一张完整的建筑图纸包含了很多内容，从设计到施工等，图纸是工程人员交流的语言，看懂图纸是入行的基础，包括图纸上面的图形、代号、符号含义等。
<h2 style="text-align: left; margin-bottom: 10px;">一、常用建筑符号含义示例图</h2>
1、材料类

<h2 style="text-align: left; margin-bottom: 10px;">二<a style="color: red;">方钉百科</a>、请很好记的看图口诀</h2>
给你一张图纸，一定要认真、仔细看，一定要细心，因为图纸出错一点点，直接影响施工。简单重复一下口诀：
1、从上往下看，从左往右看。
2、由外向里看，由大向小看，由粗向细看。
3、图样说明对<a style="color: red;">方钉百科</a>照看，建施结施结合看，设备图纸参照看。
4、先看全局性基本图，后看局部性详图。
