AutoCAD commands list
Reference pages for the AutoCAD commands drafters use every day: the shortcut, exact prompt sequence, a worked example in real project units, and the mistakes that cost the most time.
Draw
Modify
- TRIMTR
Shortens objects back to a cutting edge. Since AutoCAD 2021 the default Quick mode uses every visible object as a potential cutting edge.
Creates a parallel copy of a line, polyline, arc or circle at a set distance. The backbone of wall, kerb and setback drafting.
Joins two objects with an arc of a given radius. With radius 0 it makes a sharp corner, which is the fastest way to close two overshooting lines.
Annotate
Fills a closed area with a pattern or solid fill. Used for material indication in sections, plans and details.
- DIMDIM
A single dimensioning command that picks the right dimension type from what you hover: linear, aligned, angular, radius or diameter.
Places multi-line paragraph text inside a bounding width, with in-place formatting, bullets and fields.
Organise
- LAYERLA
Opens the Layer Properties Manager, where layers are created, coloured, assigned lineweights and plot styles, and locked, frozen or turned off.
- XREFXR
Attaches external drawings as references so shared backgrounds stay in one file. The core of multi-discipline coordination in AutoCAD.
Combines objects into a reusable named definition placed with INSERT. Edits to the definition update every instance.
Housekeeping
- PURGEPU
Removes unused blocks, layers, linetypes, text styles and other named objects, shrinking the file and cleaning imported junk.
