Draw a convincing object from imagination

Draw an invented object with consistent structure, perspective, volume, proportion, and line control.

What it is

This capstone combines drawing, perspective, and form. You build a 3D object from simple shapes, show volume through overlaps and foreshortening, and keep that volume consistent.

You set the proportions of each part, show how the parts fit together, and consider how the object would function without copying an existing design.

You use controlled lines to describe the object from a chosen angle. You simplify the drawing while keeping its forms readable.

You can check it when

• ✓Sketch an object you have not seen before from a clear angle. Check that it reads as a solid object without tracing or pasting parts from photos.
• ✓Redraw the same invented object from a different angle. Compare the proportions and structure to check that it remains the same object in 3D space.
