Hi Amit, why don't you just use a DrawFeature control with a Path handler on a vector layer and listen to the layer's sketchmodified event, checking for feature.geometry.components.length?
var layer = new OpenLayers.Layer.Vector("result"); var control = new OpenLayers.Control.DrawFeature(layer, OpenLayers.Handler.Path); layer.events.on({ sketchmodified: function(evt) { if(evt.feature.geometry.component.length == 2) { control.handler.finalize(); } } ); You will then have the feature on your layer. Nothing else to do. Regards, Andreas.
