Hi!
Our customers will use a 3D PDF Tool to show the Surface and the draped image in a 3D PDF file!
But with the quality from the draped image we cant do it good enough! Just in the newst Versions
I know that Autodesk changed something because in Version 2011 (Civil 3D) the draped image had a good quality!
There should be an option to get a better draped image (Quality) in the Model view!
Here some Screenshots (Civil 2011 and Civil 2015)
