  AutoCAD Mechanical software extends the capabilities of
  AutoCAD so that you can quickly create and manage mechanical
  drawings.
  Autodesk Mechanical Desktop 2009 (MDT) software includes all
  the functionality of AutoCAD, plus libraries of standards-based
  parts and tools to help accelerate mechanical CAD.
  The objective of using Mechanical Desktop design software
  package is to insert 2D or 3D mechanical parts (screws, washers,
  nuts, shafts, keys, bearings, springs, …etc.). This software is used
  in mechanical design analysis and calculations were made after
  applying forces on the mechanical parts and inserting the data
  needed to perform the calculations.

  How to draw a 2D or 3D Screw by using Mechanical Desktop?
  1- Menu content2D or 3D Fasteners Screws
  2- In the command line write AMSCREW2D or AMSCREW3D
  After a Screw dialog box appear, select a type of screw and view to insert.
  Depending on the selected view there are differences in the insertion process.
