Can I create a ʼLinear Arrayʼ (multiple copies) with one command in SketchUp?

Short Answer

Yes — in SketchUp, you can create a linear array of multiple copies in one workflow by using Move with the Copy modifier, then typing a multiplier like x5 or /5. This is the most common professional method for a SketchUp linear array. Limitation: it works best on grouped or component geometry.

What You Need to Know Before

Warning: If you array raw geometry instead of a group or component, new copies can stick to surrounding faces and edges, causing unwanted merging. A very common failure is entering the spacing value incorrectly after the first copy, which produces the wrong count or distance distribution.

How to Create a Linear Array in SketchUp

• Command: Move

• Shortcut: M

• Quick Steps:

  1. Select the object, then make it a Group or Component first if needed (Right-click > Make Group or Make Component).
  2. Activate Move from the toolbar or press M, then tap Ctrl (Windows) or Option (Mac) to toggle Copy mode.
  3. Place the first copy in the desired direction, then type x[number] for multiple copies at the same spacing (example: x6) or /[number] to divide the total distance evenly, and press Enter.

Variables & Settings

• Key Setting: Copy modifier toggle in the Move tool
  This toggle controls whether Move relocates the original object or creates copies. In professional workflows, confirming the small copy cursor indicator before placing the first duplicate helps avoid replacing the source object by mistake.

Why it Fails

• Cause 1 (Geometry): The object is loose geometry, so copied edges and faces merge with nearby geometry and break the intended array.
• Cause 2 (layers/Locks): The object or target context is locked, or you are editing inside the wrong group/component context.
• Cause 3 (Command/Logic): The array syntax is entered at the wrong time; x5 or /5 only works correctly after the first copy is placed.

Quick Fix & Best Practice

• Quick Fix: Convert the selection to a Group, use Move in Copy mode, place one correct copy, then type xN or /N immediately in the Measurements box.
• Manager’s Verdict: Use this method for fast, controlled 1D repetition in SketchUp. For clean models and easier edits, professionals usually array components instead of raw geometry.

FAQ

Can I set an exact spacing for a linear array in SketchUp?

Yes — place the first copy at the correct distance, then use xN to repeat that spacing.

Can I divide a total length into equal copies?

Yes — after placing the first copy at the end distance, type /N to distribute copies evenly.

Is there a dedicated array command in SketchUp?

No — the standard professional method uses the Move tool with Copy mode and typed array syntax.
