I’m on the look out for a Cor C++ library / SDK that will allow me to either write a 3d PDF directly, or convert a DXF or DWG into a 3D PDF. So far I have come up with the PDF3d library which fits the bill, but is reasonably costly and has an expensive per user run time license. I don’t mind a reasonable SDK cost, but the per seat cost kills it for me.
Anyone aware of any alternatives?
I use PDF XChange a lot for 2D CAD plots to PDF and it works well. I don’t know if (I don’t think so) it does 3D. I could find no mention of it at first glance on their site.
Your other option is a 3D DWF. Also consider that DWG TrueView is a free viewer and printer that handles 3D DWGs natively. You used to be able to automate TrueView through COM but I’m not sure if that is still so. Here is a blog post on some automation of Trueview – http://through-the-interface.typepad.com/through_the_interface/2007/10/au-handouts-t-1.html
