Starting the oar is pretty easy. In Chapter 4, Modeling with Vertices, Edges, and Faces, you looked at the basic shapes that are present in Blender; this is where you will begin:
Open Blender.
Press X to delete the default cube.
Press Shift + A and select a cylinder from the pop-up menu.
In the Add Cylinder section of Tool Shelf set Vertices to
12, Radius to0.083, and Depth to4.2. You can use the Tab key to jump between the Vertices, Radius, and Depth buttons. Set the Cap Fill Type to Ngon. This will make the oar handle and shaft as seen in the following screenshot. Press Enter after setting the values.
Press the Tab key to get into Edit Mode.
Press the NumPad 1 key to set the view to Front and then press the NumPad 5 key to set the view to Ortho.
Zoom into the cylinder.
Make sure that the Limit selection to visible button is light gray in the 3D View header, as shown by the highlighted button on the right...
