Isometric Drawing with Horizontal and Vertical Faces – Subtractive Technique

Intermediate difficulty practice isometric drawing with all normal horizontal and vertical surfaces, completed using a subtractive technique. The hidden lines on the given orthographic projection make it difficult to determine whether features are protrusions or holes, so this isometric handsketching example starts with drawing a bounding box, then visible features, then moves to ambiguous hidden features last.
