FAQ

1. What is the difference between the Erase and Trim commands in AutoCAD?
The Erase command removes selected objects entirely from the drawing, while the Trim command modifies the edges of objects, allowing you to cut or shorten them without permanently removing them.

2. How can I delete an object that is locked or embedded in a block?
To delete a locked or embedded object, you must first unlock it or edit the block. Use the ‘Unlock’ command, or create a temporary block reference that allows you to access and remove the desired object.

3. Will deleting features permanently remove them from my drawing?
Yes, unless you’ve implemented a backup or version control system, deletion in AutoCAD is a permanent action. Always ensure you have saved previous versions or copies before making irreversible changes.
