TLF ID L1059
Transform 2D shapes to make 3D objects. Match part of a complex object. Start with a shape such as a crescent, T-shape or pentagon. For example, spin a cross shape around its central axis to form a wheel-like block or extrude it to form a prism. Choose a shape and imagine it being spun around an axis or extruded. Picture which 3D block your 2D shape will make. This learning object is the most difficult in a series of six objects.
