How Do You Scale a Drawing Without Changing Dimensions in AutoCAD?

by

In AutoCAD, scaling a drawing is a common task that allows you to increase or decrease its size while maintaining its proportions. However, sometimes you may need to scale a drawing without changing its dimensions. This can be useful in situations where you want to keep the same physical size of the drawing, but need it to appear larger or smaller on the screen or on paper.

Understanding Scaling in AutoCAD

Scaling in AutoCAD refers to resizing an object or a set of objects uniformly. It involves multiplying the coordinates of the objects by a scale factor. By default, when you scale an object in AutoCAD, it changes both its size and dimensions.

However, there are times when you want to preserve the dimensions of an object while changing only its size. This technique is commonly used when working with architectural drawings or technical diagrams.

Steps to Scale a Drawing Without Changing Dimensions

To scale a drawing without changing its dimensions in AutoCAD, follow these steps:

  1. Select the objects that you want to scale.
  2. Type ‘SCALE’ in the command line and press Enter.
  3. Specify the base point for scaling. This is the reference point around which your selected objects will be scaled.
  4. Type ‘R’ and press Enter.

    The ‘Reference’ option allows you to specify a reference length or distance that will remain unchanged during scaling.

  5. Select two points on your drawing that represent the desired reference length or distance. For example, if you want to scale your drawing by 50% without changing any dimensions, select two points that are 1 meter apart.
  6. Specify the new length or distance. In this case, you would enter ‘0.5’ since you want to scale the drawing by 50%.

Scaling Tips

Here are a few additional tips to keep in mind when scaling a drawing without changing its dimensions in AutoCAD:

  • Use the Scale Tool: Another way to access the scale command is through the Scale tool on the Modify panel of the Home tab.
  • Use Reference Lengths: Always try to use reference lengths when scaling drawings. This ensures that the proportions of your objects remain accurate.
  • Annotate Your Drawings: After scaling, make sure to update any annotations or dimensions accordingly. This will ensure that your drawing remains consistent and accurate.

Scaling a drawing without changing its dimensions can be a useful technique in AutoCAD. By following these steps and keeping these tips in mind, you can easily scale your drawings while maintaining their original proportions and dimensions.

Remember, practice makes perfect! So, don’t hesitate to experiment with different scaling techniques and settings to achieve the desired results in your AutoCAD projects.
