**Example 4**:

The diagram above shows a solid consisting of a right prism and a
half-cylinder which are joined at the plane HICB. The base
ABCDEF is on a horizontal plane. The rectangle LKJG is an
inclined plane. The vertical plane JDEK is the uniform cross-section of the prism.
AB = CD = 2cm. BC = 4cm. CM = 12cm.

Draw to full scale

(a) The plan of the solid

(b) The elevation of the solid on a vertical plane parallel to ABCD as
viewed from X.

(c) The elevation of the solid on a vertical plane parallel to DE as
viewed from Y.
