You can remove the texture for a selected surface using the Wireframe button. When Wireframe is enabled, textures are replaced with a wireframe view of the surface. When used, a 3D model will be changed to show its polygon frame.

To convert to wireframe:

1. In the scene, select the surface to convert to wireframe.
2. In the Geometry menu, enable Wireframe.

   
   

   The selected surface becomes a wireframe surface.
