About AutoCADMechanical1This chapter provides information about the AutoCAD Mechanical software application. Itdescribes the software package, the basic design features in the software, and the methods foraccessing commands.A brief overview of the Help, along with information about where to find resources for productlearning, training, and support are included.AutoCAD Mechanical Software PackageAutoCAD Mechanical is a 2D mechanical design and drafting solution forengineers, designers, and detailers. Its intelligent production drawing anddetailing features decrease the time required to create and change 2D productiondesigns. AutoCAD Mechanical introduces many 3D concepts in a familiar 2Denvironment. It is powered by AutoCAD , with its easy-to-use palette interfaceand time-saving xref functionality.The AutoCAD Mechanical design software package includes both AutoCADMechanical and AutoCAD. You can use one Options dialog box to customizesettings for both AutoCAD Mechanical and AutoCAD.Leveraging Legacy DataThe tools for migrating legacy data are installed automatically when you installthe AutoCAD Mechanical software. A separate utility tool is available for addingstructure to legacy files after they are migrated.3
The integrated Autodesk IGES Translator for transferring and sharing of CADdata between CAD/CAM/CAE systems is installed along with the AutoCADMechanical product.Newly generated files in AutoCAD Mechanical can be saved to a previousversion so that you can run multiple versions of AutoCAD Mechanical withinthe same environment.Starting AutoCAD MechanicalYou can start AutoCAD Mechanical by using one of the following procedures: Click Start on the task bar, and then choose Programs. Select Autodesk AutoCAD Mechanical 2010. On the desktop, double-click the AutoCAD Mechanical icon:AutoCAD Mechanical HelpThe Help in AutoCAD Mechanical provides information about AutoCADMechanical with the power pack.The Help is formatted for easy navigation, and includes: Content organized by the major functional areas of AutoCAD Mechanical,with Concept, Reference, and Procedure pages for each functional area.Procedure pages provide step by step instructions on how to execute agiven task. The linked Concept page provides background informationabout the procedure. The linked Reference pages contain informationabout all the commands and dialog boxes visited while performing theprocedure. Specific information about each of the features in the program. Concepts and procedures for the new features in this release. A keyword index and search function. Guides to system variables and accelerator keys. Acc
