Hi All, I've got a weird one. A drawing with a surface in 2015 looks fine until I save and close. When I re-open the file, the surface won't display. The data is still there, as you can see in the attached drawing by looking at the surface statistics, and the fact that the labels are still functioning. I've attached the problem - the surface you see is imported from a LandXML. It's not an issue with the style - as far as I can see this happens with any/all styles I apply to it. Layers are all on. My graphics drivers are all current (based on the recommended driver from Autodesk for the Quadro fx 1800) A
