What's new

Free drawing in plan view

Place successive route points without opening a form. Snap to the DXF underlay, extend routes and draw one branch after another. Enter commits the sketch; undo reverses the whole operation.

• Constrain drawing to the axes or 45° increments, enter a segment length and angle, or align a point with existing nodes. Guides also help you draw the next segment parallel or perpendicular to the previous one.

CSV to DXF in English and German, plus direct Gauss-Krüger ↔ UTM

A new free tool, in English and German, turns a point list from Excel or CSV into a DXF with point-ID labels and optional elevations. The German coordinate converter now also converts directly between Gauss-Krüger (DHDN) and ETRS89/UTM. Points from both tools open in the Excel long-section preview in the same language, without signing up.

• Explicit column mapping (ID, easting, northing, elevation), decimal point or comma, point IDs with leading zeros kept as they are; metres only — feet are not converted.
• Faulty rows are reported instead of skipped; coordinates and elevations are never transformed behind your back.
• Gauss-Krüger ↔ UTM uses a Helmert approximation — fine for planning, not for cadastral work.

CAD routes, compact branch tables and separate drainage defaults

Import open DXF polylines as a main route with branches. Hide repeated branch table headings, save separate foul and storm sewer defaults, and reuse levels from an existing building.

• Pipe centrelines and outlines use separate DXF layers.
• Branch junctions reuse existing nodes even with higher-precision coordinates.
• Import creates a new network after checking connections; closed polylines and arcs are skipped.

Raised covers and default invert depth

Set manhole or chamber covers above existing or proposed ground. For networks other than gravity sewers, choose a default depth to the centreline or invert, including a separate setting for each branch.

Connect with other designers on the forum

The Polish-language Deska Kreślarska forum is now linked from the Altivo menu and footer. It opens in a new tab so you can ask a question without leaving your project.

Adjust plan labels and add detectable tape

The DXF export dialog now lets you set the printed plan annotation text height in millimetres, including level annotations. Every network supports independent warning and detectable tapes, each with its own height, range and DXF layer.

Point and manhole elevations in the DXF plan

Export the plan with ground levels, sewer invert or pipe centreline levels, and manhole floor levels, without copying values into CAD by hand. Labels are editable on a separate layer. You can turn them off in the export dialog.

Safer saving and recovery of your work

The editor keeps a draft in your browser so you can restore unsaved edits after reloading. When versions conflict, save your work as a separate project or download JSON. Renaming projects and opening links no longer block subsequent saves.

Underground hydrant and draw-off point in the object library

Two new objects for water mains and irrigation: an underground hydrant and a draw-off point (a buried box with a quick coupling). They draw the way they look on site — nothing above ground, a street box set flush with the surface and a riser off the main. No more redrawing them in CAD after export.

• Underground hydrant: street box with the valve symbol, DN80 by default
• Draw-off point: the same box with a 1" quick coupling — for irrigation designs
• The riser follows the hydrant rules: a tee mid-route, an elbow at the end
• Included in the 3D and IFC export — the draw-off point as a draw-off cock, not a fire hydrant
• The XLSX schedule counts them by diameter, like the rest of the fittings

Free easting/northing ↔ lat/long converter for the UK, Ireland and North America

A survey arrives in British National Grid, a US client sends State Plane feet, the GIS team wants latitude and longitude — this converter handles all of it in the browser. British National Grid (OSGB36), Irish Transverse Mercator, Irish Grid, UTM zones 1–60 and all 124 NAD83 State Plane zones, one point at a time or a whole table pasted from a spreadsheet, with CSV out.

• OS and Irish grid references in and out, e.g. TQ 30080 80340
• Metres, US survey feet or international feet on State Plane jobs
• Warns when the pasted columns look swapped, and says how far the browser transformation sits from OSTN15

Free pipe slope & invert level calculator — with a live long section

Enter any three of upstream invert, downstream invert, reach length and gradient; the calculator solves the fourth and shows it as 1:n, %, ‰ and mm/m at once, in metric or imperial. Paste a whole manhole schedule and the long section draws itself, with cover at every point and a warning when a reach falls below the minimum for its pipe size. One click opens the same points in the editor for a DXF.

