About this Book

      Cheryl Shrock and co-author Steve Heather are always trying to think of new ways to make it even easier to learn and use AutoCAD. And the AutoCAD® Pocket Reference, 8th Edition, is one of the best quick reference tools available for this purpose. It includes all the important fundamental commands, concepts, and how to information for the every day use of AutoCAD® 2018 or AutoCAD® 2019. It is not designed to take the place of larger textbooks but rather to supplement them as a quick reference.

How to use this Book

      The information in this book has been organized in 13 sections. Each section contains related material. For example, if you needed information regarding dimensioning, you would go to: Section 3: Dimensioning.

      AutoCAD has two color themes, Light and Dark. The Light color theme has been used throughout this book. To change the color theme refer to Appendix B.

      This reference book was created using AutoCAD 2019. There are some cosmetic changes, such as the look of the buttons between AutoCAD 2018 and AutoCAD 2019, but the commands are the same.

Section 1 Action Commands

Array

      The Array command allows you to make multiple copies in a Rectangular or Polar (Circular) pattern and even on a Path. The maximum limit of copies per array is 100,000. This limit can be changed but should accommodate most users. (Refer to the Help Menu if you choose to change the limit.)

       Rectangular Array

      This method allows you to make multiple copies of object(s) in a rectangular pattern. You specify the number of rows (horizontal), columns (vertical) and the spacing between the rows and columns. The spacing will be equally spaced between copies.

      Spacing is sometimes tricky to understand. Read this carefully. The spacing is the distance from a specific location on the original to that same location on the future copy. It is not just the space in between the two. Refer to the example below.

      To use the rectangular Array command you will select the object(s), specify how many rows and columns desired and the spacing for the rows and the columns.

      Refer to step-by-step instructions on page 1-3.

       Example of a Rectangular Array:
