Хлопче! не там баг ищешь

package main {
	import flash.display.*;
	import ascb.drawing.Pen;
 
	public class les32 extends Sprite {
 
		//public var sampleSprite:Sprite;
 
		public function les32() {
			var samleSprite:MovieClip = new MovieClip();
                   addChild(sampleSprite);//   !!!sampleSprite!=samleSprite!!!
 
			var pen:Pen = new Pen( samleSprite.graphics );
 
			pen.lineStyle(1);
 
			pen.drawLine( 0, 0, 10, 0 );
			pen.drawLine( 15, 0, 25, 0 );
			pen.drawLine( 30, 0, 40, 0 );
			pen.drawLine( 45, 0, 55, 0 );
		}
	}
}

а так будет визуально видно, что класс работает

package {
	import flash.display.*;
	import ascb.drawing.Pen;
 
	public class PenTest extends Sprite {
 
		//public var sampleSprite:Sprite;
 
		public function PenTest() {
			var samleSprite:MovieClip = new MovieClip();
 
				addChild(samleSprite);
 
			var pen:Pen = new Pen( samleSprite.graphics );
 
			pen.lineStyle(1);
 
			pen.drawLine( 0, 0, 0, 10 );
			pen.drawLine( 15, 0, 25, 0 );
			pen.drawLine( 30, 0, 40, 0 );
			pen.drawLine( 45, 0, 55, 0 );
		}
	}
}
