How Do You Scale Without Changing Dimensions in AutoCAD?

by

In AutoCAD, scaling is a common task that allows you to adjust the size of objects without changing their dimensions. This can be particularly useful when working on complex drawings or when you need to fit multiple objects within a specified space. In this tutorial, I will show you how to scale objects in AutoCAD without altering their dimensions.

Using the Scale Command

The Scale command in AutoCAD allows you to resize objects by specifying a base point and a scale factor. To use this command:

  1. Select the objects you want to scale by clicking on them.
  2. Type “SCALE” in the command line and press Enter.
  3. Specify the base point by clicking on a point in your drawing or by entering coordinates.
  4. Enter the scale factor, which determines how much larger or smaller the objects will become. For example, entering 2 will double their size, while entering 0.5 will halve it.
  5. Press Enter to complete the scaling operation.

Note: When scaling objects using the Scale command, it is important to select the correct base point. The base point acts as an anchor around which the objects will be resized. Choosing a different base point can yield different results.

The Reference Option

In addition to specifying a scale factor, AutoCAD’s Scale command also offers a reference option that allows you to scale objects based on a reference length or distance. This can be particularly useful when you need to maintain specific proportions within your drawing.

  1. Select the objects you want to scale by clicking on them.
  2. Type “SCALE” in the command line and press Enter.
  3. Specify the base point by clicking on a point in your drawing or by entering coordinates.
  4. Type “R” and press Enter to activate the reference option.
  5. Enter the original reference length or distance.
  6. Enter the new desired length or distance. AutoCAD will automatically calculate the scale factor based on these values.

Note: The reference option can be particularly useful when working with architectural drawings or when you need to maintain accurate scaling based on real-world measurements.

The Scale Factor

The scale factor determines how much larger or smaller the objects will become when scaled. It is important to understand that this value is relative to the original size of the objects. For example, a scale factor of 1 will result in no change, while a scale factor of 2 will double their size.

Tips:

  • To make objects smaller, use a scale factor less than 1 (e.g., 0.5 for half size).
  • To make objects larger, use a scale factor greater than 1 (e., 2 for double size).

Conclusion

In conclusion, AutoCAD offers powerful scaling capabilities that allow you to resize objects without altering their dimensions. By using the Scale command and understanding how to specify a base point, set a scale factor, and utilize the reference option, you can easily adjust object sizes within your drawings while maintaining accuracy and proportionality.

Experiment with different scaling techniques and practice using different base points to achieve the desired results. Happy scaling!
