Thank you for your replies to this. I noticed that the 2014 version already comes with a flatten option in the right click, 'flatten faces' this is all I really need. Thought it would be nice to take a 3D component from warehouse such as a plant, flatten it on the red or green axis so I can use it in 'Top' camera view, so I can use it like a plant symbol in site plan. I have noticed Sketchup and layout has limited 2D flat plant symbols I can use for Landscape Design.
Thanks,
