Three-Dimensional Figure A three-dimensional figure is a shape whose points do not all lie in the same plane.

Prisms and Cylinders. A prism is a polyhedron with exactly 2 congruent parallel faces. The bases are the two congruent parallel faces. Lateral faces are.

ISOMETRICS Isometric means “equal in measure” and refers to the fact that the three receding axes are tilted at 30°. Isometric drawings are constructed.

Presentation transcript:

Patterns and Developments Patterns are used in many types of product designs and forms of manufacturing. The packaging industry makes extensive use of patterns.

What is a development? A pattern of a shape that is laid out in a single flat plane in preparation for bending to a required shape,

Surface Developments Parallel Line Radial Line Triangulation

Extra material used to connect the pattern into the desired shape. Laps and Seams Extra material used to connect the pattern into the desired shape.

Single curved surface (cylinder) Double curved surface (sphere) Plane surface (box) Single curved surface (cylinder) Double curved surface (sphere)

Parallel Line Development All lines are parallel and perpendicular

Truncated Prism Create an auxiliary view to get the true size and shape of the inclined plane.

Oblique Surface Use Triangulation to get the true size and shape of the inclined surface.

Truncated cylinder Again create an auxiliary view Divide the circle and project to the incline Then project to the right side view
