List of the Top AI CAD Tools for Onshape in 2026

Prism is Navier AI's innovative desktop solution designed specifically for engineering teams in hardware, mechanical, aerospace, and other fields. This all-encompassing platform merges parametric CAD, 3D visualization, physics simulations, code editing, and reporting tools, all seamlessly integrated into one application. Users can describe a part or project through natural language, create or modify CAD models, and utilize AI agents to manage physics solvers, write scripts, analyze results, and generate visual outputs like plots, dashboards, and reports. The extensive range of solvers includes 12 different families, featuring prominent choices such as OpenFOAM, SU2, CalculiX, Elmer, Project Chrono, and OpenModelica, along with Navier AI’s own Ferro solver. Engineers can effortlessly import STEP files, assess scripts, evaluate meshes, and input parameters for solvers while running multiple agents at once to explore various design possibilities. Prism supports Windows, macOS, and Linux platforms, allowing local solver workflows to be executed directly on the user's device. The application requires an internet connection for its agent, which sends processed information back to Navier AI’s backend model for further analysis. Furthermore, users have the choice to harness cloud computing resources for executing approved solver tasks, significantly boosting flexibility and efficiency in their engineering workflows. This blend of capabilities not only enables engineers to streamline their processes but also enhances the quality of their design results, making it an essential tool for modern engineering challenges.

Free designers from tedious and repetitive tasks that sap their time and creative spirit. The task of creating detailed drawings can be arduous and error-prone, taking away precious hours that would be better allocated to impactful work instead of mere rote activities. Traditional methods of producing 2D fabrication drawings often lead to considerable time loss, which can extend project timelines and increase operational costs. Skilled engineers often find themselves trapped in these dull drawing assignments, preventing them from directing their attention to the more complex and innovative aspects of their projects. Additionally, the manual approach to drawing is susceptible to human mistakes, which can create discrepancies and inaccuracies that result in significant manufacturing challenges later on. As a result, delays in the design and drafting process can cause production lines to come to a standstill. Teams strive to keep their manufacturing processes running smoothly and continuously to maximize overall efficiency. DraftAid addresses the friction and errors linked to drawing, fostering a more efficient workflow. By integrating seamlessly with your existing CAD software, DraftAid enhances your current practices while empowering designers to concentrate on what truly counts. It not only simplifies the drawing process but also markedly increases both productivity and accuracy in design workflows. Ultimately, by alleviating the burdens of manual drawing, teams can achieve faster project completions and a more innovative approach to design challenges.

Adam is an AI-powered CAD tool built to rethink how designers interact with traditional CAD software. It acts as an intelligent agent that performs modeling tasks using natural language commands instead of manual, step-by-step operations. Users can quickly edit parts by describing what they want, eliminating the need for granular clicking. Adam leverages selection context to apply high-level instructions directly to relevant geometry. It enhances feature tree management by detecting duplicated or inefficient features and merging them automatically. Parametrization tools help convert unstructured models into clean, variable-driven designs. These parameters cascade throughout the model, making future edits faster and more reliable. Adam integrates seamlessly into existing CAD platforms, preserving familiar workflows. It is designed to reduce complexity that has accumulated in traditional CAD tools over decades. The AI-native approach lowers the barrier to advanced modeling techniques. Adam supports faster prototyping, iteration, and manufacturing readiness. Overall, it brings modern AI efficiency to long-standing CAD workflows.
