October 19th‚ 2013 1A Orthographic vs. Isometric By Adam Almassri If you’ve ever seen a drawing where the three dimensions of the object in the drawing are represented in three seperate views‚ where each view shows one of the three planes from the object‚ that means you’ve seen an orthographic drawing. Now if you’ve ever seen a drawing where the 3D drawing shows all three of height‚ width‚ and depth of the object in a single perspective‚ and the viewpoint being at a 45 degree angle

PROJECTIONS The engineering drawing is a set of conventions for the representation of object with technical purposes (design‚ production).For that‚ we use graphical projections. GRAPHICAL PROJECTION: The production of a two dimensional image of a three dimensional object. HISTORY OF PROJECTIONS: Throughout human history we have used pictures to convey ideas‚ express ourselves‚ present information‚ etc. Basically we have used pictures to communicate. The difference in drawings across time

Trend projection method is a classical method of business forecasting. This method is essentially concerned with the study of movement of variable through time. The use of this method requires a long and reliable time series data. The trend projection method is used under the assumption that the factors responsible for the past trends in variables to be projected (e.g. sales and demand) will continue to play their part in future in the same manner and to the same extend as they did in the past in

that any development intervention that do not take the needs‚ conditions‚ aspirations and aims of the populace into considered can be considered as myopic. Since planning is concerned with the future‚ policy makers and planners require justified projections which provide information about the future size‚ structure and distribution of the population. Therefore effective development planning depends upon the natural knowledge of the composition‚ growth and movement of the population. It is therefore

Dimensioning Fundamentals By William Bussard‚ March 2004 Terminology * Dimension lines: Lines located between extension lines ending with an arrow and to include a numerical value. They should be spaced uniformly approximately .375 to .500 inches apart. * Extension lines: Extend away from a view to indicate a size or location constraint origin. When extension lines cross object or extension lines‚ no gap in either line should be made. * Leader Lines: Lines drawn at an angle (never

through the machine. Orthographic projection (or orthogonal projection) is a means of representing a three-dimensional object in two dimensions. It is a form of parallel projection‚ where 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. It is further divided into multiview orthographic projections and axonometric projections. A lens providing an orthographic projection is known as an (object-space)

Astral Projection Astral projection or astral travel is an interpretation of out-of-body experience (OBE) that assumes the existence of an astral body separates from the physical body and capable of traveling outside it. Astral projection or travel is the astral body leaving the physical body to travel in the astral plane. The idea of astral travel is rooted in common worldwide religious accounts of the afterlife. In which the consciousness or soul journey is described in as an out-of body experience

Understanding Projection & Views Orthographic Projection Orthographic Projection is a way of visualizing different views of an object from there different sides such as a top view‚ front view‚ side view‚ the object is rotated so that the viewer viewing the object can see each individual side as the part is rotated. These Views are then drawn on a sheet of paper‚ enough views are drawn of the object to Help the person manufacturing the part to get a good visualization of what the part looks Like
