Is a .dwt File Different From a .dwg file in AutoCAD?

Short Answer

Yes — a .dwt file is different from a .dwg file in AutoCAD. A DWT is a drawing template used to start new files with preset layers, styles, and units, while a DWG is the actual working drawing file. The most common method is using QNEW or New from a template. A DWT is not meant for normal production drafting.

What You Need to Know Before

Warning: Editing a .dwt template carelessly can affect every new drawing created from it, including wrong units, title blocks, layers, or plot settings. A common failure is users saving live project geometry into the template by mistake, which then appears in all future drawings.

How to Create or Use a DWT Template in AutoCAD

  • Command: QNEW

  • Shortcut: CTRL+N

  • Quick Steps:

    1. In the Quick Access Toolbar, click New, or press Ctrl+N to start a drawing from the default template.
    2. If needed, use Application Menu > New > Drawing and choose a specific .dwt template file.
    3. In the template, confirm settings like annotation Scale, units, layers, text styles, and plot setup before saving project work as a .dwg.

Variables & Settings

  • System Variable: QNEW (Default: varies by installation/template path)

  • Expert Setting: This setting controls which default template file AutoCAD uses when you run QNEW or press Ctrl+N. If it points to the wrong DWT, every new drawing can start with incorrect standards, units, or title block content.

Why it Fails

  • Cause 1 (Geometry): The template contains unwanted model geometry, title block errors, or outdated annotation objects, so every new drawing starts wrong.
  • Cause 2 (Layers/Locks): Required layers in the DWT may be frozen, locked, or set to incorrect colors/linetypes, causing drafting and plotting issues in new DWGs.
  • Cause 3 (Command/Logic): Users open a DWT and work in it directly instead of creating a new DWG from it, then overwrite the office standard template.

Quick Fix & Best Practice

  • Quick Fix: Use SAVEAS and select *AutoCAD Drawing Template (.dwt) only for clean standards files; use normal DWG** format for active project drawings.
  • Manager’s Verdict: Use DWT files for company standards, startup layers, sheet setups, and styles. Avoid using DWT as a live project file — production work should always be saved and managed as DWG.

FAQ

Can I convert a DWG file into a DWT file?

Yes, use SAVEAS and choose the DWT file type.

Can AutoCAD open a DWT file like a normal drawing?

Yes, but it should normally be used as a template, not as the active production file.

Does a DWT file contain layers and text styles?

Yes, a DWT can store layers, dimension styles, text styles, layouts, and plot settings.
