AutoCAD Modify Commands: The Complete Guide
Introduction
AutoCAD’s Modify commands are the editing tools that allow you to refine, adjust, and clean up your drawings. From removing unwanted geometry with ERASE to reshaping corners with FILLET, these commands are the backbone of efficient drafting. Every professional AutoCAD workflow depends on them.
This page lists all of the Modify commands currently available on CAD Master Coach. Each command includes a short explanation and links to detailed tutorials so you can learn step by step.
Break
Cut objects into separate pieces with BREAK. Learn pick points, specify gaps, and common use cases.
Chamfer
Create beveled edges at intersections. Distances, angles, trim options, and best‑practice settings.
Copy
Duplicate geometry efficiently using COPY. Base points, multiple copies, displacement, and shortcuts.
Erase
Master the AutoCAD ERASE command to delete objects, clean drawings, and improve productivity. Learn selection methods, shortcuts, mistakes to avoid, and pro tips.
Explode
Turn blocks, polylines, or hatches into constituent objects. When to use—and when to avoid—EXPLODE.
Extend
Extend lines and arcs to target edges with precision. Boundary selection, modes, and tricks.
Fillet
Add arc fillets between objects. Radius control, trim settings, multi‑fillet workflows.
Join
Combine lines, arcs, or polylines into single objects with JOIN. Tolerances and cleanup tips.
MatchProp
Copy layers, colors, linetypes, and more using MATCHPROP. Filters and productivity tips.
Mirror
Create mirrored copies across an axis. Erase original options, precision setup, and examples.
Move
Relocate objects by base point and displacement. OSNAP strategies and selection methods.
Offset
Make parallel copies at exact distances. Side selection, erase source, and pitfalls to avoid.
Pedit
Edit polylines: join, fit, spline, vertex, width changes, and conversion from lines/arcs.
Rotate
Rotate entities around a base point to precise angles. Reference options and best practices.
Scale
Scale objects by factor or reference. Maintain proportions and avoid common scale mistakes.
Trim
Trim objects back to edges quickly. Quick mode vs. classic, selection strategies, and tips.
Frequently Asked Questions
They are the tools used to edit, move, reshape, or delete existing objects in a drawing.
It’s technically a Modify command but is often used to create new geometry from existing objects.
They are in the Home tab of the ribbon, under the Modify panel.
