The top view is positioned directly above the front view and for the side view, we generally position the right side view on the right of the front view. As a result, the dimensions are less than the actual ones. Therefore the 2nd angle projection system is not used to draw engineering drawings. There are usually three isoplanes in an isometric drawing: top, right, and left. The isometric drawing is drawn using 100% true length measurements on the height, width, and depth axes. Because the observer normally looks from the right side of the quadrant to obtain the front view, the objects will come in between the observer and the plane of projection. Engineering drawings use standardised language and symbols.

Local vs. [FIGURE 3-2] Projections of the point are made onto three of the surfaces that make up the box: the top or “H” (horizontal) plane, the front or “F” (frontal) plane, and the right side or “P” (profile) plane. The purpose is to convey all the information necessary for manufacturing a product or a part. The main difference between isometric and typical perspective drawings is that in the latter the lines recede to vanishing points. Isometric (meaning "equal measure") is a type of parallel (axonometric) projection, where the X and Z axes are inclined to the horizontal plane at the angle of 30°. Isometric drawing is a 2D drawing that enables a person to get a vision of a 3D view of a line. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Because all edges of an isometric object are inclined at the same angle, they are equally foreshortened.

Do you know the difference between isometric and spool drawing? If you have selected "Iso drawing" - the spool section is used to define spools to be annotated within that iso, and consequently the Isos will split sheets at spool boundaries, but can contain multiple spools. In fact, the major difference is that an orthographic drawing is a two-dimensional representation of an object, with all the views represented in it. On the other hand, in 3D shapes, the three axis x, y and z-axis are covered. Normally you send out the "raw" isometrics to the fab shop and they re-draw them into spools where required.
