AutoCAD 2010 was made available on Tuesday. I'll resist the temptation to make some type of pun based on 2010: Odyssey Two by Arthur C. Clarke. Instead I'll harken back to August 24, 2004 with Shaan Hurley's original Between the Lines posting that included the impossible triangle:
The drawing was created by Patrick EMIN of the French CAD web site http://www.cadxp.com. I have always liked this drawing, so I thought I would try it out with AutoCAD 2010. I created a 3D DWF of the drawing. The default for AutoCAD 2010 is now DWFx. So my Publish command created Le triangle impossible 2010.dwfx. I loaded this file into Microsoft Internet Explorer 7 and got the message:
This is indeed a 3D file. Internet Explorer 7 only views the 2D data in a DWFx file. The message displayed lets me know that there is more in the file to be viewed.
While it is true that I could have installed Autodesk Design Review 2010 to view the 3D data, as a Labs guy, I uploaded Patrick's design to Project Freewheel. This lets anyone view 2D or 3D design data in a DWFx without installing anything - just using their browser. You can even embed the design in a web page as I have done in this blog entry.
But the fun does not stop there. As AutoCAD 2010 exports to STL files, I also wanted to hold the impossible triangle in my very hands. AutoCAD Product Manager, Guillermo Melantoni, helped me clean up the data so it would be water tight. I then exported the drawing as an STL file and had the design printed on a 3D printer using the Red Eye On Demand service. Here it is:
Sharing designs electronically (DWFx) and physically (STL) is alive in the lab.
