Constructors
constructor
• new MxCADSelectionSet()
构造函数
Example
import { MxCADSelectionSet } from "mxcad";
let ss = new MxCADSelectionSet();Overrides
Properties
imp

Inherited from
isSelectHighlight
• isSelectHighlight: boolean = true
选择是否高亮
Example
import { MxCADSelectionSet } from "mxcad";
let ss = new MxCADSelectionSet();
ss.isSelectHighlight = true;isWhileSelect
• isWhileSelect: boolean = true

dxf0
• get dxf0(): string
