Finished Lot Grades in Seconds directly inside Civil 3D™
Turn hours of manual grading work into seconds, and make changes without starting over.
Join engineers testing drtwrk on real projects.
Five steps, inside your own drawing
Constraints in, graded surfaces out, and back into Civil 3D without breaking the dependency chain.
Import alignments and parcels, then clean 2D boundaries before grading.
Accuracy, speed, and a grade you can trust
Geometry checks, live grading, multi-solution comparison, manual editing, and finished lot grade export to CAD
2D checks
We verify the 2D linework is closed before grading, no overhangs, underhangs, overlaps, or geometry errors.
3D Checks / Feature Line Creation
We create every feature line within your lot, in a minute, on a thousand home sites.
Set up constraints & presets
Slope, setback, and drainage presets carry forward from Civil 3D. Then the grade runs against those constraints from the first pass.
Live grading
Constraints and checks update the grade as you change inputs. You see the result immediately, not after a full redo.
Multiple solutions
Generate more than one valid grade for the same lot. Then compare scenarios side by side before you commit.
Manual edits
Refine the grade inline after generation. You keep the parametric result instead of throwing it away.
Export to CAD
Push approved feature lines and surfaces back into Civil 3D. They land in your drawing without breaking the dependency chain.
Built by civil engineers
Accuracy, speed, and confidence on finished lot grades, not speculative layouts.
Time vs. manual
Hours of hand grading become seconds. Change one constraint and the grade updates everywhere it applies. No starting over. Grade every feature line in a lot, in a minute, at thousand-home-site scale.
Not another layout tool
Finished lot grades for Civil 3D. Feature lines and surfaces that land in your drawing. Built for your existing Civil 3D workflow. Not speculative massing or a layout exercise. Not a Civil 3D replacement.
Cost of Change
Design changes that once meant hours of rework now cost almost nothing. Shift a setback or adjust a constraint. The grade rebuilds in place. Less risk per iteration means you explore options instead of the first workable answer.
