Advantages and Limitations of Orthographic drawings Advantages Orthographic drawings, when attracted to scale, can be utilized to decide precise measurements. Normally the object is drawn as three separate, related views - Front View, Side View and Plan View. Step-by-step guide to drawing orthographic views You are given the following object to draw �? This uses Third Angle Projection to orient the views. Study the given pictorial sketch or object carefully following the principles of orthographic projection 2. Two widths of lines are typically used on drawings; the thick line width should be 0.6 mm and the thin line Select the necessary views 2. 3. The views are produced by using the fundamental concept of Orthographic Projection - the location of the Spectator (the viewer). Most objects can be fully represented showing a front view, side view, and top (or plan) view. orthographic drawing can be transferred directly to isometric drawing. The top view shows the length and breadth of an object.

Orthographic Projections - Basics 1. Orthographic Projections • Orthographic Projections are a collection of 2-D drawings that work together to give an accurate overall representation of an object. An orthographic drawing presents a “straight-on” two-dimensional view or views of an object as seen from, for example, its front, sides, and top. Drawings - Types 3.

For example object, hidden, and center lines. %���� Two widths of lines are typically used on drawings; the thick line width should be 0.6 mm and the thin line The biggest limitation of orthographic drawings is they represent a single perspective that may not show details hidden from view. The word orthographic means to draw at right angles. To understand Orthographic Projection, think of yourself standing in a mirror room. Use drafting equipment or a straight edge such as a ruler to keep lines straight and views aligned. 2 INTERIOR DESIGN VISUAL PRESENTATION manually, whereas others were computer generated. Orthographic projection, common method of representing three-dimensional objects, usually by three two-dimensional drawings in each of which the object is viewed along parallel lines that are perpendicular to the plane of the drawing. Orthographic projection technique can produce either pictorial drawings that show all three dimensions of an object in one view, or multi-views that show only two dimensions of an object in a single view. endobj Regardless of how drawings and graphics are generated, they are part of a process of discovery, exploration, and cre- x��XKo�6��੠0�[email protected]�C��������=��b��#�� ��wF��L[ ؃ሞ~��7C*��G�p�9RrG���hN�x��;�����O��#�#yo�q�;�pnב�ӻ����n Using a soft pencil and a sheet of grid paper, sketch the corresponding orthographic views of the isometric pictorials on the following pages.
