Do you draw pipe elevations and end views as part of your daily AutoCAD use? If so, you've probably spent valuable work time searching through printed materials to find the correct inside and outside diameters of different pipe sizes. An easier way is to create a program using AutoCAD's Visual Basic for Applications (VBA), which automatically draws the elevation or end view of a selected pipe for you, as shown in Figure A. In this article, we'll show you how to set up a VBA program that does just that. This program can increase your productivity and save you the hassle of looking up pipe sizes.
