Translations:Creating a simple part with Draft and Part WB/20/en

From FreeCAD Documentation

To make the chamfer we need to have a line with the correct inclination and also be able to position it correctly. Let us begin with the position, which is on coordinate (50, 50, 0). In the current profile we do not have a point there, so let’s create one by making a temporary help line. First select the left vertical Line, then create the help line by Duplicate selection in Edit → Duplicate selection, Line001 is created. Use the Property editor and move Line001 50 mm in x-direction using the Placement property. Next duplicate the lower horizontal edge, and change the angle of the edge to 30 degrees, once again using the Placement property. The model should now look like the image below.
