MODELING OF TECHNICAL FORMS USING SOLIDWORKS IN THE COURSE "ENGINEERING GRAPHICS AND CAD SYSTEMS"

Abstract

The proposed method of modeling technical forms by means of SolidWorks when studying the course "Engineering graphics and CAD systems". The work presents a step-by-step organization of modeling technical forms using the SolidWorks graphics package, including remotely in web conference mode in the ATUTOR system.

The sequence of creation of parametric models from separate geometric elements such as a bump, cutouts, holes, rounding, chamfers, etc. is demonstrated. After familiarizing themselves with the SolidWorks user interface and the corresponding toolbars, students work on drawing a sketch of a part, create a new document and a wireframe profile of the future part, the elements of which are lines, circles, arcs, polygons, using the SolidWorks Sketch tool palette. Sketching involves using the relationships of sketch elements and dimensions, as well as learning about the five sketch states. The next stage of modeling is the construction of a solid model using the commands Extruded Bean, Extruded Cutout, Through.

At the final stage, elements such as chamfer, rounding, cut, etc. are inserted into the model. Using the commands of the Display Style tab, the solid model is represented in one of the styles (painted, painted with edges, with invisible lines displayed, without invisible lines displayed, wireframe representation), as well as change the color and optical properties of the created model. A working drawing of details is drawn up for the created model. Students learn the relevant commands and tools (Model View, Section, Local Section, Display Section Face, Autohatching, Display Surface, Expanded View, Local View, Auto Dimensioning). The working drawing is printed together with its solid representation in one of the isometric views.
