Long sections for every utility network Get the plan view and long section as a DXF — in minutes, not hours.
Altivo is online long section & profile software — no install and no CAD license. Water mains, gravity and pressure sewers, gas, district heating, plus electric and telecom cables — in one project, on one drawing. Paste coordinates, generate the profile, and export a clean DXF ready for CAD or a 3D IFC model for BIM.
14 days free, no payment card required.

Three steps from survey to DXF and BIM
No install, no dongle, no waiting for it to unfreeze.
Paste coordinates
We accept CSV, TXT, and data copied from CAD or Excel. Separator detected automatically. X, Y, Z or X, Y with a default ground level.
Design the network
Add nodes and segments, set slopes, depths and invert levels — all with a live preview. Gravity sewer with manholes and drops, water mains, gas lines or cable runs — in one project.
Download DXF, 3D or IFC
DXF of the profile and plan: dual scale (separate H and V), tidy layers — opens in AutoCAD, ZWCAD or BricsCAD. Need 3D? Export a 3D model (DXF) or a georeferenced IFC for Revit and BIM tools in one click.
See how it works in practice
Plan view and long section in one tool
Many networks on a single drawing. Main run, branches, crossings — visible immediately in both the plan and the profile.

Plan view — all networks in industry colours, crossings highlighted automatically.

Profile view — ground line, pipe axis, a 10-row table with elevations, slopes and stationing.
A DXF ready for further CAD work
Open the file and keep layers, text and route range under control from the start.
Layers
P_WATER_ROUTE
Separate layers for networks, labels, elevations, crossings and tables.
Text
MText
Labels stay editable after opening the file in CAD.
Range
0+120 - 0+460
Export the whole profile or only the selected route section.
Offset
0,0
Large coordinates are shifted closer to zero for more stable work.
Dual scale
Separate horizontal and vertical (e.g. 1:500 / 1:100), generated automatically from the route range. You pick the starting and ending stationing before export.
Editable MText
Labels are not exploded into line segments — in CAD you change the text in one click. No retyping, no OCR-ing your own drawing.
Layers prefixed by industry
P_WATER_ROUTE, P_SEWER_ELEVATIONS, P_GAS_LABELS. Every network and every drawing type has its own layer — you control visibility and colour independently.
Coordinates normalised to zero
Large coordinates can reduce precision in some CAD tools. The export automatically subtracts an offset computed from min(X), min(Y) — the DXF opens near 0,0.
3D export: IFC & 3D DXF
You can also download the same project as a 3D model. The IFC file carries EPSG georeferencing and loads into Revit via “Link IFC” and other BIM tools, while the 3D DXF — pipe axes and simplified solids sized by diameter — works as an underlay in AutoCAD or Civil 3D.
Seven industries, sensible defaults
Create a new network and you already have the right parameters. Every default can be overridden per network, per segment, per point.
