add new coordinate system in solid works

• Define the new coordinate system by a point (in new sketch)
• Select move/copy in the insert

• select the body to move
• select the new point (in step 1)

• in the lower box: select the origin point

• now the new origin defined at the new define point (step1)
• at this step we will add the coordinate system

Software Requirements

Registration requires that the following two products be installed on your computer:

• SolidWorks
• SimMechanics Link — See Install and Register SimMechanics Link Software

  Download SimMechanics Link Software

  You can download SimMechanics Link software directly from the MathWorks^® website:

  1. Visit the SimMechanics Link download website athttp://www.mathworks.com/products/simmechanics/download_smlink.html.
  2. Select the software version to install.
  3. Click Submit.
  4. Save the installation files in a convenient folder.
     Do not extract the zip file.
  
  

  Install SimMechanics Link Software

  Install SimMechanics Link software from the MATLAB command line:

  1. Start MATLAB.

     Note:   You may need administrator privileges to complete the installation.

  2. At the MATLAB command line enter:

     path(path, '<installation_file_folder>')

     replacing <installation_file_folder> with the path to the folder with the installation files.
  3. At the MATLAB command line, enter:

     install_addon('<zip_file_name>.zip')

     replacing <zip_file_name> with the name of the zip file that you downloaded (e.g., smlink.r2014b.win64). The command extracts the zip archive files to the MATLAB root directory

  Register SimMechanics Link

  To register SimMechanics Link with the CAD platform:

  1. Start a new MATLAB^® session.
  2. At the MATLAB command line, enter smlink_linksw.
  3. MATLAB displays a message stating that linking was successful. You can close MATLAB.

  
  

  Add SimMechanics Link to SolidWorks Menu bar

  SimMechanics Link is now registered as a SolidWorks add-in tool. To use the tool, select the tool as an active add-in:

  1. Open SolidWorks.
  2. In the menu bar, select Tools > Add-Ins.
  3. In the Add-Ins dialog box, select SimMechanics Link.

  The menu bar of the CAD platform displays a SimMechanics Link menu item.
