Recessed Lights Video Tutorial
The updated recessed lights in Podium Browser have an auto-cut feature which allows you to simple insert the recessed lights in a ceiling or wall face. When that is done the face around the light fixture is trimmed automatically. This will not work on groups directly. You will need to open the group either using EditInPlace or SketchUp's EditGroup and then place the recessed light on the ceiling or wall face.
The above video tutorial demonstrates this time saving feature along with the accurately modeled recessed lights. All recessed lights are Podium render ready.
