I found this by accident
http://exchange.autodesk.com/autocad/sites/default/files/autocadLT_pdf_cust-guide_enu_v2.pdf
I am very pleased but now keen to know what other documentation Autodesk are openly hosting, if i browse back thorugh path I do nto get to any kind of directory listing of selection of documents/software.
It just takes me back to http://exchange.autodesk.com before I can navigate forward again, and then I cannot find this document if i start from that point. Interested in everything LT (2012/2013) Full AutoCAD and also Revit.
As I was posting, I found this
http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=12272439&linkID=10809853
This takes me to that original link and brings up other pdf documents avaible. As yet, no 2013, but some nice bits all the same.
If anyone knows of Authrosied Autodesk hosted documents, I woudl be extreamly greatful.
Cheers.....Q
