The paper describes the application of augmented reality tools to create an auxiliary interactive tool in the field of design. To mediate it, an application with AR operation based on marker tracking has been designed. The created application works with the mobile devices platform. Two types of markers have been used in the application. To display basic information, buttons with functions are added to the scene, such as part information, rotation and change of position in the X, Y, Z direction. The application runs on a mobile phone, with a built-in camera. The marker is displayed in the drawing's lower left corner. The model is positioned so that it appears above the view of the part in the drawing. The task of the application is to support intelligent tools applicable in the design stage of production preparation, in the creation of drawing documentation.
