Which Views to Present? Orthographic Projection is a method of producing dimensioned working drawings or blueprints of 3-D Objects using a series of related 2-D views of the object to communicate the object's length, width and depth. 0000002112 00000 n These arrangements may be divided into: i. location of the individual answer in relation to the reference planes, and ii. 2- the amount of true dip. startxref Each … It shows the object with a top view, a front view and a side view. Orthographic projection is a method of producing a number of separate two-dimensional inter-related views. Orthographic projections allow us to represent the shape of an object using 2 or more views. 0000001536 00000 n Third Angle Orthographic Drawing - an Example. xref 0000000016 00000 n Top view Right side view Front view Figure 9 —Tee fitting with possible orthographic projection views labelled.

Structural Geology Any plane is defined in space by three parameters: 1- the direction of strike . 845 0 obj<> endobj The angles formed between the horizontal and the vertical planes are called the first, second, third, … These views are drawn mutually at right angle to each other. 0000002888 00000 n Orthographic projection is the latest standard of technical drawing in which different views are projected into different reference planes observing perpendicular to respective reference plane. Dihedral Angle. 3- the direction of true dip (as a general trend). But 3-D projections are often weak in providing adequate details of the object, and there is often some distortion of the object. Orthographic Projection The orthographic projection is a way of drawing an object as seen from three different directions. 2.2.1) The Six Principle Views The 6 principle views of an orthographic projection are shown in Figure 2-2.

Orthographic projection (sometimes referred to as orthogonal projection, used to be called analemma) is a means of representing three-dimensional objects in two dimensions.It is a form of parallel projection, in which all the projection lines are orthogonal to the projection plane, resulting in every plane of the scene appearing in affine transformation on the viewing surface. One of these planes is Frontal, while other is horizontal. 0000003116 00000 n die Parallelprojektion - Projektionszentrum in unendlicher Entfernung, Parallelkreise sind längenfrei orthographic projection [TECH.] The word orthographic means to draw at right angles. u��J��'�{�y˫���2_��1��i6^�! Orthographic projection is a parallel projection technique in which the parallel lines of sight are perpendicular to the projection plane 3-D projections are useful in that they provide an image that is similar to the image in the designer’s mind’s eye.

THIS WAY BOTH PLANES ARE BROUGHT IN THE SAME PLANE CONTAINING VP. the directions should be normal to the respective planes. What is Orthographic Projection? You’ll also see an Isometric view that is sometimes used to give a more visual look. Orthographic Projections • Orthographic Projections are a collection of 2-D drawings that work together to give an accurate overall representation of an object. Sheet 8; Sheet 9; Sheet 10; Sheet 11; Shop. For an orthographic projection, this is a rect-angular solid, as shown in Figure 10.1. In this method, two principal planes are kept perpendicular to each other. <<917DA663C26BC140A32F896FA28647CE>]>> Orthographic Projections. <]>> 0000002640 00000 n these vews are front view , top view and side view. Orthographic projection (also called orthogonal) is the simplest type of projection we'll discuss: it consists of merely projecting points and vectors in a perpendicular fashion onto a plane, as shown in Figure 4.26.As in the case of the mirror transform, we define the plane M by a point Q on the plane and (unit) normal vector û. 0000004543 00000 n Orthographic projection of point, line, plane, surface and object.
