Understanding Dimension Values in AutoCAD
When working in AutoCAD, adjusting dimension values is crucial for accurate representation in technical drawings. Modifying these values can involve changing text, styles, or even numeric values associated with dimensions. This guide will outline the steps needed to effectively modify dimension values in AutoCAD.
Changing Dimension Text
1. **Select the Dimension**: Begin by clicking on the dimension line or text that requires modification.
2. **Access the Edit Options**: Right-click on the selected dimension and choose the “Edit” option from the context menu.
3. **Edit Text**: In the Edit Dimension dialog, locate the text box. Here, you can directly input your desired text or value.

2. **Create a New Dimension Style**: Click “New” to start a dimension style designed for a different unit system (e.g., switching from inches to millimeters).
3. **Setup New Style Properties**: In the New Dimension Style dialog box, name your new style. Use existing styles as a template if needed.
4. **Modify Units**: Under the ‘Primary Units’ tab, set the Suffix to ‘mm’ and input ‘25.4’ as the Scale Factor to convert inches to millimeters.
5. **Finalize New Style**: Click “OK” and apply the style to the dimensions that require adjustment.
