With the continuous development of weather cause, the problem of human shadow safety is getting more and more attention. The 37 mm anti-aircraft gun weather modification operating point code for safety of forms graph (QX/T 256-2015) on May 1, 2015 implementation of the specification to 37 mm anti-aircraft gun safety forms figure made detailed provisions. After investigation, county (city) level figure unit how to use Photoshop or CoralDraw mapping software map area of fire safety, the use of these software map area of fire safety, a common shortcoming in the drawing ratio is difficult to control, drawing operation is complicated, the production process takes longer, especially drawing fan area and its accurate positioning is difficult. Some units use the method of outsourcing, which makes it difficult to proofread the work, and the drawing quality is difficult to guarantee. This paper introduces the steps and methods of using AutoCAD to draw the safe shooting map of weather operation point. Use AutoCAD can quickly and accurately implement security forms the bitmap, operation is simple, easy to use, especially in the proportion control, precise positioning of incomparable advantages have other drawing software.
