Long section from Excel — preview and elevation checks
Paste a table, correct your data and preview a utility profile without signing up. Continue in Altivo with your points and elevations intact.
Four columns in this order: name, distance from start [m], ground level [m], utility level [m]. Start at 0. Tabs or semicolons; comma-separated CSV requires decimal points.
Distances are horizontal and measured from the start. The preview creates a schematic route without survey coordinates. Enter invert levels for gravity sewers and centreline levels for other networks. Warnings do not change your data or replace hydraulic calculations and standards checks.
Calculations run in your browser. Clicking Continue keeps a draft on this device for 7 days. Save it to your account after signing in. Avoid private browsing if you want to return later.
How do I prepare the table?
Select the data format, copy the matching spreadsheet columns and load them above. Missing values and distances in the wrong order block the preview. Inspect geometry warnings on the drawing and correct values directly in the table.
From preview to a complete project
After signing in, save the draft to your chosen organisation. In the editor you can select materials, add branches, crossings and objects, then export according to your account access.
Example utility projectsFrequently asked questions
What columns does the spreadsheet need for a long section?
In "Name · distance · ground · utility level" mode the table needs exactly four columns in this order: point name, distance from the start of the route in metres (the first row must be 0), ground level in metres, and utility level in metres — invert level for a gravity sewer, centreline level for every other network. Copy those four columns from your spreadsheet and paste them in, tab- or semicolon-separated.
I only have X/Y coordinates, no elevations — can I still use it?
Yes. Switch to "X · Y — no elevations" for a plan-only route preview, or "X · Y · ground level" to also get a working long section with the utility centreline set 1.5 m below ground by default (adjust the depth later in the editor). Point names (P1, P2…) and distances are generated automatically from the coordinates.
What delimiters and number formats does it accept?
Tabs or semicolons between columns. Numbers accept a comma or a point as the decimal separator — if you're pasting comma-delimited CSV, use decimal points, since the comma is already the column separator. Tick "First row contains headings" if your paste includes a header row.
How many points can I paste, and which network types are supported?
Up to 200 points and 100,000 characters per table, with a 100 km limit on the total route length. All seven Altivo network kinds are available — water, gravity sewer, pressure sewer, gas, power cable, telecommunications and district heating — and the preview follows the geometry rules for whichever one you pick.
Does my data get uploaded anywhere?
No — pasting, validation and drawing all run in your browser. Clicking "Continue project in Altivo" only saves the draft locally on this device for 7 days and takes you to registration; it is added to your account and organisation only once you sign in.
Can I export the long section to DXF straight from this page?
Not from the preview itself — continuing takes you into the Altivo editor (sign up, 14 days free, no card), where you set the real pipe material and diameter, add branches, crossings and objects, then export to DXF or XLSX according to your account's access. The trial applies a daily DXF export quota.
