How can I download the HTML tutorial of AutoCAD Map 3D 2011 for studying?
The 2011, 2012, 2013, 2014, and 2015 versions of AutoCAD MAP 3D are somehow the same. However there is a page where you can see all the documentation and tutorial available for this application.
Documentation page: http://knowledge.autodesk.com/support/autocad-map-3d/getting-started/caas/CloudHelp/cloudhelp/ENU/123112/files/map3d-documentation-html.html
To save a tutorial, open it with your browser and then go to File > Save Page as . Choose a location and the browser will save an HTML file with a folder of the same name where all the resources are found.
