3D modelling in OpenSCAD

Abstract

Especially due to the massive expansion of 3D printing technology, it is directly proposed to include the basics of 3D modelling in the curriculum. Secondary school students, especially With relatively modest knowledge, students of secondary schools, especially those with a more technical focus, can carry out their own design of various components and thus better understand the technical principles of construction. In addition, parametric 3D modelling enables pupils to learn the simple basics of programming. In primary schools, it can help develop spatial imagination or serve to demonstrate various mathematical concepts such as geometric shapes, geometric transformations and set operations. In OpenSCAD, we model using a simple programming language (also called OpenSCAD) to describe the process of constructing the resulting object. This gives the designer more control over the object being modelled and allows him to easily change any part of the design. In particular, this makes OpenSCAD a popular choice for designing 3D objects for 3D printing.
