2.1 Prerequisites

The following steps assume that the Windows user has admin rights and can do the following on the PC:

  • Download and install OpenSCAD (may require administrative rights).
  • If using the optional batch files, modify the path environment variable.

Preparations:

  1. Download and install OpenSCAD from http://www.openscad.org/.

    2. On Windows OS, the installer may need to be executed with administrator rights by right mouse clicking on the .exe and selecting "Run as Administrator."

    The default installation directory is C:\Program Files\OpenSCAD.

  2. Create a project directory C:\OpenSCAD\Projects and download the sensor script zip file into this directory. Unzip the contents.
  3. If using the optional batch files, modify the path environment variable by appending the path C:\Program Files\OpenSCAD (see the following steps). Modifying the path environment variable is required to run the batch files without providing a path to OpenSCAD.exe on the command line.

To modify the environment path in Windows 10 (optional):

  1. Open System Properties (right click Computer in the start menu, or use the keyboard shortcut Winkey+Pause)
  2. Click Advanced system settings in the sidebar.
  3. Click Environmental Variables.
  4. From the system variables, select "PATH" and click Edit.
  5. Add the OpenSCAD installation directory path C:\Program Files\OpenSCAD to the end of the path list.
