The toolkit

One tool for every manual job.

Each tool does a job you used to do by hand, dozens of times a drawing. Hover to watch it work, drag inside the catchment and 3D panels to play with them.

Grading analysis
7%

Slope Check

7% PASS

Two clicks between any levels. Pass or fail as a percentage, against your own surface standards.

+50.20 +50.05 +49.90 +49.75

Level Maker

AUTO FFL

Set a start, a slope and a direction, then click along the path. Levels place themselves.

Catchment

FLOW → LOW

Pick your levels and read drainage direction. Drag inside the panel, the flow re-aims at the low point.

Topography New
+1.0 +2.0 +3.0

Berm & Mound

PEAK +3.00

Draw a boundary and contours fill it with levels. Simple, multi, dual-peak or ridge, with presets.

+52.0 +50.0

Grade & Slope

+52.0 / +50.0

A different level on every edge? It grades the surface between high and low sides, any shape.

+51.37

Spot Level

+51.37

Click anywhere on a graded surface and read the interpolated elevation, dropped on as an annotation.

AA'

Cross Section

SECTION A–A'

Draw a line across the terrain and get a clean, dimensioned section profile in one click.

3D & visualisation Major
The part that turns flat drawings into something you can see. Generate a real 3D surface from your grade, push it around in the viewer.

3D Surface Generation

MESH

Turn your graded levels, berms and contours into a true 3D surface, generated straight from the drawing.

PUSH / PULL

Drag the slider and the whole surface lifts and settles in real time - the same live control you get inside the plugin.

Your own standards
Five built-in surface types, plus unlimited custom thresholds, customised to match your office template.
Clear pass or fail
Every slope checked against your thresholds and marked right on the drawing.
Installs in seconds

Why GradingMaster exists

Every landscape architect knows the routine. Levels on a drawing that need checking. Slopes to calculate, two points at a time. Berms to shape, contour by contour. A graded surface with a different level on every edge. Pull out the calculator, subtract, divide, check the threshold, write it down, redraw when it looks wrong. Next one. Fifty times. A hundred times. Every drawing, every project.

None of it is hard. It is just endless. Offsetting polylines inward to fake a mound. Guessing the levels between two edges. Checking your 80th slope at the end of a long day. That is where the one that matters slips through, the one that shows up on site three months later as a puddle where there should not be one.

GradingMaster was built to end that. Click two annotations and see the slope. Draw a boundary and watch the contours fill it. Click anywhere on a surface and read the level - the answer is there before you would have finished the first calculation by hand.

The grading and terrain work that was always tedious - the simple thing done by hand a hundred times - finally just works.

Built-in surface types

The grading on a single plan

less time with GradingMaster

Based on a typical mid-size grading plan: roughly 130 slope checks, spot levels and placed levels, plus a few berms and sections. By hand that is three to four hours of calculating and redrawing. GradingMaster clears it in minutes.
