Boolean with an Extrude

Construction of an odd shape

Before I begin I wonder what basic shape to start with. If I see a shape with a circle I will almost certainly use a cylinder or sphere as the start shape. So I had placed it correctly according to the image plane and then I noticed I wanted a flat side to be pulled up with vertices pulled closer together. So I would use a simple cube shape to cut the clean surface out and continue just as previously stated. But it needed an inner circle extruded inside itself and that took priority as there would be a face issue to extruded inwards an circle if the face was not a circle.


From the example above you can see the end result. I have given a visual example of what i had done to create the top area of the cylinder.

1. Extrude another circular face into the cylinder.
2. Cut a cube out of it (shown by a grey box).
3. Extrude the upper flat surface up and transform the vertices closer together on the x-axis.
4. Push the smaller circular face in using the extrude tool.
