Such an analysis made it possible to choose software systems that most accurately allow for the implementation of the 3D modeling method proposed in the article with subsequent printing on a 3D printer. This method is considered in detail on the example of constructing several types of helicoids. The process of 3D modeling of a helicoid is described step by step and is divided into several stages: parametric modeling of a helicoid in SCAD, editing of the resulting model in AutoCAD and its export to a special format for 3D printing. The use of the method of parametric modeling is due to its accuracy and uncompromisingness. With its help, one can accurately judge the type of the built surface. Parametric modeling is the construction of a surface by compiling equations on each axis, i.e. along the x, y, z axes, and for each type of surface there are specific characteristic equations. It is not possible to implement the method of parametric modeling in all software systems; in this connection, certain difficulties arise. The article analyzes the difficulties encountered in 3D modeling of the helicoid and suggests ways to solve them.</p></abstract><trans-abstract xml:lang="ru"><p>В статье анализируются современные и доступные программные комплексы для построения моделей оболочек сложной геометрии и возможности их применения в 3D-моделировании. Анализ позволил выбрать программные комплексы, которые наиболее точно реализуют предлагаемый в статье метод 3D-моделирования с последующей печатью на 3D-принтере, подробно рассматриваемый на примере построения нескольких видов геликоидов. Процесс 3D-моделирования геликоида описан пошагово и подразделяется на несколько этапов: параметрическое моделирование геликоида в SCAD, редактирование полученной модели в AutoCAD и ее экспорт в специальный формат для 3D-печати. Использование метода параметрического моделирования обусловлено его точностью и бескомпромиссностью, с его помощью можно точно судить о виде и типе построенной поверхности. Параметрическое моделирование - это построение поверхности с помощью составления уравнений по каждой оси, то есть по осям x, y, z , для каждого вида и типа поверхности существуют свои характерные уравнения. Реализовать метод параметрического моделирования можно не во всех программных комплексах, что влечет определенного рода трудности. В статье также представлены возникающие в процессе 3D-моделирования геликоида сложности и предложены пути их решения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>3D modeling</kwd><kwd>helicoid</kwd><kwd>parametric modeling</kwd><kwd>additive technologies</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>3D-моделирование</kwd><kwd>геликоид</kwd><kwd>параметрическое моделирование</kwd><kwd>аддитивные технологии</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">STL (file format).
