Common Pitfalls

Common mistakes when creating dimension styles include:

• Not setting the new style as current, so dimensions still use the old style.
• Forgetting to adjust text height or arrow size, resulting in unreadable dimensions.
• Overcomplicating settings, which can cause inconsistent dimension appearance.
• Not saving changes before closing the manager.

Always preview your dimension style on sample dimensions to ensure it looks right.
