From field survey to topographic plan, volumes and cross sections — accurate, in GGRS87 (ΕΓΣΑ87), with no Internet connection required.
One tool, from importing your points to the final report.
Delaunay triangulation with breaklines, outer boundaries, holes and a maximum edge length. Multiple surfaces in the same project.
Major and minor contours, smoothing and export to DXF or PDF. Elevation labels where you want them: on major contours, every N-th contour, every 5 m of elevation or given elevations, as often as you set.
Cut, fill and net volume between two surfaces or between a surface and an elevation, with a cut/fill map.
With one option, the points of a spot grid (e.g. every 20 m) become a surface with triangles and contours only inside the perimeter, over the drone survey or the orthophoto, updated with the grid.
The centroid of the cut volume and of the fill volume, with the distance between them for hauling, in polygon earthworks and volume comparisons: in the window, the Properties, the PDF / Excel reports and, if you wish, the drawing.
The 3D polylines of a DXF / DWG (roads, networks, cables many km long) become 3D lines, with no surface to build. One click on a line gives its weighted slope, and all the routes together come in one table with totals, Excel and CSV.
Points every so many metres inside a perimeter, with their elevations on the survey or the orthophoto (e.g. “48.62 m”) and, optionally, the Δz to the design. Numbered for setting out and checking, as CSV, TXT (PNEZD), DXF / DWG, Excel and a PDF at scale.
Machines and trucks come off the drone survey: found automatically, with a list to check, or you draw their outlines. The ground under them is made from the ground around, on point clouds, RGB clouds and DEM / DSM.
Encircle debris or a deposit inside an excavation and the ground comes down to the ground around it. Into a copy, the comparison gives the volume of the material at once.
Light, Dark (Windows 11), CivilShop or as Windows. The dark theme covers the ribbon, tree, tables, profile, cross sections and the 3D view. Reports and exported images always keep a white background.
Draw sub-areas with a grade on each side as you draw. You get at once the design surface with side slopes and its cut / fill against the ground, with volumes per area.
Where the water runs and where it stays, with the depth and volume of each pool. A drainage basin from one click at the outlet: area, longest flow path, time of concentration and peak flow.
Inside an outline: the least earthworks for a largest grade (e.g. 5%), with drainage where you draw water paths and outlets, points of given elevation, limits and balance.
Draw the outline, set the side slopes and change the depth with a slider — volumes update instantly.
Cross sections at any interval you like, cut/fill areas and volumes by the average end area method.
Add or move points, change elevations, flatten areas, raise or lower ground — with full Undo/Redo.
In a LiDAR / drone cloud: from a rough line and the typical section, crest, toe, edges and ditches become breaklines, and the ground is cleared of vehicles and vegetation without losing the edges.
GeoTIFF / BigTIFF, ESRI ASCII Grid, SRTM and BIL / FLT, transformed into the project’s system (e.g. WGS 84 → GGRS87), with only the project area taken from large tiles.
Point groups, breaklines and boundaries of every surface with check boxes, alignment parts by double-click, ⚠ whatever is out of date, an item list and selection by clicking in the drawing.
After − before differences on a grid at any spacing (e.g. every 10 m) over the cut / fill map, in the PDF / Excel report and in DXF / DWG for AutoCAD.
A drone cloud as a gridded surface at the sampling you type and in its real colours, with no orthophoto; shaded, wireframe or points with one click.
Parallel cross sections every few metres inside a boundary, grid nodes with Δh, areas and volumes by the average end area method — checked against the exact TIN volume. Ideal for dredging, yards and excavations. PDF report, Excel and DXF/DWG.
Final against natural ground over the whole uncovered plot area: ±1.50 m (steep plots >20 %: −2.00 / +1.50 m), 0.80 m permit threshold, buildings and ramps excluded, a class map and the points beyond the limits. All limits are editable.
Sections at 1:100 / 1:200 / 1:500 with natural and final ground, the allowed range, buildings and plot boundaries — in PDF and DXF/DWG, together with a PDF / Excel report.
Pick a plot or pad (zone, closed line, DXF/DWG or coordinates) and get cut / fill instantly for a level or inclined plane, with balance, side slopes and a live slider.
Topsoil stripping, swell / compaction factors, surplus or borrow with truck trips, and an excavation-waste table (ΣΔΑ – construction-waste management plan, EWC 17 05 04) in the reports.
Depth lines below the long profile (e.g. 1.20 / 1.30 m), depth marks at any interval, trench volume, a setting-out table in Excel/CSV and a 3D line in DXF/DWG.
The outlines already in your drawing become zones in one click — named after the drawing's texts — and the volume per zone is available immediately.
Σ rises / route length from an axis, a line or a points file, with the classic table (No., X, Y, Z, Station, ΔX, ΔH, Grade, ΔHv) in Excel.
Graded pads with side slopes that find the elevation where cut = fill on their own. Feature lines with elevations and grades.
Open and save DWG without AutoCAD. Automatic linework from survey point codes (curbs, centerlines, buildings).
Arcs and clothoids, a grade line with vertical curves you drag with the mouse, typical section, road surface and mass-haul (Bruckner) diagram.
Ground filter for unclassified point clouds, and orthophotos (GeoTIFF / world file) draped over the terrain.
3D distances and areas, stockpile/pit volumes, volumes per zone, a point table and contour editing.
