How Do You Change Trim Mode in AutoCAD?

by

In AutoCAD, the Trim command is a powerful tool that allows you to remove unwanted portions of lines, arcs, or other objects. However, before you can start trimming away, it’s important to understand how to change the trim mode in AutoCAD.

Step 1: Accessing the Trim Command

To access the Trim command in AutoCAD, you have several options. You can either:

  • Click on the “Trim” button located in the Modify panel of the Home tab.
  • Type “TR” on the command line and press Enter.
  • Use the keyboard shortcut “TR” (if available).

Once you have accessed the Trim command, you can proceed to change its trim mode.

Step 2: Changing Trim Mode

The default trim mode in AutoCAD is “Fence.” However, there are three different trim modes available:

1. Fence

The Fence trim mode allows you to select a series of objects using a fence line. Any portion of an object that crosses or touches the fence line will be trimmed.

2. Crossing

The Crossing trim mode allows you to select objects by crossing a selection window or polygon. Objects that are completely or partially inside the selection window will be trimmed.

3. Projection

The Projection trim mode is useful when working with 3D objects. It allows you to select objects by projecting a cutting edge onto them. Objects that intersect with the projected cutting edge will be trimmed.

To change the trim mode in AutoCAD, follow these steps:

  1. Type “TRIMMODE” on the command line and press Enter.
  2. Enter the desired trim mode (Fence, Crossing, or Projection) and press Enter.

You have now successfully changed the trim mode in AutoCAD!

Additional Tips

Here are some additional tips to enhance your trimming experience in AutoCAD:

  • Use object selection filters: AutoCAD provides various object selection filters that allow you to narrow down your selection, making the trimming process more precise. You can access these filters from the status bar or by typing “SELECT” on the command line.
  • Combine trim modes: In some cases, you may need to use multiple trim modes within a single command.

    For example, you might start with a Fence trim and then switch to a Crossing trim. To do this, simply follow the same steps mentioned above and select the desired trim mode when prompted.

By mastering the art of changing trim modes in AutoCAD, you’ll gain greater control over your designs and improve your productivity. Experiment with different trim modes to find the one that best suits your needs!
