The orthogonal projection on a horizontal plane, which is seen from the top view.
The orthogonal projection on a vertical plane, which is seen from either the side view or the front view.
The following diagram shows a combination of a cuboid and a right prism with rectangle \(ABCD\) on a horizontal plane.
\(ABGHIF\) is a uniform cross section of the object.
\(BH\) and \(FI\) are vertical.
Draw to full scale:
The direction of side elevation (direction \(Y\)) is from left to right.
Thus, the position of the side elevation is on the first quadrant.
The following diagram shows the combination of a cuboid and a right prism.
Sketch the three-dimensional shape of the object.
The position of side elevation is in the first quadrant.
So, the view of the side elevation is from left to right.
This object contains an angle of \(60{^\circ}\)on a triangular surface.
Thus, the angle must be built correctly.
