OVERVIEW

CHAPTER SUMMARY

In this chapter, you learn how to incorporate standards in a template drawing. You also learn about standard title blocks and drawing borders, as well as in which order to place drawing sheets.

Just as there are international standards for dimensions, there are standards for drawing size, borders, and title blocks. In addition, there is a standard for placing multiple details on a single drawing. The international standards are known as:

• ANSI American (imperial).

• DIN German (metric).

• ISO International (metric).

• JIS Japanese (metric).

Some CAD packages include drawings (called templates) based on these standards.

DRAWING SIZES

When you create a drawing, you draw it full size. Being digital, the size of the drawing doesn't matter. (There is one exception: some CAD packages constrain the maximum drawing size, such as MicroStation up through version J.)

When it comes time to plot the drawing on paper, you are usually constrained to a half-dozen sizes of media, ranging in size from under a foot to about 4 feet wide.

In imperial measurements, the sizes are called A (the smallest) through E (the largest). There are additional special purpose sizes, such as the extra-long J-size used by the aircraft industry.

In the metric world, the sizes are called A0 (the largest) through A4 (the smallest).

While there are variations of each size (engineering, architectural, and metric), they all have one thing in common: each larger size doubles the paper area. For...
