Hey there! Are you looking to delete an item from a 3D OBJ file? Well, you're in luck because I've got some tips to make it super easy for you. First, open up your favorite 3D modeling software, whether it's Blender, Maya, or any other. Once you've loaded your OBJ file, navigate to the item you want to remove. Now, here's the fun part - simply select the item and press the delete key on your keyboard. It's as easy as that! If your software doesn't allow you to delete items directly, you can also use the 'Edit' or 'Delete' function in the menu. Once you've removed the item, don't forget to save your changes. And just like that, you've successfully deleted an item from your 3D OBJ file. Happy designing!
