How to start a new drawing from scratch in AutoCAD?

Short Answer

To start a new drawing from scratch in AutoCAD, use the NEW command and choose a standard template such as acad.dwt or acadiso.dwt. This is the fastest and most common professional method because it starts a clean file with basic settings already loaded. Limitation: a truly blank drawing still depends on the selected template defaults.

What You Need to Know Before

Warning: If you start a new drawing from the wrong template, your units, annotation scale, layers, and dimension styles may already be incorrect before you draw anything. This often causes plotting and scaling errors later, especially when working between imperial and metric projects.

How to Start a New Drawing from Scratch in AutoCAD

• Command: NEW

• Shortcut: Ctrl+N

• Quick Steps:

  1. Press Ctrl+N or go to the Application Menu > New > Drawing.
  2. In the Select Template dialog, choose acad.dwt for imperial or acadiso.dwt for metric.
  3. Click Open, then verify starting settings such as Model tab, UNITS, and annotation scale before drawing.

Variables & Settings

• System Variable: STARTUP (Default: 0)

• Expert Setting: STARTUP controls how AutoCAD handles creating or opening drawings at startup. If set differently in some environments, the New Drawing workflow may show a startup dialog or behave differently than expected, which can slow down standard template-based drafting.

Why it Fails

• Cause 1 (Geometry): The new drawing opens with the wrong unit base, so objects are created at incorrect real-world size from the start.

• Cause 2 (Layers/Locks): The selected template contains preloaded layers that are locked, off, or set to non-plot, which blocks normal drafting.

• Cause 3 (Command/Logic): Users expect “from scratch” to mean no template, but AutoCAD normally creates new drawings from a DWT file, so inherited settings still apply.

Quick Fix & Best Practice

• Quick Fix: Run UNITS immediately after NEW and confirm the correct unit type and insertion scale before creating geometry.

• Manager’s Verdict: Use NEW with a company-approved template for production work, and only use default acad.dwt or acadiso.dwt for simple drafting or testing. This avoids standards drift and reduces setup errors.

FAQ

Can I create a new AutoCAD drawing without a template?

Not in normal workflow; AutoCAD typically creates new drawings from a DWT template.

Which template should I choose in AutoCAD?

Use acad.dwt for imperial drawings and acadiso.dwt for metric drawings.

What should I check first after starting a new drawing?

Check UNITS, current layer, annotation scale, and plot-related settings.
