<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;"><span style="color: green;"><span style="color: green;">12、相对坐标:选择直线，关闭正交，输入X轴14，输入逗号，则转换为Y轴，输入Y轴坐标。</span></span></span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;"><span style="color: green;"><span style="color: green;">13、直线：指定起点-拖出方向-输入长度-点击确定</span></span></span></p>
