AutoCAD LEN Shortcut : LENGTHEN : Changes The Length Of Objects And The Included Angle Of Arcs

If you’re delving into AutoCAD, understanding the lengthen-shortcut is essential for efficiently adjusting object lengths and arc angles. This guide will cover what the shortcut is, how to use it step-by-step, reasons for potential issues, and alternative commands you can employ.

What is the Lengthen-Shortcut?

The AutoCAD LEN Shortcut referred to as LENGTHEN, allows you to modify the length of objects as well as the included angle of arcs. This makes it a crucial tool in creating precise drawings where adjustments are often necessary.

How to Use the Lengthen-Shortcut (Step by Step)

To effectively utilize the lengthen-shortcut in your drawings, follow these steps:

  1. Activate the Lengthen Command

    • Type LENGTHEN in the command line or use the shortcut key LEN.

  2. Select the Object

    • Choose the object or arc you wish to lengthen or shorten.

  3. Choose Your Method

    • You will be prompted to select among options such as:
      • Total Length: Enter a new length for the object.
      • Percentage: Increase or decrease the object’s length by a specified percentage.
      • Delta: Extend or shorten the object by a specified distance.

  4. Input Your Values

    • Depending on the method you selected, provide the required numeric input and press Enter.

  5. Review Your Changes

    • Check if the modifications meet your design requirements. You can undo changes if necessary.

Why Lengthen-Shortcut Might Not Work

There are several reasons why the lengthen-shortcut may not yield the expected results:

  1. Object Type: Not all objects can be adjusted with the LENGTHEN command. Lines and arcs work well, but other complex shapes may not.

  2. Selection Issues: Ensure you have correctly selected the object, as a misclick might lead to a wrong selection.

  3. Command Constraints: If the command encounters constraints (like locked layers), it will fail to apply.

  4. Invalid Inputs: Entering non-numeric values or invalid lengths can lead to errors.

Alternative Methods

If the lengthen-shortcut doesn’t work as intended, consider these alternatives:

  • Stretch Command: Use STRETCH for altering segments of lines within a group.
  • Scale Command: Apply the SCALE command if you need to proportionally adjust the size of an object.
  • Move Command: If adjustments are minor, simply using the MOVE command in conjunction with grips might suffice.

Tips for Effective Use

  • Practice Makes Perfect: Experiment with the LENGTHEN command in a test drawing to see how different inputs affect your objects.
  • Check Snap Settings: Ensure your snap settings are set properly to avoid misalignment.
  • Use Undo: Familiarize yourself with the CTRL + Z command to quickly revert unintended changes.
