How are CAD parts assembled and rendered to present a finished product?

CAD assembly and rendering: combining component models into an assembly, producing exploded views and illustrations, and applying materials, lighting and rendering to present a product realistically.
An SQA National 5 Graphic Communication answer on CAD assembly and rendering, covering how separate component models are combined into an assembly, exploded and illustration views, and how materials, lighting, textures and rendering produce a realistic presentation of a product.

How does perspective drawing create a realistic sense of depth using vanishing points?

Perspective drawing: one-point and two-point perspective, the horizon line and vanishing points, and how perspective gives the most realistic impression of depth.
An SQA National 5 Graphic Communication answer on perspective drawing, covering one-point and two-point perspective, the horizon line and vanishing points, how parallel edges converge to give a realistic sense of depth, and when each type of perspective is used.

How do isometric, oblique and planometric drawings show a product in three dimensions?

Pictorial drawing in isometric, oblique and planometric projection: the angles each uses, how depth is shown, and when each pictorial method is the most useful.
An SQA National 5 Graphic Communication answer on pictorial drawing, covering isometric projection at 30 degrees, oblique projection with a flat front face, planometric projection from a rotated plan, how each shows depth, and when each pictorial method is most useful.
