Executing this region’s construction will demand the application of Union, Subtraction, and Intersection Boolean operations. Every model shape you create will have to go through this step, where our model shape will be given mass and the ability to occupy space. When we create a region, we are implying that we want to bring our model shape into existence. The outcome of a modeled 3D object will portray the same physical characteristics applicable to an object existing in the real world. When we fuse CAD with modeling, we have CAD modeling, which facilitates the actual representation of the objects perceived with our eyes or imagination and creates a realistic representation of these objects with specific dimensions. It is because modeling is a study mirrored image of actual objects in the real world. In the world of Computer-Aided Design or CAD, a model is anything visual, analytical, and printable. Before this tutorial article immerses you into the intriguing maze of 3D CAD (Computer-Aided Design) modeling, we should make acquaintance with what modeling really is so that you have a third-eye view of the way you perceive shapes. Alternatively, you are now able to design awesome robotic parts for your engineering projects, or you can just copy-and-paste the world designs that you fancy and think should reside in your modeling portfolio. Now that you have BRL-CAD installed on your Linux system, you have no excuse but to re-pursue your architectural hobby and design that house you imagined in your head.
