Isometric Drawing is a two dimensional (2D) drawing that represents the 3D piping system. In the figure, the lines which are parallel to these lines are called isometric lines, and those lines which are not parallel to these lines are called Non-isometric Lines. The station plane is the point from which the observer is looking at the card. If some other arc is to be constructed, then the same method is to be adopted. An isometric drawing is one of three types of axonometric drawings they are created based on parallel projection technique. Isometric: The way to draw three dimensional view of an object in which the horizontal edges are drawn on the 30° angle and verticals are perpendicular from horizontal base. Remember to hold the isometric paper so that you can see vertical rows of dots! An isometric drawing is one of three types of axonometric drawings. In an isometric drawing, the object appears as if it is being viewed from above from one corner, with the axes being set out from this corner point. Now draw perpendicular offsets from 45° line up to 30° line which will represent the isometric scale. These make angles of degrees 30, 30 and 90 with the horizontal line. An isometric drawing usually consists of a number of parts that are physically connected so that they form a network such as a pipe run, pipeline or spool, or cableway.

A box is constructed in accordance with these dimensions. it is a type of pictorial projection in this 3-d drawing of an object, in which all three dimensions of all three dimensional axes are an object are shown in one view and mentained at equal inclinations if required, their actual sizes can be with each other. for reading this article. Rich Dad's Cashflow Quadrant: Guide to Financial Freedom. Then the four centers of an ellipse are shown. After this, non-isometric lines, circles, and other curves are drawn. In isometric drawings, the three principal axes make equal angles with the image plane. One is drawn vertically and the other two with the 30° set square either side of it. In the same way, isometric circles are also not the actual circles, but they are elliptic ones: For drawing such circles, first of all, the isometric square is constructed. The term "isometric" comes from the Greek for "equal measure", reflecting that the scale along each axis of the projection is the same (unlike some other forms of graphical projection). In an isometric projection, the plane is placed in such a way that all the, three visible sides of the object make same angle with one another. Isometric drawings are commonly used in technical drawing to show an item in 3D on a 2D page. The view drawn to the exact scale is known as the Isometric View (Isometric Drawing).
