How Do I Delete Part of an Object in AutoCAD?

by

In AutoCAD, there are various tools and commands that allow you to manipulate objects and make precise edits. One common task you may encounter is the need to delete part of an object. This can be done using a combination of selection and modification tools.

Selecting the Object

The first step is to select the object that you want to edit. You can do this by using the selection tools available in AutoCAD. These tools include:

  • Window Selection: This allows you to select objects by creating a window or crossing selection. To use this tool, simply click and drag your cursor to create a rectangular window or crossing over the desired objects.
  • Previous Selection: This allows you to select objects that were previously selected.

    To use this tool, simply type “P” on your keyboard and press Enter.

  • Select All: This allows you to select all objects in the drawing. To use this tool, simply type “A” on your keyboard and press Enter.

Trimming the Object

Once you have selected the object, you can proceed with trimming it. Trimming allows you to remove unwanted portions of an object by defining a cutting edge.

To trim part of an object, follow these steps:

  1. Select the Trim command: Type “TRIM” on your keyboard and press Enter, or click on the Trim icon in the Modify panel of the Home tab.
  2. Select cutting edges: Click on the parts of other objects that will serve as cutting edges. These cutting edges will define what portion of your selected object will be trimmed.
  3. Select the object to trim: Click on the part of the selected object that you want to delete. AutoCAD will remove the portion of the object that is outside of the defined cutting edges.

It’s important to note that when trimming an object, you can select multiple cutting edges and trim multiple objects at once. This can save you time and effort when editing complex drawings.

Additional Tips

Here are some additional tips to help you efficiently delete part of an object in AutoCAD:

  • Use Object Snaps: Object snaps can help you accurately select cutting edges and objects to trim. Enable object snaps by clicking on the Object Snap icon in the status bar or by pressing F3 on your keyboard.
  • Use Layers: If your drawing contains multiple layers, make sure that the layer containing the objects you want to trim is visible and unlocked.

    You can control layer visibility and locks using the Layer Properties Manager.

  • Undo/Redo: If you make a mistake while trimming an object, you can use the Undo command (Ctrl+Z) to revert back to a previous state. Similarly, you can use the Redo command (Ctrl+Y) to redo a previously undone action.

In conclusion, deleting part of an object in AutoCAD is a straightforward process that involves selecting and trimming. By using these tools effectively, you can make precise edits and modifications to your drawings with ease.
