Vector Entity

The Vector Entity stucture.

The vector entity structure will vary depending on the vector type.

// Line type
entity = {
    type : 0, //a number indicating the vector type,
    handle : //a unique value identifying the vector entity,
    typename : "LINE", //a string indicating the vector type,
    length : number, //the length of the line
    startpoint : {x:number , y: number},//the start point of the line, 
    endpoint : {x:number , y: number},  //the end point of the line, 
};

// poly line type
entity = {
    type : 1, //a number indicating the vector type,
    handle : //a unique value identifying the vector entity,
    typename : "LWPOLYLINE", //a string indicating the vector type,
    length : number, //the combined length of all lines in the poly line,
    area : number,//the area of the poly line, 
};

// Arc type
entity = {
    type : 4, //a number indicating the vector type,
    handle : //a unique value identifying the vector entity,
    typename : "ARC", //a string indicating the vector type,
    length : number, //the length of the arc
    radius : number,//the  radius of the arc, 
    sweep : number,  //the  anle of the arc in degrees, 
};

// Circle type
entity = {
    type : 5, //a number indicating the vector type
    handle : //a unique value identifying the vector entity.
    typename : "CIRCLE", 
    length : number, //the circumference of the circle
    radius : number,//the  radius of the circle, 
    area : number,  //the  area of the circle, 
};

// other types

entity = {
    type : number, //a number indicating the vector type,
    handle : //a unique value identifying the vector entity,
    typename : String, //a string indicating the vector type,
};

The types

These are the currently possible vector entity types by type number.
