Place the spectator point S, which is 16m from point A on the drawing. The picture plane should be positioned such that it touches point A, ensuring that the drawing perspective originates accurately relative to the viewer's position.

Identify the vanishing points required for the perspective drawing. The primary vanishing point will align with the horizon line which is 7m above the ground line. Additional auxiliary vanishing points may be established to help in drawing inclined surfaces B and C.

In the elevation drawing, delineate the ground line across the plan. Establish the horizon line at 7m height and note the position of both the primary and auxiliary vanishing points, ensuring they are accurately measured and positioned relative to the spectator point.

Translating the coordinates of the corner A into a perspective view involves measuring its height and depth in relation to the spectator point, ensuring the angles and lines connect accurately with the respective vanishing points.

Create the base lines of the structure using the established vanishing points to set dimensions for surfaces B and C. Maintain accurate proportions relative to the observer's perspective, indicating depth appropriately.

Incorporate a height of 70mm from the base to establish the three vertical surfaces of the coffee-dock accurately, connecting them to the base structure using the appropriate vanishing points to maintain perspective.

Apply a height of 25mm for the horizontal shelf, ensuring it aligns properly with the vertical surfaces previously drawn. Use the vanishing points to accurately depict the depth of the shelf within the perspective view.

To create the opening, apply a height of 10mm. Ensure the perspective is maintained by accurately connecting the opening to the pre-drawn surfaces, utilizing the vanishing point for dimensional accuracy.

Utilize the auxiliary vanishing point to define the sloping surface B. Ensure that the slope is correctly depicted in the perspective drawing, maintaining the incline as indicated.

Similarly, use the auxiliary vanishing point to accurately draw the sloping surface C, ensuring that it matches the specifications provided and accurately reflects the intended perspective.

Finalize the perspective drawing by detailing the surfaces and ensuring all elements are proportionate to the spectator point. Review the drawing for accuracy, ensuring that all lines converge correctly at the vanishing points and give a clear dimensional view of the coffee-dock.
