
