In these scenarios, using 2D CAD can streamline the design process and reduce the likelihood of introducing unnecessary complexity. The design of simple mechanical components that can be adequately represented in two dimensions. Layout planning, which focuses on the spatial arrangement of objects in a 2D plane and Schematic design, where the primary goal is to represent the functional relationships between components Not all mechanical design tasks require the level of detail or complexity found in 3D CAD models. The difference is between wireframe drafting and solid modeling.
Technically, all these drafting products we label as “2D” are capable of drafting in three dimensions. There are use cases where 2D still makes sense.
The familiarity and compatibility of 2D drawings make them an enduring choice for these sectors. For example, many smaller machine shops serving SMB (small and medium-sized business) manufacturers still require 2D plans for most contract work.

Why? Possible explanations for the enduring popularity of 2D CAD lies in a threefold cord of practicality:įor many designers and engineers, 2D drafting is more straightforward, making it easier to learn.ĢD CAD requires less computational power than 3D modeling.įinally, 2D CAD software is less expensive than its 3D counterpart, making it an attractive option for smaller businesses and individuals with budget constraints.ĢD CAD also remains the standard for many industry-specific applications where traditional 2D plans continue to be widely used. Despite these advancements, 2D CAD remains a prevalent tool for mechanical design. The move from 2D drawings to 3D models provides new downstream utility for applications such as model-based design, digital twins, and additive manufacturing (3D printing).
Why 2D CAD Remains Popular for Mechanical Design 17 Apr, 2023 By: Cadalyst Staff MCAD Solutions: From legacy data to cost of programs, there are a few reasons why 2D CAD continues to thrive.ĭuring the past two decades, 3D CAD technology has garnered significant attention and investment in research and development.
