Solidworks PDM alternatives
In this guide, we explain why most CAD workflows fail, explore the best alternatives, from user-friendly tools like Anchorpoint to the classic power of free SVN.

If you've ever had to deal with the nightmare of managing huge engineering files and naming them things like "Assembly_Final_v3_FINAL.step", then you'll already be familiar with the pain involved. This is precisely the area in which Product Data Management (PDM) software can be a real lifesaver.
Think of a PDM as the ultimate source of truth for your physical product designs. It can handle your large CAD files, bills of materials (BOMs) and complex revision histories.
Now, if you're a software engineer reading this, you might be thinking, "Wait a minute, isn't that just Git with GitHub?"
Yes and no! PDM tools have a lot in common with standard version control apps used in coding. Both offer version history, branching and cloud syncing to enable team collaboration. However, PDMs are specifically designed to handle large 3D binary files. They offer essential hardware-centric features such as file locking, which prevents two mechanical engineers from accidentally overwriting the same CAD model at the same time, as well as native integrations directly inside tools such as SolidWorks or AutoCAD.
Finding the right PDM can feel like wandering through a maze of corporate jargon. Let's break down our favorite options out there right now.

Anchorpoint allows your software engineers to continue using the Git workflows they are familiar with, such as branches, pull requests, and CLI magic. Meanwhile, artists and designers receive a user-friendly desktop application with features like file locking, visual diffs for 3D scenes, and cloud backup. The “hardware” folks aren't stuck in email hell swapping ZIP files anymore, and the engineers don't have to learn an esoteric check-in ritual. It's a genuine "two worlds merge" moment.

If SolidWorks is your bread and butter, PDM is an obvious choice. It’s deeply integrated into the CAD environment. You can check files in and out from the task pane, track references, manage revisions, and automate PDF creation. SolidWorks PDM Standard comes with SolidWorks Professional and Premium licenses, so many teams already have it.

Vault is a classic PDM that integrates directly with Inventor, AutoCAD, Revit, and more. If your team relies on Autodesk products, Vault will feel like a natural extension. It manages CAD file relationships, automatically creates PDFs and STEP files when you check in files, and enforces revision schemes without you having to do anything.

OpenBOM takes a different approach. It focuses less on heavy 3D file check-in and check-out and more on managing bills of materials, change orders, and product data across your supply chain. However, it does include revision control for CAD files and a very generous free tier for up to ten users. It's the "popular free" option you've been looking for!.

Bild is a newer, cloud-native PDM that focuses on making version control and BOM management as simple for mechanical engineers as Google Docs is for writers. It integrates directly with SolidWorks, Onshape, and Fusion 360, offering file locking, revision history, and visual comparisons, all inside a clean web dashboard.

Product data management (PDM) is a system designed to manage design files, CAD assemblies, bills of materials, and revisions, typically for hardware teams. Although version control tools like Git are built for code, PDM offers critical features for managing binary assets, such as file locking to prevent overwriting, visual diffs for 3D models, bill of materials (BOM) management, and CAD-aware integrations. Modern hybrid PDM tools like Anchorpoint use Git behind the scenes but present it in a way that mechanical engineers and artists find intuitive.
Anchorpoint is built on top of Git. This enables software and hardware engineers to collaborate within the same ecosystem and provides a visual interface optimized for 3D assets.
Unlike code or text documents, 3D CAD models are large binary files that cannot easily be auto-merged. File locking prevents chaos by ensuring that two engineers don't open, edit, and overwrite the same file at the same time.
Because Anchorpoint runs on Git, engineers have to get used to a local-to-remote Git workflow. This means you have to make sure your local repository is fully updated with your team's latest changes before you can push your own work, which is a bit different from traditional PDM check-ins.
