How to Scale Object in AutoCAD Without Changing Dimension?

Understanding Scaling in AutoCAD

Scaling in AutoCAD is essential to adjust the size of objects without altering their dimensions. This process ensures that the drawings remain proportional and accurate when zoomed in or out.

Step-by-Step Guide to Scaling Objects Without Changing Dimensions

Step 1: Open Your Drawing

Launch AutoCAD 2025 and open the drawing that contains the object you wish to scale. Navigate to the file menu or use the open command to access your drawing.

Step 2: Select the Object

Use your mouse to click on the object you want to scale. If you need to select multiple objects, click and drag to window-select or hold down the Shift key while clicking on each object individually.

Step 3: Initiate the Scale Command

Type SCALE into the command line and press Enter. The command will activate a new prompt asking for your base point.

Step 4: Specify the Base Point

The base point is a reference point around which the scaling will occur. Click on a point within your drawing, or you can type in specific coordinates to determine the location.

Step 5: Enter the Scale Factor

At this point, you need to specify your scaling factor. If you want the object to retain its dimensions while it is displayed at a different size, you must use a scale factor of 1. Enter 1 and hit Enter.

Step 6: Verify Your Adjustments

After applying the scale, it’s good practice to zoom in and out using the Z + Enter A + Enter command to ensure your object appears correctly in the layout without any dimensional changes.

Tips for Effective Scaling

  • Regularly verify that your working units correspond to your intended scale. Check the unit settings in the drawing properties to avoid confusion.
  • Consider using the Properties panel to review object properties after scaling. This can confirm that dimensions remain intact.

FAQ

1. Can I undo a scaling action in AutoCAD?

Yes, you can undo a scaling action by pressing Ctrl + Z on your keyboard immediately after the action or use the command UNDO in the command line.

2. How do I check the dimensions of an object after scaling?

Select the object and use the DIM command to create a dimension. This will allow you to see the current dimensions to confirm they remain unchanged.

3. Is it possible to scale while in paper space instead of model space?

Yes, you can scale objects in paper space, but keep in mind that the dimensions must be adjusted to fit the required print scale. Use the viewport settings to control how the model is displayed in paper space.
