答案1
更新：
要添加箭头和其他内容，您可以像添加节点一样添加，显然您必须定义一个特定的点来离开和到达，在本例中，在 Texla 汽车的绘图中，我在顶部添加了一个点，然后就可以使用从一行到另一行的命令以及一行中的节点了。这是一个基本应用程序的示例。

原来的：
只是为了好玩，并将我的例子改编到你的情况，并指出一些重要的事情，第一件事是你应该尝试根据绘图中心的锚点进行绘制，这样你就可以利用镜像来改变方向; 您还可以定义某些点并为所有情况分配一个 ID; 我将该点保留为每个绘图0.0的坐标，以便以后使用，也是汽车前部的点，以防您想在它们之间制作一个尺寸。
仅通过查看代码来绘制具有复杂形状的东西可能会非常复杂，有很多方法可以绘制像车辆这样复杂的东西，您只需求助于其他免费工具，例如 Inkscape，您可以选择打开 SVG 文件并将其保存为 PDF 格式，然后使用 include 图形将其导入到节点中的绘图中，缩放它并添加点或文本；但是，您将无法更改颜色；为此，您可以做的是跟踪路径，尽量使它们保持最小，然后使用扩展程序将这些笔触导出到 tikz。
您依次获得的笔触必须适应您的绘图大小，幸运的是，您可以使用范围缩放和移动所有点，然后将它们嵌套在定义中，剩下的就是修复问题，修复代码以便可以读取，等等。最终，您会得到一个框架，您可以像使用贴纸一样使用它们。
