Introduction
FreeCAD is a free, open-source CAD package that was under development for years; and recently it has produced a "release" version. By attracting developers from all over the design community, FreeCAD has assembled an impressive collection of features and add-ons.
Download FreeCAD
To get started, please visit the FreeCAD download site if you haven't already done so. When you click on the link it takes you to the FreeCAD download page.
You may also want to download the PDF user manual and look at it. It gives detailed instructions on how to install the package. You may also want to look at the navigation options on pp. 31-32 if you are used to a particular set of mouse actions to zoom, pan and rotate the view.
Most of the FreeCAD user support is done through a Wiki. If you go to the installation instructions you will find more information on downloading and installing FreeCAD.
Load FreeCAD and Open a Sketch
Double-click on the 
FreeCAD icon (or shortcut) on the desktop. The window will show a startup dialog as shown below. Click on New File - Parametric Part to create a new part.
FreeCAD is available on a variety of computer brands and operating systems, including Windows, MacOS, and Linux. For this tutorial, we focus on the PC interface which uses a three-button mouse.
On the PC, the LEFT mouse button is used for selection.
The MIDDLE button (actually a wheel) is used to move the part rendering around in the graphical space. The wheel functions as BOTH a button and a track-wheel, so there is a lot you can do with it.
If you spin the wheel, that causes the image to zoom in and out.
If you click down on the wheel and drag the mouse, this causes the image to pan around the window.
Rotating the image is done through the (
) orientation icon in the upper-right corner of the window. The faces of the solid are controls that deliver the orientation indicated. The arrow buttons in the margins cause the image to rotate by an increment.
