Co to za solidny Modeling?
Solid modeling is a computer-aided design (CAD) exalogy that constructs three-dimensional objects as matematically complete, volume-filled represents. Unlike surface or wireframe modeling, which ch only describe a shape 's outer shell, solid modeling captures both the interior and exterior of a part, including material density, mas contributives, and internal cavities. This makees it indisable for entering tasks thatter require cate mass, centes, center of ragy, and sts analysis.
