# Car model to glTF with multiple parts

I have a model of a car which I have exported to a glTF. How can I group elements in Blender like the wheels so they appear separately in the JSON code? I have created Vertex Groups but they don’t seem to appear in the code.

If your car is all one mesh, go into Edit Mode on that mesh, select all the faces/vertices of the wheels, press P, and choose Selection. This will create a second object with the selected faces. Leave Edit Mode and rename the new object to a more descriptive name like "Wheels".
