6. 系统变量
系统变量
CAD 系统变量是在计算机辅助设计(CAD)软件中使用的一种设置。 CAD 系统变量可以控制 CAD 软件的行为、外观和功能。它们可以是全局变量,用于控制整个 CAD 系统的行为,也可以是局部变量,只对特定的 CAD 对象或操作起作用。
CAD 系统变量可以控制各种参数,例如图形显示的单位、精度和颜色,绘图对象的默认属性,工具栏和菜单的布局,以及各种命令的行为。通过修改系统变量的值,用户可以根据自己的需要调整 CAD 软件的功能和外观。
每个 CAD 软件都有自己的一套系统变量,并且可以根据需要添加新的系统变量。用户可以通过设置 CAD 软件的选项或使用相应的命令来修改系统变量的值。
mxcad也提供了对应CAD变量的获取和设置方法。
根据不同的变量类型, 我们分了四种不同方式设置:
获取浮点数变量getSysVarDouble,
获取长整数变量getSysVarLong
获取点变量getSysVarPoint
获取字符串变量getSysVarString
设置就是方法的get
改成set
, 传入变量名和对应类型的值。
动态捕捉相关的系统变量
举一个应用系统变量的例子
示例项目: https://demo.mxdraw3d.com:3000/mxcad/
最右下方按钮开关,它们都是长整数系统变量:
export enum SysVarLongSketchSettings {
/** 栅格 */
GRIDMODE = "栅格",
/** 正交 */
ORTHOMODE = "正交",
/** 极轴 */
AUTOSNAP = "极轴",
/** 对象捕捉 */
OSMODE = "对象捕捉",
/** 对象追踪 */
DYNTRACE = "对象追踪",
/** DIY */
DYNINPUT = "DYN",
/** 线宽 */
LWDISPLAY = "线宽"
}
除了OSMODE
对象捕捉变量, 其他变量设置的值都是0
表示关闭, 1
表示开启
import { MxCpp, McGePoint3d } from "mxcad"
const mxcad = mxcad.MxCpp.getCurrentMxCAD()
// 开启栅格
mxcad.setSysVarDouble("GRIDMODE", 1)
// 开启正交
mxcad.setSysVarLong("ORTHOMODE", 1)
// 关闭线宽
mxcad.setSysVarLong("LWDISPLAY", 0)
而动态捕捉, 因为存在各种捕捉, 需要多个开关, 我们获取到的动态捕捉值, 是根据这些开关是否开启运算得到的总值。
因此我们需要设置动态捕捉的开启关闭,各种捕捉是否开启, 代码如下:
import { MxCpp, McGePoint3d } from "mxcad"
const mxcad = mxcad.MxCpp.getCurrentMxCAD()
const osModeVal = mxcad.setSysVarLong("OSMODE")
export enum SysVarLongSketchSettingsOsMode {
/** 端点捕捉 */
End = 1,
/** 中点捕捉 */
Mid = 2,
/** 圆心点捕捉 */
Cen = 4,
/** 节点捕捉 */
Node = 8,
/** 象限点捕捉 */
Quad = 16,
/** 交点捕捉 */
Int = 32,
/** 插入点捕捉 */
Ins = 64,
/** 垂足点捕捉 */
Perp = 128,
/** 切点捕捉 */
Tan = 256,
/** 最近点捕捉 */
Near = 512,
/**外观交点捕捉*/
App = 2048,
/**延伸点捕捉*/
Ext = 4096,
/** 平行点捕捉 */
Par = 8192,
/**捕捉关闭 */
Off = 16384,
}
// 关闭捕捉 0 或 1
const osModeOff = osModeVal & SysVarLongSketchSettingsOsMode.Off
// 平行点捕捉 0 或 1
const osModePar = osModeVal & SysVarLongSketchSettingsOsMode.Par
// 是否开启平行点捕捉
const isOpenOsModePar = true
// 设置
mxcad.setSysVarLong("OSMODE",
isOpenOsModePar
?
(osModeVal | SysVarLongSketchSettingsOsMode.Par)
:
(osModeVal & ~SysVarLongSketchSettingsOsMode.Par)
)
// 其他捕捉开关设置与上面代码一样
// ...
通过上述代码运行, 这是固定的规则。
在CAD存在各种各样的变量,我们只需要通过调用mxcad提供的这几个方法就可以设置它们。
