How to Change Dimension Style in AutoCAD Quickly

To change the dimension style in AutoCAD, open the Dimension Style Manager by typing D and pressing Enter. Select the style you want to modify or create a new one, then click Modify to adjust settings like text, lines, and symbols. Finally, set the desired style as current to apply it to your dimensions.

Syntax

The main command to manage dimension styles in AutoCAD is D. This opens the Dimension Style Manager window where you can:

New: Create a new dimension style.
Modify: Change settings of an existing style.
Set Current: Apply a style to new dimensions.
Override: Temporarily change style properties for selected dimensions.

Each style controls how dimensions look, including text size, arrowheads, lines, and units.

2. Select an existing style like <code>Standard</code> and click <code>Modify</code>.
3. Go to the <code>Text</code> tab and increase the text height to 0.25.
4. Go to the <code>Symbols and Arrows</code> tab and change the arrowhead type to <code>Closed Filled</code>.
5. Click <code>OK</code> to save changes.
6. Click <code>Set Current</code> to apply this style.
7. Click <code>Close</code> and create new dimensions to see the updated style.

Output

⚠️

Common Pitfalls

Common mistakes when changing dimension styles include:

Not setting the modified style as current, so new dimensions don't update.
Changing styles but forgetting to update existing dimensions, which keep old styles.
Overriding dimension properties directly instead of modifying the style, causing inconsistent appearance.
Using text heights or arrow sizes too large or small for the drawing scale.

Always check the scale and preview changes before applying.

autocad

/* Wrong way: Modifying dimension text directly without changing style */
SELECT dimension
PROPERTIES > Text height = 0.5

/* Right way: Modify dimension style text height */
D
Select style > Modify > Text tab > Text height = 0.5
Set Current > OK
