How Onshape is Redefining the Manufacturing Handoff with MBD and AI

For decades, the handoff between engineering and manufacturing has been the most fragile point in the product development lifecycle. Organizations reliant on legacy CAD software often underestimate the profound inefficiencies that emerge here. It’s the moment where a 3D design is flattened into static 2D drawings, sent via email as a PDF, and handed off to a supplier who might unknowingly be working off last week's revision.

Miscommunication during this handoff leads to scrapped parts, delayed timelines, and massive cost overruns. In traditional file-based CAD systems, manufacturing data is scattered across drawings, exports, and disconnected spreadsheets, leaving teams to grapple with broken references and manual, error-prone processes.

Onshape prioritizes cloud-native access, integrated PDM, model-based definition (MBD), and machine learning for traditional CAD drawings. Here are three questions answered about improving manufacturing handoff with Onshape:

How Does Integrated PDM Improve Design to Manufacturing Handoff?

Onshape’s built-in product data management (PDM) streamlines the handoff by centralizing all product data. Because PDM is built in, there is no missing product data or metadata. All information flows from the 3D CAD model into the drawing and BOM tables.

How Does Cloud-Native MBD Create a Single Source of Truth for Manufacturing Information?

While MBD isn’t a new concept, executing it within a single source of truth in the cloud is a game-changer for conveying complex designs with contextual clarity.

Instead of translating a 3D model into 2D views just to add dimensions and tolerances, engineering teams can now embed geometric dimensioning and tolerancing (GD&T), surface finishes, and datums directly into the 3D model early in the design process, ensuring adherence to rigorous industry standards like ANSI and ISO.

How does it work:

• Semantic PMI (Product Manufacturing Information): Unlike "dumb" text typed onto a drawing, Onshape’s MBD has deep semantic relations to the geometry. The PMI is mathematically attached to the CAD feature. If a geometric reference changes, the tolerance or datum callout remains correctly linked.
• Smart Inspection Panels: All PMI is automatically organized into a structured, filterable list within Onshape. A manufacturer viewing the model can use this panel for instant cross-highlighting, matching the list item to the exact related geometry in the 3D model.
• STEP AP242 Export: For workflows that require physical file handoffs to specific CAM or inspection software, Onshape’s MBD supports exporting as STEP AP242. This format includes the 3D PMI data, allowing it to be read directly into coordinate measuring machine (CMM) programming and inspection tools.

The impact: Adopting MBD across teams forces design collaboration earlier. Manufacturing engineers have the opportunity to leave feedback and annotations directly on the 3D model while it’s being built. Late-stage ECOs are minimized as a result.

What Does Onshape Do to Speed Up Traditional CAD Drawings?

Even with the rise of MBD, 2D drawings remain a reality for many supply chains and compliance workflows. Onshape hasn't abandoned drawings; instead, we’ve injected them with machine learning to drastically reduce the busywork associated with detailing them.

Introduced in Beta in 2026, Replicate Annotations represents a step forward for AI-assisted CAD drawings.

When creating drawings for similar parts or generating new views, engineers no longer have to start from scratch. Replicate Annotations uses machine learning and probabilistic matching to automatically transfer dimensions, tolerances, layout, and annotation placement from one drawing view to another even across entirely different drawings.

How it works: The AI examines the annotations associated with a source view, understands the geometric context, and intelligently maps those exact detailing standards onto the new view.

The impact: This ensures absolute consistency across a company's documentation and saves hours of tedious, manual dimensioning. (For enterprise security, this ML tool operates without using customer data for external model training).

Digitize Your Manufacturing Handoff

Dufour Aerospace accelerates critical cargo drone delivery with PTC’s Onshape and Arena.

Browser and Mobile Access: Teams (like at Dufour) can find and share fully detailed 2D drawings through simple, secure URLs all searchable and accessible from their cloud-native PLM system: Arena. Manufacturing teams and even suppliers can open these in a web browser, or shop floor workers can view them on tablets.

By centralizing the product definition in the cloud with MBD, automating tedious documentation tasks with AI and machine learning, and providing secure, instant access to the latest data from any device, Onshape is closing the gap between the design office and the shop floor.