Paste a spreadsheet table and get a profile right away

Paste a table from your spreadsheet — name, distance, ground level, invert level, diameter — and the long section is drawn immediately. Now inside the app too: start a new project from a pasted table, or paste the points straight into the side panel of an empty project.

More control over profiles and CAD editing

Enter water pipe centreline or invert levels, show bedding and cover fill with specified thicknesses, and choose branch chainage. The preview and DXF use the same chainage, with separate CAD layers for warning tape, bedding and cover fill.

Start a project from X/Y coordinates

Paste X/Y points with or without ground levels. The tool assigns names P1, P2… and calculates distances. Preview the route plan or a working long section, then keep your data when continuing in the editor.

Check your table and preview a profile before signing up

Paste points from Excel, correct elevations and preview a long section without an account. Keep your draft through sign-up or start from one of four examples with a sample DXF. Available in Polish, English and German.

Variable datum levels in the long section

Enable variable datum levels and set each new datum from a chosen position on any segment. This keeps a long route clear in one profile without changing actual elevations or calculations.

More profiles, clearer slopes and new objects

Create independent profiles while retaining settings, save your own defaults and keep long-section annotations easier to read.

• Equal-slope grouping, 0.1% rounding, minimum-slope checks, compact crossings with a short colored guide and optional collision markers.
• Bulk manhole diameters, a tee without duplicate labels, and retention or septic tanks with a wall inlet.
• Free object descriptions without a forced type prefix and reliable manual movement of PDF underlays.
• DXF export uses its own ALTIVO_ARIAL style, so text keeps its layout even in drawings whose Standard style uses Simplex; dashed lines are preserved too. Gravity-sewer defaults use invert depth, and a gas wall entry can include a small cabinet with a shut-off valve.
• A building-mounted gas cabinet now includes a floor slab and level marker, making it immediately distinct from fence mounting.

One secure session per account

A new sign-in now automatically signs the account out on the previous device or browser, preventing project access through an outdated session.

Roads and sidewalks on plan and profile

You can now draw a road or sidewalk crossing the designed utility and see it immediately on both the plan and long section.

• Pick the utility crossing point, choose the surface type and enter its width and plan length.
• Move the crossing with the centre handle and rotate the surface around the fixed intersection using either end handle.
• The crossing angle adjusts the width shown on the profile, and roads and sidewalks are included in DXF exports.

Buildings anchored to designed ground

Building parameters can now use designed ground as their reference level. The floor, walls, foundation and service entry move together to the proposed grade, with no manual offset from existing ground.

DTM: EVRF2007, safer coordinates and lighter profiles

DTM elevations are now available in the current PL-EVRF2007-NH or legacy PL-KRON86-NH vertical datum. The confirmed CRS, axes and datum are remembered with the project and carried into IFC georeferencing. PL-1992 requires a map-location confirmation, while adaptive sample reduction preserves terrain breaks without bloating the project.

Service entering the building above ground — through the wall

Building parameters now offer “Above-ground entry (through the wall)”: the service rises just outside the wall and crosses it at the height you set (0.5 m by default) — the way a gas connection is normally drawn. A protective sleeve through the wall can be added with one click. It all lands in the preview, the SVG and the DXF with no extra work.

Angle and distance rounding, angles on leader lines, blank point labels

Network settings gained a “Labels and rounding” section. Choose how precisely the profile prints angles (whole degrees, 0.1° or 0.01°) and distances (1 m, 0.1 m or 0.01 m). Horizontal angles can move out of the table row onto vertical leader lines at the nodes. You can also turn off automatic point numbering — new points are then created without a label, and a blank label is no longer drawn on the profile.

• Angles: whole degrees, 0.1° or 0.01°
• Distances and chainages: 1 m, 0.1 m or 0.01 m
• Horizontal angles printed vertically along the node line, above the table
• Unlabelled points — automatic numbering can be switched off

Network crossings: correct branch elevations and invert callout on the drawing

Automatic crossings with another network’s branches now show exactly the elevation that branch’s own profile draws — including the tie-in elevation, a drop structure at the connection and pipe-diameter differences. False collision warnings caused by the mismatch are gone too. The crossing label on the profile now states the crossing pipe’s invert (e.g. “Sewer φ200 bottom 64.04”), so it can’t be confused with your own pipe’s elevation in the table, and the Elevations panel labels the branch tie-in value with the manhole bottom note.

