Autocad SCR文件绘制折线-结果不一致

Question

我正在使用AutoCAD Civil 3D 2018并具有一个.scr文件，该文件仅绘制了几行（从excel文件生成），但是当我将.scr拖到图形上时，发现结果不一致。 50％的时间符合我的预期，其余时间某些行未显示或结束坐标不正确。

我已经附上了两张图像，显示了我所看到的差异，第一张图像是我所期望的，第二张图像显示了在未正确导入时的外观。

我可以将其拖动到一个空的图形中，有时它会正确显示。如果然后删除这些行并再次将.scr文件拖入，它将始终显示不正确。

起初我虽然是因为在行尾有一些错误的空格，但并没有出现。

有人可以帮助我了解这里发生的事情吗？

非常感谢

李

Answer 1

通过AutoCAD脚本（.scr）或AutoLISP程序（.lsp）向命令提示符提供点时，这些点将受评估时激活的任何对象捕捉模式的影响。

有三种方法可以避免这种情况：

1。禁用对象捕捉

在运行脚本之前完全禁用对象捕捉（通过切换 F3 [从而切换16384系统变量的OSMODE位]或存储当前OSMODE系统变量的值，然后将其设置为0）。

2。 “ _non”对象捕捉修改器

使用“对象捕捉”修改器_none或_non来开始输入点，指示AutoCAD忽略提供的下一个点的任何活动的“对象捕捉”模式，例如：

-color Green pline _non 603913.8394,7570974.6134 w 15 15 _non 603950.7455,7570959.1881

3。 OSNAPCOORD系统变量

将OSNAPCOORD系统变量设置为1。

此系统变量确定在命令行输入的坐标是否会受到活动对象捕捉模式的影响：

0   Running object snap settings override keyboard coordinate entry
1   Keyboard entry overrides object snap settings
2   Keyboard entry overrides object snap settings except in scripts
