Can’t change annotative scale in AutoCAD?

Brief Answer: If you can’t change the annotative scale in AutoCAD, it could be due to locked viewports, the object not being annotative, or global scale settings.

Detailed Explanation and Solutions:

1. Locked Viewports:
   • Issue: In paper space, a locked viewport prevents scale changes.
   • Solution:
     • Double-click inside the viewport to activate it.
     • Unlock the viewport by clicking on its border, then in the Properties palette, change ‘Display Locked’ to ‘No’.
     • Change the annotative scale from the viewport properties.
2. Object Not Annotative:
   • Problem: The object may not be set as annotative.
   • Solution:
     • Select the object.
     • In the Properties palette, under ‘Annotative’, change to ‘Yes’.
     • Apply the desired annotative scale.
3. Global Scale Factor:
   • Global Scale Issue: The drawing’s global scale setting affects annotative objects.
   • Adjust Global Scale:
     • Type ANNOALLVISIBLE and set it to 1.
     • Use DIMSCALE or LTSCALE to adjust the global scale factor.
4. Annotative Style Settings:
   • Style Limitation: The annotative style may have limitations.
   • Modify Style:
     • Use DIMSTYLE, TEXTSTYLE, or similar commands to edit the specific annotative style.
     • Adjust the scale settings within the style.

Key Points:

• Unlock Viewports: Ensure viewports in paper space are not locked.
• Set Objects to Annotative: Change object properties to ‘Annotative’.
• Manage Global Scales: Adjust global scale factors if necessary.

Trouble changing the annotative scale in AutoCAD typically involves viewport lock status, object properties, and global drawing settings. Addressing these areas should allow for scale adjustments.
