Separate

You can select a part of the mesh and separate it into a different object with the Separate tool.

To use the Separate tool:

1. Select the parts of the mesh you want to separate.

2. Press P and you’ll see a pop-up menu. You have to pick the Selected option to separate the selection. Use the By Material option to separate the mesh into parts that use different materials (only if you’ve applied different materials to parts of the mesh) or the Loose Parts option to separate the disconnected parts of the mesh (you don’t need to make a selection to use the Loose Parts option).