Plans and cross sections on A4–A0 sheets with title frame, legend and your logo, ready to print.
The two surfaces are overlaid triangle by triangle and the volume is integrated exactly — not on a grid.
Side slopes are intersected geometrically with the natural ground, so the final outline is the real one — not a fixed horizontal offset.
Draw an axis and get a long profile and cross sections in seconds.

Not for your work. The license is checked whenever a connection is available; without Internet the program keeps working normally for 7 days.
Yes, fully — along with UTM, WGS84 and ETRS89. Coordinates are kept at full precision and calculations are performed without rounding.
No. EARTHWORKS → “Zones from DXF / DWG”: choose the layer and every closed outline becomes a zone, named after the text found inside it. Volumes per zone appear immediately and are carried into the reports.
Yes. EARTHWORKS → “Polygon earthworks”: click the zone or closed outline (or take it from DXF/DWG) and set an elevation, an inclined plane or cut/fill balance. Cut, fill, topsoil, truck trips and the ΣΔΑ table (construction-waste management plan) are produced instantly in PDF / Excel.
SECTIONS → Route → “Import routes…”: the 3D polylines of the DXF / DWG become 3D lines, with no surface, named and coloured per layer. One click on a line shows its weighted slope (Σ rises / horizontal length) in the Properties, and the “Weighted slope of all lines” table gives every route together, with sorting, totals and export to Excel / CSV.
TERRAIN → “Remove objects”: the program finds them by itself and shows you a list to check, or you draw the outlines yourself. The ground under them is made from the ground around, on point clouds, RGB clouds and DEM / DSM, and the volumes no longer count them. For debris or a pile inside an excavation there is “Replace terrain”.
Yes. TERRAIN → “Spot grid”: give a perimeter and a spacing, and every point gets a number and an elevation, on the surface or on the orthophoto. With a second surface (e.g. the design) it also gets its Δz. The points are exported as CSV, TXT (PNEZD) for setting out, DXF / DWG, Excel and a PDF with a plan at scale.
TERRAIN → “Follow road / channel”: draw a rough line along it, set the typical section on the first section (crest, ditch, edges, toe) and the program follows it by itself. It gives the coded breaklines and separates the ground from vehicles and vegetation in the corridor, keeping the edges.
Yes. HOME → Import → “DEM (GeoTIFF, ASC, HGT, BIL)”: GeoTIFF and BigTIFF, ESRI ASCII Grid, SRTM tiles (.hgt) and ESRI BIL / FLT. The coordinate system is read from the file or its .prj and the points are transformed into the project’s system (e.g. WGS 84 → GGRS87). From large DEMs you keep only the project area or one cell in n.
In the Project Explorer. The Project Explorer (since version 1.6.3) shows every object with icons, the definition of every surface (point groups, breaklines, boundaries, edits with check boxes), the parts of every alignment, marks with ⚠ whatever is out of date and updates it with one click, opens an item list per collection and selects objects by clicking in the drawing.
Yes. TERRAIN → “Merge surfaces”: choose the surfaces in order of priority and the program builds a new surface. In the common area it can keep only the points of the first one, align the heights (e.g. two drone flights) and thin the points on a grid. The original surfaces stay untouched.
Yes. EARTHWORKS → “Section grid”: pick or draw the boundary, set a design level (e.g. −5.00 m) or a design surface and the distances of the sections and nodes. The baseline follows the long side of the boundary automatically. You get the areas of every section, volumes by the average end area method, a check against the exact TIN volume, nodes with Δh and a full PDF / Excel / DXF report.
Yes. EARTHWORKS → “Building-code check”: choose the plot, the natural and the final ground and the buildings to exclude. The program compares the two TINs exactly at every point of the uncovered area (±1.50 m, steep plots −2.00 / +1.50 m, 0.80 m permit threshold) and produces a report, a class map and permit sections at scale. The limits and the way the plot slope is computed are editable; the check is an aid and the final judgement is the design engineer’s.
Yes. SECTIONS → “Weighted slope”: Σ rises / length, from an axis on the ground (every N m), from a line or from a points file, with export of the table to Excel. Since version 1.6.2 a click on a 3D polyline you imported (or on a breakline / feature line) is enough: X, Y, Z are taken directly, with no ASCII file.
Yes. EARTHWORKS → “Δz labels on a grid…”: give the node spacing and the after − before differences (+ fill, − cut) are written on the map, on the plan of the PDF report, in an Excel sheet and in the “Δz map DXF / DWG” for AutoCAD.
Yes. When importing a LAS / LAZ tick “Gridded surface”, type the sampling (e.g. 0.50 m) and choose the cell elevation (lowest, mean or highest point). The surface is shown in the RGB colours of the points, shaded, as wireframe or as points, and the colours are saved in the project.
Yes. Since version 1.2, DWG files (AutoCAD R14 to 2018+) are read directly, without AutoCAD or any other program, and all CAD exports can also be saved as DWG.
Millions of points, with ground-class filtering and grid thinning on import. A 300,000-point TIN is built in about one second.
Yes. Use “File → License → Deactivate” to release the license, then activate it on the new computer.
Yes, a detailed, fully illustrated manual: English (HTML) · PDF · Greek (HTML) · PDF. It is also installed with the program (press F1).
Yes. The interface is available in English and Greek, and you can switch between them with one click. PDF/Excel reports are produced in the language you choose.
