CAD Data Management Software
Every Deliverable Issued with Confidence.
The leading CAD data management solution purpose-built for civil and infrastructure designers who need to collaborate fast, protect their work, and deliver clean, traceable drawing sets.
The Hidden Cost of CAD Chaos
Most design teams in the US are running on a patchwork of shared drives, personal folders, and manual processes stitched together with good intentions and tribal knowledge. It works, until it doesn’t. A broken Xref. An outdated sheet issued to a contractor. A title block update that takes two hours across 80 drawings.
The result? Three critical risks that erode productivity and put deliverables at risk:
Generic cloud storage and shared drives were built for individual files, not the interconnected, reference-heavy drawing sets that civil and infrastructure designers produce every day. When collaboration scales up, these tools break down.

The Cost of Waiting
CAD complexity isn’t decreasing. Drawing sets are getting larger, teams are increasingly distributed, and clients are demanding greater traceability while shared drives and email-based workflows stay stuck in the past.
Design datasets are getting bigger and more interconnected.
Point clouds, geospatial references, 3D models, and sheet sets with hundreds of Xref dependencies push shared drives to their limits. Slow transfers, corrupt files, and broken references aren't just frustrating, they're billable time lost.
Remote and distributed teams are the new normal.
Designers working across multiple offices, from home, or on site need reliable, fast access to the same controlled drawing set. Without proper infrastructure, remote work means version drift, missed updates, and the constant anxiety of not knowing if you're working on the right file.
Clients and contractors are demanding better traceability.
On US infrastructure projects, particularly those involving public agencies, federal funding, or quality management obligations, "what version went to construction?" is a question you need to be able to answer precisely. An email thread isn't an answer. A complete transmittal record is.
The Competitive Advantage
Design firms that invest in proper data management spend less time on admin and more time on billable design work. When clients ask how you manage drawing quality and version control across a large team, you have a system-backed answer, not a policy document that depends on everyone doing the right thing.
12d Synergy gives your design team the tools to do what they’re best at — designing — while the system handles the governance, version control, and record-keeping in the background.
Every day without proper CAD data management is a day you’re exposed to:
What Civil Design Leaders Are Saying
"12d Synergy has allowed us to streamline our processes and work more efficiently, ensuring all staff always have the latest data on hand wherever they are. We no longer have issues of 'where is the document, where is the email, and what is the latest issue?'"
"The Bulk File Attribute Editor is probably my favourite feature. It enables extremely fast title block changes to all attributed blocks without the need to even open AutoCAD. It makes our life a lot easier and smoother, particularly working across two offices and different teams."

FAQ – Common Questions from Civil Design Teams
Yes. 12d Synergy has native plugins for AutoCAD, Civil 3D, and BricsCAD that let you check drawings in and out, manage Xrefs, update attributes, and track versions without leaving your CAD environment. It also supports MicroStation, 12d Model, and most other tools used in civil and infrastructure design.
No. 12d Synergy is software-agnostic and works alongside whatever platforms your clients or project partners require. Your team manages drawing production and version control in 12d Synergy, and data can be shared with other platforms without disruption or duplication.
12d Synergy maps the relationships between your DWG files automatically. When you move or rename a file, references update without breaking. You can visualize Xref trees, roll back reference versions, and manage nested references — all without touching a lisp routine or manual rebind.
12d Synergy is configured to match how you already work. Your existing folder structures, naming conventions, and drafting standards are built into job templates, so every new project inherits your firm's standards automatically, without forcing anyone to change their habits.
Local caching means designers work at full speed from their own machine, with files synced securely to the central server. Only changed files are transferred, not entire drawing sets, so remote access is fast even on standard internet connections. No VPN required.
Most design teams are productive within 2–4 weeks. The setup process is straightforward, and 12d Synergy's support team who understand AEC workflows, not just IT, guide you through configuration and onboarding from day one.
