How To Change Dim Scale In AutoCAD?

To effectively adjust dimension scales in AutoCAD, follow these detailed steps.

Understanding Dimension Styles

Dimension styles play a crucial role in how dimensions appear in AutoCAD. Changing the scale of dimensions affects their presentation in drawings. Before making adjustments, it’s beneficial to familiarize yourself with the Dimension Style Manager, which allows you to view and modify existing dimension styles or create new ones.

Step-by-Step Guide to Change Dimension Scale

1. Access the Dimension Style Manager
   Open AutoCAD and navigate to the Home tab. Look for the Annotation panel and find the option labeled Dimension Style. Click on it to launch the Dimension Style Manager.

2. Select the Desired Dimension Style
   Once the Dimension Style Manager is open, a list of existing dimension styles will be displayed. Identify and select the specific style you wish to modify.

3. Modify the Selected Style
   After selecting your dimension style, click the Modify button. This action will open the Modify Dimension Style dialog box where you can adjust various settings.

4. Adjust Scale Settings
   In the Modify Dimension Style dialog, locate and click on the Fit tab. Here, you can change the scale settings for dimension features. Look for an option labeled Scale for Dimension Features. This value can be adjusted based on your requirements to ensure dimensions are accurately scaled.

5. Apply and Save Changes
   After setting the desired scale, click OK to apply the changes and then close the Dimension Style Manager by clicking Close.

Changing Text Height of Dimensions

Sometimes, along with scale adjustments, you may want to change the text height. To do this:

1. Open the Dimension Style Manager and select your desired style.
2. Click on Modify, then navigate to the Text tab.
3. Here, under Text Appearance, either choose an existing text style or input a fixed height for your dimension text in the corresponding box.
4. Save changes and exit as before.

Additional Tips for Scaling in AutoCAD

• Using Command Line: You can also use command line input to quickly change dimensions. Enter the command for scaling (e.g., SC for Scale) and follow the prompts to specify your scale factor.
• Preview Changes: Take advantage of dimension previews while adjusting settings. This feature helps visualize how your changes will manifest in the drawing.
