As a designer or drafter we need to know the correct projection of the orthogonal views in drawings there are two projection methods: first angle and third angle. Third angle projection is a method of orthographic projection which is a technique in portraying a 3d design using a series of 2d views an alternative method to third angle projection is first angle projection different countries and regions typically use one method or the other although this can depend on a company's customer.
Re: third angle projection deepak gupta may 9, 2012 1:35 am (in response to tony kirkpatrick) might be possible using a macro but i would also suggest you to keep two different drawing templates: one for each first and third angle, so that the chances of errors are almost nil.
