Learn to master spatial vision and reconstruct complex figures from their technical projections.
To solve the puzzle, you must understand how the figure looks from three different angles.
The view from the front. Defines the main height and width of the piece.
Shows the side of the figure. Defines depth and height from the side.
The view from above. Defines the width and depth of the base.

Black Line: Confirmed and visible edge.
Gray Line: Construction guide (not part of the final figure).
Dashed Line: Hidden edges not seen from the current angle.
