What does 2D modeling refer to?

2D modeling specifically refers to the process of creating representations that involve only two dimensions: height and width. This type of modeling is commonly utilized in various fields, such as architecture and graphic design, to create plans, elevations, and other visual elements that capture the physical attributes of objects or layouts without the complexity of third-dimensional depth.

When working with 2D models, designers communicate ideas and intentions through flat representations, often using software tools that allow for precise measurements and details. This approach simplifies the visualization of relationships between various components in a design or construction project.

The other options imply characteristics or methods that pertain either to three-dimensional modeling or different applications altogether. For instance, three-dimensional modeling incorporates depth, which is not a feature of 2D configurations. Similarly, cost estimation strategies are typically not defined by the dimensional aspects of modeling, and virtual representations can suggest a deeper spatial context that goes beyond two dimensions.
