Is the ‘Defpoints’ Layer Created by the User or the System in AutoCAD?

Short Answer

No. In AutoCAD, the Defpoints layer is created automatically by the system when you place the first dimension, typically through the DIM command. It is not normally user-created in standard workflows. However, it can be deleted or misused later, which causes confusion.

What You Need to Know Before

Warning: The Defpoints layer is tied to dimension definition points and is often misunderstood as a normal no-plot layer. Using it for regular objects is risky because plotting behavior can vary by setup, and deleting it may affect existing dimensions.

How to Check When Defpoints Is Created

  • Command: DIM

  • Shortcut: DLI, DAL, DAN, or DIM

  • Quick Steps:

    1. On the Ribbon, go to Annotate tab > Dimensions panel and start any standard dimension command.
    2. Pick the geometry and place the dimension in the drawing.
    3. Open layer properties Manager to confirm that Defpoints was created automatically.

  • This is the fastest and most common professional method because Defpoints is typically generated the moment the first dimension is created.

Variables & Settings

  • Key Setting: Plot property in Layer Properties Manager

  • Expert Setting: Do not treat Defpoints as a reliable project no-plot layer. Although it is commonly non-plotting in many workflows, professionals usually create a dedicated no-plot layer instead so plotting standards stay controlled and predictable.

Why it Fails

  • Cause 1 (Geometry): No dimension has been created yet, so AutoCAD has not generated the Defpoints layer.

  • Cause 2 (layers/Locks): The layer may have been deleted, purged, or altered in a template, making users think it was manually created.

  • Cause 3 (Command/Logic): Users often create objects on Defpoints assuming it is a standard utility layer, but it exists for dimension definition points, not normal drafting.

Quick Fix & Best Practice

  • Quick Fix: Run DIM and place a dimension; AutoCAD will recreate Defpoints if it does not already exist.
  • Manager’s Verdict: Let AutoCAD create and manage Defpoints automatically. Do not use it for normal drawing objects; create a dedicated no-plot layer instead for office standards.

FAQ

Can I create the Defpoints layer manually?

Yes, but in normal AutoCAD practice it is system-created when dimensions are added.

Does Defpoints always plot?

Not reliably for workflow standards, so professionals should not use it as a general no-plot layer.

What command usually creates Defpoints first?

A dimension command, most commonly DIM, creates it automatically.
