Model building is the process of creating a physical or virtual representation of an object or system. It can provide a visual guide to help understand complex concepts or improve communication between individuals. Some synonyms for the term might include prototyping, constructing, crafting, manufacturing, or fabricating. These words convey the idea of taking raw materials or ideas and transforming them into something tangible. Other possible synonyms could include modeling, simulation, or testing. Each of these words implies a different type of model building process, from creating a 3D model on a computer to testing the physical properties of a prototype design. Ultimately, the selection of synonyms depends on the context and specific goals of each model-building project.
