Abstract:

Digital models of 3D objects are a suitable tool for supporting distance education of technical subjects at secondary and primary schools. They make it possible to illustrate in detail not only very complex components, but also entire objects and functional units. Moreover, digital models can be animated, which facilitates the understanding of very complicated functioning of the device. Digital modelling allows to create photorealistic visualizations, animations, and interactive presentations based on 3D CAD models of engineering equipment. It can be helpful in the fields of technological units, architectural projects, interior design, and other areas of human activity. Such already completed projects can be applied in teaching. Another possibility is the creation of digital 3D models by the students themselves with the support of the teacher using one of the e-learning platforms. Many different software products are available for this activity. The current trend in teaching is to work in an online cloud application environment. When creating digital models, it is necessary to consider the age structure of students and their previous skills and experience. This work presents the practical use of 3D models in the distance teaching of technical subjects at secondary and primary schools. The method of direct online model creation by the teacher using parametric 3D CAD modelling SW and the method of direct online model creation by the student with the remote support of the teacher were used. 3D models created in this way were then physically printed on a 3D printer using the FDM method.
