vdWebLibrary Namespace > ScriptCommands Class : arc Method
parameters
A array of parameters in the following order, used for no user action. 1.Center point in world coordinate system, as an array of 3 numbers(X,Y,Z) 2.Radius in drawing units 3.Start angle in radians 4.End angle in radians
callback
A user function of ScriptEntityDelegate type, that will be called when the command finish successfully.It can be ignored.
Add an arc to the document.

Syntax

JScript 
public function arc( 
   parameters : Object[],
   callback : ScriptEntityDelegate
);

Parameters

Example

C#Copy Code
vdrawobj.scriptCommand.circle(); // begins a user action to draw an arc
C#Copy Code
// draw an arc using active color , linetype,layer etc properties, with center 2,2  radius 3 , start angle 45 degrees and end angle 135 degrees 
//after this command is finished the object is not drawn on screen. 
//You can call the vdrawObj.redraw after adding an amount of commands 
vdrawobj.scriptCommand.arc([[2,2,0],3.0, vdgeo.DegreesToRadians(45), vdgeo.DegreesToRadians(135)]);  
setTimeout(vdrawObj.redraw);//post a redraw command
C#Copy Code
// draw an arc using active color , linetype,layer etc properties,  with center 2,2  radius 3 , start angle 45 degrees and end angle 135 degrees 
//after this command is finished the object is not drawn on screen. 
//In order to display it call vdrawObj.DrawEntity and <see cref="M:vdWebLibrary.vdrawObj.Refresh"/>  inside the user define callback .See example. 
 
function actionentityadded(vdraw, entity) { 
   vdraw.DrawEntity(entity); 
   setTimeout(vdraw.Refresh);//post a refresh command 
            } 
vdrawobj.scriptCommand.arc([[2,2,0],3.0, vdgeo.DegreesToRadians(45), vdgeo.DegreesToRadians(135)] , actionentityadded);

Remarks

if passed parameters not exist or it is null then start a new user action and prompts the user to draw an arc. If parameters are not null then a new arc is added synchronously depend on the passed parameters. The command add the action to undo history and also to script lines getCommands If parameters are not null and after this command is finished the object is not drawn on screen In order to display it call DrawEntity and Refresh inside the user define callback .See example.
