Description: An end cap is a geometric shape used to close the ends of a 3D object. This element is crucial in three-dimensional modeling, as it provides a clean and complete finish to the modeled structures. End caps can take various shapes, such as circles, squares, or polygons, depending on the geometry of the object they are applied to. Their main function is to seal or close an object, which not only enhances its aesthetics but can also be essential for the model’s functionality, especially in 3D printing applications. In the context of design, end caps allow designers to maintain the integrity of the model, preventing issues such as loss of volume or the creation of unwanted surfaces. Additionally, in 3D modeling software, end caps are tools that simplify the process of closing open geometries, facilitating the creation of complex objects. In summary, end caps are fundamental components in 3D modeling, contributing to both the appearance and functionality of the created objects.
