METHOD OF "SKELETAL STRUCTURES" TO SIMPLIFY THE PARAMETRIZATION PROCESS IN AUTOCAD

Abstract

The article considers the method of "skeletal structures", proposed to simplify the process of parameterization. When parameterizing objects whose shape has more than one contour, there may be some complications, namely: auto-overlay dependencies, or sequential parameterization of the relative position of image fragments, can lead to an excessive number of dependencies, which can lead to inconsistencies when performing parameterization . The proposed method allows you to minimize such inconveniences, reduce the number of superimposed parameters and improve the quality of control over the shape of the object. The stages of parameterization of objects by the method of "skeletal structures" are formulated and characterized and recommendations for its use are given.
 The method of "skeletal structures" was developed and applied in the process of studying the topic "Parameterization" of the course "Engineering and Computer Graphics" at the Department of Descriptive Geometry, Engineering and Computer Graphics of the National Technical University of Ukraine "Kyiv Polytechnic Institute named after Igor Sikorsky". The application of the method on the example of flat parts of complex shape and for the structures used in the study of the topic "Assembly drawing" is demonstrated. As a condition of the task in the topic "Assembly drawing" we used a parameterized folding unit, which students adjusted to the parameters corresponding to the variant of the task, and supplemented the drawing with simplified images of fastening threaded elements made by them in the form of dynamic blocks.
