Please can I ask that you alter your procedure slightly when creating our floor plans. I see that you put a flooring in that you have set up in SmartDraw, this is resulting in the floor texture not working properly so please can you create the shape of the room and insert the floor as a picture each time.
I have created a quick video example of how I want you to do the flooring so please can you start doing this, and let me know if you have any problems?
