Let everyone see the project before it's built

We rebuild your design from the CAD files you already have as a photorealistic, geometrically accurate Unreal Engine model, then stream it from cloud GPUs to any browser. No CAD seat, no graphics card, nothing to install.

Request a demo Compare existing and proposed

Built from DGN, DWG, OpenRoads, InfraWorks, Civil 3D or SketchUp files, with the survey, terrain and imagery you already hold.

From RDV Systems, trusted by 24 state DOTs since 2005.

An intersection design, rendered as a 3D model for a public meeting

See the design where it will stand

The Frank J. Wood Bridge near Brunswick, Maine, modeled as it stood and as a replacement was proposed, from one viewpoint in one model. Drag across the picture to compare.

How existing conditions are modeled

The existing steel truss bridge, modeled with the riverbanks and mill buildings around it

The proposed replacement bridge in the same view, with curved walls and planting where it meets the bank

From design files to a live model, in four steps

You send the files you already have. Everything after that is ours.

Send the design
DGN, DWG, OpenRoads, InfraWorks, Civil 3D or SketchUp, with the survey, terrain and aerial imagery you already hold. No re-drawing, no special export.
We rebuild it in 3D
The engineered geometry becomes real geometry: pavement and markings, structures, barriers, signs, lighting, terrain and planting, at the level of detail the project calls for.
Unreal Engine lights it
Real-time lighting, materials, sky and weather, moving traffic and people. The same model at 8am in June and at dusk in December, because both are questions people ask.
The cloud runs it
An invited viewer signs in and a GPU session starts for them, streaming the model to their browser. Nothing to install, no workstation, no graphics card at the far end.

A model you drive, not a video you watch

A rendering shows one viewpoint that someone chose. A real-time model answers the question being asked in the room, while it is being asked.

Drive the alignment at the posted speed, walk the sidewalk, fly the corridor
Change the time of day, the season and the weather
Turn layers on and off: proposed against existing, or one construction phase
Saved viewpoints, so a presenter jumps straight to the four views that matter
A guided tour the people you invite follow at their own pace, in their own time

One model, every deliverable the project needs

The model is the source, so the video, the boards and the link never show three different designs. When the design changes, it is updated in place.

A photorealistic still of a bridge under construction, with traffic on the open lanes — A construction stage, rendered from the model the video comes from.

Drive-throughs and flyoversHD video along any route in the model, at road level or from the air.
Phasing sequencesEach construction phase in order: detours, closures and temporary alignments.
StillsFor display boards, slide decks and press, from the same model as the video.

What DOTs and firms use it for

Anywhere a decision waits on people seeing the same thing.

Public hearings
Presented live in the room or in a headset at the back of it, residents see the road that will be built from their own street instead of reading a plan sheet. Objections come back about the design, not about what people imagine it to be.
Design review
Reviewers drive the alignment and look at the conflict everyone is arguing about, from the driver's seat, in the meeting.
Alternatives
Switch between alternatives in the same session and on the same terrain, so a preference is a choice between two things people have actually seen.
Construction staging
Walk each phase before the first cone goes out: detours, closures, temporary alignments and the sequence the public will live through.
Funding and partners
A model a commission, a city council or a funding partner can navigate themselves does more than a rendering does.
Safety, on the same model
The model feeds Road Safety Audit 3D, so the design can be audited for sight distance while it is still a design.

What it does to a public meeting

In the words of the people who ran the meetings.

All testimonials

80%less hostility in the room once the RDV model opened
“As soon as we opened the RDV model the level of hostility in the room dropped by 80%.”

“This was such a great tool to let people see an actual representation of what the end product was going to look like from any viewpoint that they wanted. We also brought it into a VR headset for people to actually experience it at the open house in virtual reality, as well as having the Navigator projected on the screen while playing the animation, and stopping to jump to different views to answer specific questions.”

“The RDV models were the star of the show and made it possible for our team to share an extremely complex proposal with the public in a way that was easily understood.”
