You connect 12d Synergy and Asite with a CDE integration that moves civil drawings, models and metadata from the design team's 12d Synergy environment into the client's Asite workspace, and returns reviewed documents to 12d Synergy. CDE Sync™ links both platforms through dedicated accounts, maps 12d Synergy attributes to Asite attributes and logs every transfer.
Why civil designers deliver into Asite
12d Synergy is widely used by civil designers and surveyors who work in 12d Model, on roads, rail, drainage and land development. Asite is used by many owners, developers, contractors and public bodies to run a controlled document workspace, particularly in the UK and internationally. When a civil team on 12d Synergy works for a client on Asite, every design issue has to cross between them.
Without a connection, packages are exported from 12d Synergy, renamed to the client's numbering scheme, given Asite attributes and uploaded. Client comments come back by email or download. On a corridor project with frequent issues, the double handling takes days and creates opportunities to submit the wrong revision.
What carries across between 12d Synergy and Asite
CDE Sync™ moves files with their version history and maps 12d Synergy attributes to the attributes the client's Asite workspace requires. Document number, revision, status and discipline arrive in the form the client expects. The return path brings reviewed documents back into a nominated 12d Synergy folder with the outcome recorded. Every transfer is logged for audit.

How to connect 12d Synergy and Asite, step by step
Agree with the client which document types move to Asite and what returns.
Obtain the client's Asite workspace configuration, including mandatory attributes and numbering rules.
Request an Asite service account from the client's Asite administrator.
Arrange a 12d Synergy service account with access to the relevant jobs and folders.
Connect both platforms in the CDE Sync™ wizard and select folders on each side.
Map 12d Synergy attributes to Asite attributes and set the schedule.
Run a test issue, review it with the client's document controller, then switch on the full flow.
Agreeing what a civil submission contains
Civil submissions often include more than drawings. Reports, calculations, native models, string files and surfaces may all be part of a package. Clients differ on what they want in their Asite workspace. Some want PDFs only, some want natives as supporting files, and some want natives in a separate area for the builder. Agreeing this at the start keeps the client's workspace tidy and avoids large uploads nobody needs.
It also helps to agree how releases are signalled. Many design teams use a status or release folder in 12d Synergy to mark a package as issued. Pointing the sync at that signal means only released work reaches the client, while work in progress stays with the designers. Our guide to syncing ISO 19650 metadata between CDEs covers attribute mapping in more depth.
Once running, the connection needs little attention. Each scheduled run picks up newly released files, applies the mapping and records the result. Anything that fails a mandatory attribute in Asite is reported to the design team's document controller, who fixes it in 12d Synergy so the next run succeeds. Because CDE Sync™ is configured through a wizard, no developer time is needed when the client changes a picklist or adds an attribute partway through the project.
Security and data residency
CDE Sync™ streams files directly between 12d Synergy and Asite without storing them, encrypts data in transit and processes it in the Azure region you choose, which suits Australian, UK and European residency requirements. Utopia Digital holds SOC 2 Type II and Cyber Essentials. See the Security Trust Portal and the global data region map.
12d Synergy, Asite and the Utopiaverse™
A 12d Synergy to Asite connection is part of the Utopiaverse™, the connected record Utopia Digital builds across your platforms. CDE Sync™ keeps both aligned during delivery, CDE Backup™ keeps an independent copy in your own Azure, CDE Migrate™ handles moves onto or off either platform, and CDE Archive™ captures the record at completion. AI Insights searches design and client content together, with answers that cite the source files.
