1st Method - By Constructive Solid Geometry

 * Start with the Part Workbench (View > Workbench > Part menu)
 * If you haven't opened a new FreeCAD document (most of the FreeCAD window looks greyed-out), from the pull-down menu click File > New or click the Create A New Document tool [[Image:Document-new.svg|32px]].
 * Click on the [[Image:Part_Box.png|32px]] Box button to create a box
 * Change its dimensions by selecting it either in the 3D space, or by clicking it in the Project tab to the left, then
 * Click on the Data tab at the bottom, and change values for Height, Length and Width to 750mm, 50 and 50 (see Fig. 1.1)
 * Create a second box the same way, but with values 750, 40 and 40mm. By default this box will be superimposed on the first one. (see Fig. 1.2)
 * You'll now subtract the second box from the first. Select the first shape first (named Box), then the second one (named Box001), the selection order is important! (Make sure that both shapes are selected in the Project tree. One thing to remember: in Inventor navigation mode, Ctrl + click does not work for multiple selection. Switch to either CAD or Blender selection.)
 * On the Part Workbench toolbar, click on the [[Image:Part_Cut.png|32px]] Cut tool.
