Class: McDbLinetypeTableRecord

2d.McDbLinetypeTableRecord

Represents a line type table that records objects and implements attribute related operation functions for line types.

Example

//Add line type
   import { MxCpp, McDbLinetypeTableRecord } from "mxcad"

   const mxcad = MxCpp.getCurrentMxCAD();
//Get the current line style sheet
   let linetypeTable = mxcad.getDatabase().getLinetypeTable();
//Construct a new line type table to record objects
   let newLinetypeRecord = new McDbLinetypeTableRecord();
//Set the number of dashed lines for line type objects
   newLinetypeRecord.numDashes = 0.2
//Set the name of the line type object
   newLinetypeRecord.name = "TestMyLine"
//Add line type
   const res = linetypeTable.add(newLinetypeRecord).isValid()
   if (res) {
       console.log("add ok");
   }
