Sentra Now Supports Solidworks 3D CAD Files – Protecting the Digital Blueprint in the Age of AI
Walk into any advanced manufacturing, aerospace, defense, or industrial design shop and you’re just as likely to see Solidworks as you are AutoCAD. The models, assemblies, and drawings built in Solidworks are the digital blueprints for everything from turbine blades and medical devices to satellites and weapons systems.
Earlier this year we announced native support for AutoCAD DWG files, making an entire class of previously opaque CAD data visible to security and compliance teams for the first time. Now we’re extending that same deep visibility to Solidworks 3D CAD files, so you can protect the IP and regulated technical data hiding inside your .sldprt, .sldasm, and related content—without slowing engineering down.
And as AI accelerates design cycles, that visibility is no longer optional.
AI is Supercharging Design – and Expanding the Blast Radius
Design teams are pushing faster than ever:
- Generative design tools propose entire families of parts and assemblies.
- Copilots summarize requirements, suggest changes, and draft documentation off CAD models.
- PLM-integrated agents automatically create downstream artifacts—quotes, NC programs, service manuals—based on 3D designs.
- RAG-style internal assistants answer questions using a mix of project docs, CAD files, and simulation outputs.
All of this is powerful. It also multiplies the ways sensitive CAD data can leak:
- Entire assemblies uploaded to unmanaged AI tools “just to explore options.”
- Export-controlled models referenced in prompts and ending up in long‑lived AI data lakes.
- Supplier and customer CAD shared into external copilots with little visibility into who—or what agent—can access it.
- Rich metadata from CAD (usernames, project codes, server paths, partner names) silently turned into reconnaissance material.
If you don’t understand what’s inside your CAD, where it lives, and which identities and AI agents can reach it, AI doesn’t just speed up design—it speeds up IP disclosure, compliance failures, and supply‑chain exposure.
CAD Has Been a Blind Spot for Security
Most traditional DSPM and DLP tools still treat specialized engineering formats as a big binary blob: “probably sensitive, treat with caution.” That may have been acceptable when CAD lived on a handful of on‑prem engineering servers.
It’s not acceptable when:
- Decades of CAD history have been lifted and shifted into S3, Azure Blob, or SharePoint.
- ITAR/EAR “technical data” now lives side‑by‑side with everyday project files in cloud object stores.
- Those same repositories feed downstream systems—PLM, MES, AI assistants—where traditional security tools have little or no visibility.
We built native DWG parsing into Sentra to break that stalemate, making CAD content as transparent to security teams as a Word document. Solidworks 3D CAD support is the next logical step.
What’s Really Inside a Solidworks 3D CAD File?
Like DWG, a Solidworks file is far more than geometry. It’s a container for rich metadata, text, and structural context that describes both what you’re building and how it fits into regulated programs and commercial IP. Our Solidworks support is designed to surface that security‑relevant context—without requiring CAD tools, manual exports, or data movement.
Similar to what we do for DWG, Sentra can extract and analyze key elements, including:
- Document properties
Authors, “last saved by,” creation and modification timestamps, total editing time, and revision counters—signals that help you understand who is touching sensitive designs and when.
- Custom properties and configuration metadata
Project IDs, part and assembly numbers, revision codes, program names, business units, and export‑control or classification markings encoded as custom properties or notes.
- Text content and annotations
Notes, callouts, PMI, and embedded text that often contain material specifications, tolerances, customer names, contract IDs, and phrases like “COMPANY CONFIDENTIAL,” “EXPORT CONTROLLED,” or ITAR statements.
- Assembly structure and component names
Which parts roll up into which assemblies, and how those components are named—critical when you need to understand which physical systems a given sensitive model belongs to.
- File dependencies and paths
References to drawings, configurations, libraries, and external resources that routinely expose server names, share paths, usernames, and department structures—goldmine context for attackers, but also for incident response and insider‑risk investigations.
For organizations operating under ITAR and EAR, this is where truly export‑controlled technical data actually lives—not in the folder name, but in the title blocks, annotations, and metadata attached to models and drawings.
Turning Solidworks Models into Actionable Security Signals
By parsing Solidworks 3D CAD files in place, inside your own cloud accounts or VPCs, Sentra can now treat them as first‑class citizens in your data security program—just like we do for DWG and other specialized formats.
That unlocks concrete use cases, such as:
- Finding export‑controlled or highly sensitive designs in cloud storage
Automatically surface Solidworks files whose metadata, annotations, or custom properties contain ITAR statements, ECCN codes, proprietary markings, or customer‑confidential labels—so you can focus remediation on the drawings and models that are actually regulated.
- Mapping who (and what) can access critical designs
Combine CAD‑aware classification with Sentra’s DSPM and DAG capabilities to answer:
Where are our most sensitive Solidworks assemblies stored, and which identities, service principals, and AI agents can currently reach them?
- Monitoring AI and collaboration workflows for IP exposure
Track when Solidworks files that contain regulated or high‑value IP are moved into AI data lakes, shared via collaboration platforms, or accessed by non‑human identities—so DDR policies can flag, quarantine, or route for review before they turn into public incidents.
- Building a defensible audit trail for CAD‑resident technical data
Maintain an inventory of Solidworks files that contain export‑control markings or IP‑critical content, tie each file to its exact storage location and access controls, and surface any out‑of‑policy placements—so when auditors ask “Where is your technical data?”, you can answer with data, not slideware.
Closing the Gap Between “Stored” and “Understood” for 3D CAD
As workloads like EDA, PLM, simulation, and AI‑assisted design move deeper into the cloud, the number of specialized formats in your environment explodes. Most tools still only truly understand emails, office documents, and a narrow slice of structured data.
The reality is simple: you cannot secure data you don’t understand. Understanding means being able to answer, at scale, not just “Where is this file?” but “What is inside this file, how sensitive is it, and how is AI amplifying its risk?”
For organizations whose crown‑jewel IP and export‑controlled technical data live in Solidworks 3D CAD, that’s the gap Sentra is now closing.
If you want to see what’s actually hiding inside your own Solidworks models and assemblies, the easiest next step is to run a focused assessment: pick a few representative buckets or repositories, let Sentra scan those CAD files in place, and review the inventory of regulated and high‑value designs that surfaces.
Chances are, once you’ve seen that map—and how it connects to your AI initiatives—you’ll never look at “just another CAD file” the same way again.
