Danilov // Journal for Geometry and Graphics. – 2014. – Vol. 18. – Num. 1. – P. 115–124.14338157http://eadnurt.diit.edu.ua/jspui/handle/123456789/2649EN: In 3D modeling CAD users often face problems that can be success-fully analyzed and solved only by the methods of Descriptive Geometry. One such problem is considered in this paper: the construction of structural elements of machine parts known as stiffening ribs. In addition, a possible geometry of ribs is analyzed and a review is performed of tools for its modeling available in up-to-date CAD packages. Some features are shown that are useful in representing parts with ribs in technical drawing manuals. An innovative approach is developed for educational purposes.englishCADdescriptive geometrystiffening ribСАПРнарисна геометріяребра жорсткостіначертательная геометрияребра жесткостиScopusскопусКГArticle
