How Do You Scale a Line in AutoCAD?

by

Scaling a line in AutoCAD is a fundamental skill that every CAD drafter should master. Whether you need to enlarge or reduce the size of an object, scaling allows you to make precise adjustments while maintaining proportionality.

In this tutorial, we will explore different methods to scale lines in AutoCAD.

Method 1: Using the Scale Command

The Scale command is one of the easiest and most straightforward methods to scale a line in AutoCAD. Follow these steps:

  1. Select the line you want to scale by clicking on it.
  2. Type “SCALE” into the command line or access it from the Modify panel.
  3. Specify a base point by clicking anywhere on the screen. This point will act as the reference for scaling.
  4. Enter the desired scale factor.

    For example, if you want to double the size of the line, enter “2“. To reduce its size by half, enter “0.5“.

  5. Press Enter and your line will be scaled accordingly.

Tips:

  • To maintain proportionality: Instead of entering a single scale factor, you can specify separate X and Y factors by typing “SX,Y” after selecting your base point. For example, “S1.5,0.5” will stretch the line horizontally by 1.5 times and compress it vertically by 0.5 times.
  • To scale multiple lines: You can select multiple lines before using the Scale command to scale them all at once.

Method 2: Grips Editing

Another efficient way to scale lines in AutoCAD is by using grips. Grips are small squares or circles that appear when you select an object, allowing you to manipulate its properties. Here’s how you can use grips to scale a line:

  1. Select the line you want to scale.
  2. Click on one of the grips at either end of the line.
  3. Hover your cursor over the grip until it turns into a double-headed arrow.
  4. Click and drag the grip to adjust the length of the line as desired.

Using grips for scaling is particularly handy when you need to make quick adjustments without entering specific measurements. However, keep in mind that this method doesn’t offer precise control over scaling factors.

Method 3: Stretch Command

The Stretch command can also be used effectively for scaling lines in AutoCAD. While primarily used for stretching objects, it can also be utilized for scaling purposes. Follow these steps:

  1. Type “STRETCH” into the command line or access it from the Modify panel.
  2. Select the line you want to scale.
  3. Specify a crossing window or select individual segments of the line to include in your selection set.
  4. Click and drag one of the selected grips towards or away from the line’s endpoint to adjust its length proportionally.

Tips:

  • To stretch only one side: After selecting your grip, press and hold down the Shift key while dragging it towards or away from the line’s endpoint. This restricts stretching to one side only.

Scaling lines in AutoCAD is an essential skill that helps maintain precision and accuracy in your drawings. By mastering these methods, you’ll be able to scale lines effortlessly, allowing you to create detailed and professional designs.
