Steps to Add Dimension Values in AutoCAD

To modify or add dimension values in AutoCAD, begin by locating the dimension you wish to edit within your drawing area. Double-click on that dimension to bring up the editing options. Next, navigate to the Power Dimensioning tab and select Edit Geometry from the Format panel. This will open the Edit Geometry dialog box, where you can insert a desired numerical value into the Text offset from dimension line field. After entering your desired value, finalize the changes by returning to the Power Dimensioning tab and selecting Close Editor.

How to Create Dimensions in AutoCAD

Creating dimensions in AutoCAD involves a straightforward process. Start by clicking on the Annotate tab and selecting Dimensions from the Dimensions panel, choosing Linear as your dimension type. Once selected, specify the origin points for the first and second extension lines. If you wish to make the dimension line rotated, type ‘r’ at the prompt and enter the desired angle. Finally, click to place the dimension line in your drawing.

Modifying Dimension in AutoCAD

To adjust an existing dimension style, first access the Dimension Style Manager. Here, find and select the dimension style you wish to edit from the list. Click on the Modify button. Within the Modify Dimension Style dialog, navigate to the Fit tab. Under the Scale for Dimension Features section, choose the Use Overall Scale Of option to make your adjustments.
