It’s one of those small behaviors that can quietly waste time. You click the [+] icon next to your drawing tabs expecting a clean template, and AutoCAD opens a large existing project file or the wrong template entirely.
You’re not imagining it. The behavior is tied to how AutoCAD handles QNEW, the NEW command history, and session memory. Once you understand the logic, the fix is straightforward.
The Core Problem: Why the [+] Tab Loads the “Wrong” File
Most users assume the plus sign always opens their default template. In practice, the [+] button follows one of two internal rules:
- It uses the Default Template File Name for QNEW (defined in Options).
- It reuses the last file selected in the NEW command dialog.
If you recently created a drawing using a specific .dwt file — or worse, selected an existing .dwg through the New dialog — AutoCAD may reuse that file reference the next time you hit the plus sign.
That’s why the behavior feels inconsistent. It isn’t random. It’s session-based.
Why This Feels Different in Newer AutoCAD Versions
In more recent releases, AutoCAD introduced smarter session memory for startup behavior. The intent was to reduce repetitive template browsing. In practice, it sometimes overrides expectations.
If a user manually selects a template once, AutoCAD may prioritize that selection over the QNEW default for the remainder of the session — and sometimes across sessions depending on profile state.
For teams working with multiple templates (architectural, mechanical, fabrication, etc.), this becomes noticeable quickly.
The Best Solutions
1. The “Right-Click” Reset Method
This is the fastest way to re-establish the correct template without touching system settings.
Steps:
- Right-click the [+] tab.
- Select New.
- Manually browse to your intended
.dwtfile. - Complete the command normally.
Why this works: You are forcing the NEW command history to register the correct template. From that point forward, the plus sign typically follows that selection.
This method is especially useful when troubleshooting a live production environment.
2. Set the QNEW Default Template Properly
If the issue keeps returning, define the template explicitly.
Steps:
- Type
OPTIONS - Go to the Files tab.
- Expand Template Settings
- Expand Default Template File Name for QNEW
- Click the current path.
- Select Browse
- Choose your primary
.dwtfile. - Click Apply and OK
Make sure:
- The file is actually a
.dwt, not a renamed.dwg - The path is stable (avoid temporary folders or user desktops)
- Network paths are mapped consistently if used in a shared environment
If this path is blank or incorrect, the plus sign behavior becomes unpredictable.
3. Verify STARTMODE and SDI
If tabs are behaving oddly — opening in new windows or disappearing — check these variables:
SDIMust be set to 0 If set to 1, AutoCAD runs in single-document mode and will not support tab behavior correctly.STARTMODESet to 1 to enable the Start tab. Set to 0 to disable it.
Also verify:
FILETABis turned on.- The File Tabs button in the View tab is active.
Advanced Control for CAD Managers
If you’re managing a team, relying on users to set QNEW manually is not sustainable.
Here are stronger controls:
Deploy Profiles with Predefined QNEW
Export a configured profile (.ARG) with the correct template path defined and deploy it across machines.
Control Template Locations
Store company templates in a protected network directory and:
- Add that path under Support File Search Path
- Remove write permissions to prevent accidental modification
Standardize the NEW Workflow
Train users to:
- Avoid using project files inside the NEW dialog
- Never save production drawings as
.dwt - Always start from company-approved templates
Prevent Template Contamination
One of the most common causes of this issue: A user saves a working .dwg as .dwt without cleaning layers, xrefs, or geometry.
That template then becomes the QNEW default.
If users report “Drawing1 already has geometry,” this is usually the cause.
Additional Technical Notes
- The [+] tab and the Start Drawing button both rely on QNEW and command history.
- Workspace changes do not directly affect template selection.
- Corrupted user profiles can sometimes override template paths. If behavior remains erratic, test under a fresh profile.
FAQ: Drawing Tab and Template Behavior
Q: Why does the [+] tab sometimes open “Drawing1” that already contains geometry?
A: Either:
- A project file was saved as
.dwt, or - The QNEW path is pointing to a standard
.dwgfile instead of a clean template.
Check the file extension and open the template directly to inspect its contents.
Q: I set QNEW correctly, but the [+] tab still ignores it.
A: The NEW command history may be overriding QNEW. Use the right-click method on the plus sign and manually select the correct template once to reset the session behavior.
If it persists across sessions, test under a new AutoCAD profile.
Q: My drawing tabs disappeared entirely.
A: Run:
FILETAB
If they do not return:
- Set
SDIto 0 - Check the View tab → ensure File Tabs are enabled
- Restart AutoCAD after changing SDI
Q: Can I reorder drawing tabs?
A: Yes. Click and drag them. The Start tab remains fixed on the far left unless disabled with STARTMODE = 0.
Q: Does the [+] sign behave differently from the Start tab’s “Start Drawing” button?
A: No. Both depend on QNEW and recent NEW command history. If one loads the wrong file, the other usually will too.
Q: Why does this issue affect some users but not others in the same company?
A: Template behavior is profile-specific. If profiles are not standardized or centrally deployed, each user’s session memory and QNEW path may differ.
Bottom Line
The plus sign is not broken. It is following internal logic tied to QNEW and command history.
Once you define the correct template path and reset the NEW command behavior, it becomes reliable again.
For individual users, this is a quick fix. For teams, it should be part of profile deployment and template control strategy.
