Many thanks for sharing these models, I think, that I will use them in my further work with the 3D designing of figures for civil constructions. I like to design such patterns and then print them on my 3D printer. I also use some other design tools, I read this on the engineering site https://engre.co/blogs/articles/top-5-3d-modeling-tools/ you can also read about interesting tools for 3D modeling and wrote to me what do you use for your projects.
