Welcome to drtwrk
drtwrk is an automated lot grading platform built for civil engineers. It connects directly to Autodesk Civil 3D and automates the most time-consuming parts of grading design.
Who is it for?
drtwrk is designed for:
- Civil engineers and land developers running residential or commercial grading projects
- CAD technicians submitting lot grading at scale
- Project managers who need visibility into grading job status
Whether you're processing a single residential lot or an entire subdivision, drtwrk automates the repetitive, error-prone parts of grading so you can focus on design decisions.
Key capabilities
- Process 2D and 3D linework — validate and clean lot lines, curbs, road centerlines, edge of pavement, edge of swale, and right-of-way geometry directly inside Civil 3D
- Submit grading jobs — send lot, block, and zone grading work to the cloud grading engine with a single command
- Review results in the web dashboard — monitor job progress, inspect grading output in an interactive 3D viewer, and make manual elevation edits without leaving the browser
- Use presets — define and reuse standardized grading parameters across projects to enforce design standards and reduce setup time
- Native Civil 3D integration — supporting Civil 3D 2023, 2024, 2025, 2026, and 2027
How it works
From your perspective as a user, the drtwrk workflow moves through these layers:
