TABLE OF CONTENTS Sometimes, you need to create dimensioned, multiview 2D drawings, as well as isometric-type drawings, of your 3D models. You work in AutoCAD's paper space mode, rather than in model space mode, to do this. Paper space uses layouts to establish paper and plotting parameters for drawings, and uses floating viewports to establish drawing views in those layouts.
This chapter
explains the role of paper space and describes its properties;
describes how to set up layouts;
tells you how to create floating viewports and how to set them up for making multiview orthographic 2D drawings;
explains the techniques for controlling the appearance and visibility of objects within floating viewports;
tells you how to dimension, annotate, and plot 2D paper space drawings of 3D models.
In the not too distant future, it will be common to send digital data from 3D computer models directly to the machine shop. Then, multiview 2D drawings, with their elaborate dimensions and symbols, will no longer be needed. Now, however, they are still a necessity.
Actually, some paper-based 2D form of mechanical part models will probably always be needed for reviews and documentation. Furthermore, at this time, it is difficult to conceive of any technique that will transform 3D models of buildings and structures into real objects. Controlling the motions of milling machines and lathes is one thing; controlling the placement of two-by-fours and pouring concrete footings is altogether...
