I obtained a strange result tonight. I printed a 3D pdf of Climax 1551 and at the end of the process a "3D Parsing Error" was reported. A 2D pdf appeared in Adobe Reader without apparent errors. If one clicked on the drawing to "activate" a Picasso locomotive appeared. See below. Opening the file in Adobe Acrobat 9.0 also resulted in the Picasso locomotive. Until today I have not had problems with print to 3D pdf. Suggestions? I exited Alibre, reloaded the Climax and attempted to print again. No error message but same result. Up until these attempts I have not had any problems producing a 3D pdf . Thoughts?
