Create a Project

When using the Civil 3D plugin, your project is created automatically the first time you run 2D Checks on a drawing.

Prepare your linework in Civil 3D

Before submitting a grading job, validate and clean your geometry inside Civil 3D.

  1. Open your drawing in Civil 3D.
  2. Run the 2DLINEWORK command (or click 2D Checks in the ribbon) and work through the Layer Review step of the wizard. Assign each layer to the correct geometry type: lot lines, curbs, road centerlines, edge of pavement, edge of swale, or right-of-way.
  3. Continue through the wizard to validate and clean your 2D geometry.
  4. Review the results in the Grading Prep Review panel and fix any issues (overlapping lines, open endpoints, short segments).
  5. Run the 3DLINEWORK command (or click 3D Checks in the ribbon) to generate 3D feature lines with elevations assigned to each vertex.
  6. Resolve any 3D-specific errors before proceeding.

Get Grading

  1. Run the LOTZONEGRADING command or click Lot & Zones Grading in the DRTWRK Tools ribbon.
  2. Your file is uploaded to drtwrk.
  3. drtwrk automatically recognizes your linework into lots, zones, and areas.
  4. Apply a preset.
  5. Submit.
  6. Manual edit if needed.
  7. Export to CAD.
