Projection Types in Engineering and Architectural Drawing: Part 2

Next in our series of projection types in engineering drawing and architecture drawing service is the Multiview projection. Since our inception in the year 2005, we keep getting requirements from our esteemed global clients for Multiview engineering drawing and architecture drawing, usual requirements are for around four to six pictures of a subjected object or a product which are called primary views. Under primary views each projection plane parallel to one of the coordinate axes of the object are represented. The views under Multiview projection are positioned accordingly to either of first angle scheme or third angle scheme.


The appearances of views in Multiview engineering drawing or architecture drawing may be thought of as projected like a box (six – sided) around the object. Again in our experience of working on such Multiview requirements from our global esteemed clients under engineering drawing or architecture drawing, primarily three views like front view, top view and end view provides good enough information to make three dimensional object although the requirements are to work on the six sides of projected box view. As per the standard industrial practice globally we have also observed our esteemed clients referring to these three primary views as elevation, section and plan.


Primarily where more than one side of the subjected object or product are visible in same image and axis of the object or plane depicts is not parallel to the projection plane it is called an auxiliary view. As a result we could consider including isometric, diametric and trimetric projections under auxiliary views in Multiview projection, also a key point to note here is one axis of space is usually displayed as vertical in Multiview projection, this is also one of the key characteristics of an ideal Multiview projection.


Yet another orthographic projection map is classified as the map projection of cartography. Orthographic projection is a perspective, in which the sphere is projected onto a secant plane. The point of perspective depicts a hemisphere as it appears from outer space where the horizon is a great circle.
