GRAPHIC MODELING IN THE COURSE "ENGINEERING GRAPHICS AND CAD SYSTEMS" USING AUTOCAD AND SOLIDWORKS GRAPHIC PACKAGES

Abstract

The method of graphic modeling in the course “Engineering Graphics and CAD Systems” using the graphic packages AutoCAD and SolidWorks is considered. A combination of these tools is proposed when studying the course “Engineering Graphics and CAD Systems” on the example of specific tasks performed by students, including remotely in the web conference mode in the ATUTOR system. Students begin the course by mastering the basics of descriptive geometry. These are positional and metric tasks that are conveniently performed using AutoCAD tools, creating 2D drawings. Depending on the specialty, students perform tasks in AutoCAD related to the creation of 2D drawings of architectural plans, electrical diagrams, and scans, and also make quick 2D sketches that are used at the final stage of 3D modeling in SolidWorks. At the same time, students master the basics of geometric modeling, operating with lines, arcs, and other primitives.

In SolidWorks, students create 3D models of parts (Parts), which are assembled into assemblies (Assemblits), based on which drawings (Drawings) are automatically generated. These tasks are “Projection Drawing”, “Gear Making”, “Welded Joints” and “Detailing of Assembly Drawing”.

The tasks “Rigi. Threaded parts”, “Projections with numerical marks”, “Riveted joints”, “Floor plan”, “Building section” are performed using AutoCAD. During the tasks, students master the strengths of both graphic editors, acquire skills in their rational use, which they will use in future engineering activities.

Our course “Engineering graphics and CAD systems, as well as its electronic version” allows students (including remotely) to master the methods of designing and producing drawings, combining AutoCAD and SolidWorks tools and be competitive in the modern labor market.
