Measuring Objects in AutoCAD

1. Initiate the Measurement Tool: Click on the “MEASURE” command from the menu.

2. Choose the Area Option: In the measurement tool menu, select the "Area" option to measure the area enclosed by your specified points.

3. Select Points: Click to specify the points of the perimeter for measurement. Utilize object snaps for enhanced precision.

4. Complete the Measurement: After selecting all necessary points, press Enter to finalize the measurement reading.

Troubleshooting Dimension Visibility Issues

• Layer Control Check: Ensure that all relevant layers are turned on. If you can see the dimension line but the text is missing, this likely indicates that the text style is set too small for the current drawing scale.

• Review Paper Space: If problems persist, consider switching to paperspace (layout view) to manage your dimensions more effectively.

Adjusting Dimension Sizes

1. Edit Dimension Text: Right-click on the dimension you want to change and select "Edit."

2. Modify the Text: A dialog box will open where you can adjust the text in the provided text box.

3. Text Positioning: If necessary, alter the line justification or reposition the dimension line to better fit the layout of your drawing.

Understanding Dimension Commands

• Access Basic Commands: AutoCAD offers various shortcuts for dimensioning. For instance, the "DIM" command allows quick access to dimension options. Simply type “DIM” into the command line and follow the on-screen prompts.

• Utilize Object Selection: When dimensioning, click on the objects or points you wish to measure. The DIM command will automatically suggest suitable dimension types based on your selection.
