How to Select multiple objects at Once in AutoCAD

Short Answer

Use SELECT or a crossing/window selection to select multiple objects at once in AutoCAD. The most common professional method is to start a command like MOVE, then drag a selection window from left to right or right to left to capture several objects quickly. This does not select objects on locked layers for editing.

What You Need to Know Before

Warning: Selection direction matters in AutoCAD. A left-to-right window selects only objects fully inside the box, while a right-to-left crossing window selects anything the box touches, which often grabs extra objects by mistake.

How to Select Multiple Objects at Once

• Command: SELECT

• Shortcut: SELECT

• Quick Steps:

  1. On the Ribbon, start a common edit command like Home tab > Modify panel > Move, or type SELECT and press Enter.
  2. Click in a blank area and drag:
     • left to right for a Window selection
     • right to left for a Crossing selection
  3. Release the mouse, then press Enter to confirm the selection set if needed.

• Turn selection cycling off if overlapping objects make picking slow, or leave it on when you need to choose between stacked objects.

Variables & Settings

• System Variable: PICKADD (Default: 2)

• Expert Setting: PICKADD controls whether newly selected objects are added to the current selection set. In professional workflows, keeping it at 2 lets you keep selecting multiple objects without losing the previous selection.

Why it Fails

• Cause 1 (Geometry): The selection window direction is wrong, so objects are missed or too many are included.
• Cause 2 (Layers/Locks): Objects on locked layers can still appear selected but cannot be modified by many editing commands.
• Cause 3 (Command/Logic): You are still inside an active command option or subcommand, so AutoCAD is not accepting a new multiple-object selection properly.

Quick Fix & Best Practice

• Quick Fix: Set PICKADD to 2, then use a right-to-left crossing window only where needed to avoid selecting unwanted geometry.
• Manager’s Verdict: For daily production work, use window and crossing selection as the fastest standard method. Avoid manual one-by-one picking unless the drawing is dense or highly overlapped.

FAQ

How do I add more objects to an existing selection in AutoCAD?

Hold Shift to remove objects, or keep selecting normally when PICKADD is set correctly.

What is the difference between Window and Crossing in AutoCAD?

Window selects only objects fully inside the box, while Crossing selects all objects touched by the box.

Can I select multiple objects before starting a command?

Yes, if noun/verb selection is enabled, you can preselect objects and then start the edit command.
