Constraints are rules applied to sketches to control the size, shape, and relationship between sketch elements. Three-dimensional figures are referred as solids. SOLIDS- are bounded by the surfaes that contain them. these surfaces can be one of the ff; a surface that is a plane, where a plane is a flat 2-dimensional surface that is straight in two directions. A single curved surface has its radius in one plane. A doubled curved surface has its radii in two planes. A hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen Dimension line - a thin, solid line that shows the extent and direction of a dimension. Center lines are used to indicate the centers of holes, arcs, and symmetrical objects. Phantom lines can show how an object is related to the position of another object  Contours of an object are the main outlines that separate it from the surrounding space. Positive Space Negative Space -is the space -is the occupied by the unoccupied object space around it. Orthographic Projection is a way of drawing an 3D object from different directions. Usually a front, side and plan view are drawn so that a person looking at the drawing can see all the important sides. Plate #6: Orthographic Projection Draw the object on the right side. Next, create different views of the object on the right side, including: Front view Side view Top/Plan view."
