Hello, <\/p>\n

I have to verify before launch a function if a point on a cuve or on an edge is available. <\/p>\n

I start with the Sample exmple, PolygonMesh.cs: <\/p>\n

protected override void OnUpdate(Command command) {
            command.IsEnabled = Window.ActiveWindow != null && Window.ActiveWindow.ActiveContext.SingleSelection is IDesignBody;
        } <\/p>\n

        protected override void OnExecute(Command command, ExecutionContext context, Rectangle buttonRect) {
            Window window = Window.ActiveWindow;
            if (window == null)
                return; <\/p>\n

            var desBody = window.ActiveContext.SingleSelection as IDesignBody;
            if (desBody == null)
                return; <\/p>\n

            DesignBody desBodyMaster = desBody.Master; <\/p>\n

 <\/p>\n

But I don’t understand. <\/p>\n

I try to undertand thanks to theAPI, but the description are to light for me. <\/p>\n

 <\/p>\n

Could you give me explanation ? <\/p>\n

Regards. <\/p>\n","protected":false},"template":"","class_list":["post-254962","topic","type-topic","status-closed","hentry","topic-tag-ansys-discovery","topic-tag-scripting","topic-tag-selection"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
