Using landmark 2011. There is no 3d pizza oven in Landmark, but I have found some in Sketchup warehouse. How do I import a 3d object from sketchup warehouse into landmark? Can someone please tell me step by step how to do this, as I have never used sketchup or imported anything else into Landmark, have only used whats avaailable in the Landmark libraries. Thankyou.
