Getting a new earthwork idea out of your head and onto the screen is the slow part. Until a concept actually exists, there is nothing for the team to look at, react to, or line up behind. That blank screen is the real hold-up, and it is exactly what Propeller CAD is built to remove.

Now in open beta, Propeller CAD lets you CAD with AI, right on your real survey data. Describe an earthwork idea in any language, or sketch it, and Propeller CAD shapes it into a workable concept on the ground you are actually working with. Roads, ramps, pads, and drainage, all inside the Propeller platform, from idea to concept in minutes.

Earthwork concepts, grounded in your site

Propeller CAD is built for the early, fast part of your workflow, the moment when you need something real on screen so the conversation can start. Describe a road, ramp, pad, or drainage concept in plain language, or sketch it, and watch it take shape as a 3D concept on your survey data, in the right coordinate system.

Because your first pass sits on what is actually on site, you are reacting to real ground from the very first minute, whether you work in civil construction, mining, or aggregates.

What you can do with Propeller CAD today

Once a concept is on the map, it lives alongside the rest of your site data, from volume calculations to site checks, so it is easy to sense-check against real conditions.

Describe it in any language: type or sketch your idea and watch it take shape as a 3D concept
See it on your real survey data: your first pass is grounded in what is actually on site
Iterate in the moment: adjust grades, dimensions, and tie-ins as things change, without starting over
Build in your own rules: upload your specs or design rules and Propeller CAD works to them
Save and revisit: keep concepts in your Propeller site list to come back to anytime
Export when you are ready: hand off as DXF or TTM into your normal design process

What teams are using it for

We are still learning what people do with Propeller CAD, and that is part of the point. So far, teams have reached for it to spin up quick concept designs, shape temporary works before detailed design begins, run fast feasibility studies by weighing a couple of options side by side, and communicate a change on site by turning an idea into something visual the whole crew can align around.

It is proving just as useful for keeping progress tracking honest against a plan as it is for helping survey and engineering teams get a head start, and for transportation projects where staging and access change by the week.

Where Propeller CAD fits

Propeller CAD gives you a concept to work from. Like any design tool, the quality of what you create depends on your inputs and your judgment. It produces a concept, not a final engineered deliverable, and engineer sign-off stays with a qualified professional. Whether your project needs that sign-off is your call.

How it works

Describe or sketch your idea: a haul road, a pad, or a ramp, put it into words in any language or sketch it, and Propeller CAD generates a 3D concept on your real survey data
Refine and adjust: tweak grades, dimensions, and tie-ins interactively until the concept fits your site
Export and share: when you are happy, export as DXF or TTM to take into your next steps, and keep the field and office working from the same picture

Built into the platform you already use

Because Propeller CAD lives inside Propeller, your concepts sit next to your survey processing, your daily reporting, and everything else your team already works from. There is no extra software to install and no separate file to chase down.