Buildings with a basement, a basement water meter and floor-elevation marks

Building parameters now include a basement: enter the basement floor elevation (straight from the architectural design) and the profile draws a second floor slab, extends the wall and seats the footing below the basement. The water meter set can be mounted on the ground floor or the basement floor — the service riser routes itself downwards when the meter sits below the pipe. The computed ground-floor and basement floor elevations are annotated with spot-elevation marks on the building wall.

Ground elevations from the Polish national DTM — one click

For projects in Polish coordinate systems (PL-2000 / PL-1992): fetch ground elevations from the Polish national DTM (GUGiK, 1 m grid) for missing nodes or all nodes, and optionally sample terrain along the route so the profile follows its shape between nodes. The CRS and axes mapping are detected automatically. DTM elevations are clearly marked as approximate and do not replace a geodetic survey.

Gas cabinet: mounted at the fence, on the building, or freestanding

Gas cabinet parameters now include a mounting option: freestanding (a service point on its foundation), at the fence, or on the building. A mounted cabinet is drawn the way it is built: a smaller box hanging above ground (50 cm by default, editable), with no foundation of its own, next to a fence post with underpinning or a building wall with its footing — on the side you choose. The elbow riser takes the gas pipe up to the bottom of the box.

IFC export tuned for Autodesk Navisworks

Pipes in the IFC model are now written as simple extruded solids that Navisworks reads reliably — previously the older "Legacy" method could skip them. There is also a new "Optimize for Autodesk Navisworks" switch in the 3D/BIM export dialog: it writes the file in IFC4 and adds the full spatial hierarchy (Project→Site→Building→Storey) so a network appended in Navisworks appears and groups correctly.

Paste multiple points when inserting into a route

The “Insert point” dialog now has the same “Paste points” box as quick point entry. When inserting before, after, or at a chosen spot on a segment, you can paste several nodes from a table or CAD, and Altivo cleans comments, headers and extra text automatically.

Route elevations and depth now shown at crossings too

In the column of a crossing with another network, the profile table now shows the route’s own elevations and depth at that station — terrain elevation, pipe axis and channel invert, depth and crown cover. Those cells used to be empty (and the axis row showed the crossing pipe’s level, not the route’s). The values are interpolated along the route between the neighbouring nodes, so a crossing column reads like any other. The same on screen and in the DXF export.

At a branch connection: main-route and branch elevations side by side

On a branch profile, at the first node (the tie-in to the main route), the elevation and depth rows now show two readings side by side: the main route on the left, the branch on the right. It covers the axis elevation, cover/depth, channel invert and its cover, and crown cover — for every network kind. The values split only where they actually differ (different diameter or tie-in level); when they match, a single number stays. The same on screen and in the DXF export.

External drop (cascade) at a branch connection

When a branch ties into the main route more than 0.30 m above the invert, you can now choose how the drop at the connection is drawn — just like an in-line cascade. Internal keeps the drop inside the connection manhole; external adds a drop pipe carrying the inflow down to the main route invert, as a gentle 45° ramp or a vertical 90° drop against the wall. Set it in the tie-in row of the “Elevations & depths” panel; the drawing updates on the branch profile right away. At the connection itself — on both the main route and the branch profile — you now see both channel inverts (the dno and the tie-in) and two pipe cross-sections on the manhole.

Branch slope and tie-in row

A branch segment (even a single-point branch) now shows its slope in the “Elevations & depths” table and can be edited directly. Every branch also has a tie-in row to the parent route — edit its depth, invert or cover there, and the app keeps the tie-in from sitting below the main route invert (empty = at the invert).

Per-branch calc direction, slope and depth

The “Elevations & depths” panel now lets you focus on a single route (All routes / Selected route toggle) and give a branch its own calculation direction, slope direction and default depth — independent of the main route. A lateral can fall toward the collector while the collector falls its own way; leave a field empty to inherit the network value.

Delete branches

You can now remove an unwanted branch in one click — the trash icon next to the branch header in the points list. It deletes all of the branch’s points, segments and objects (and any sub-branches), and you can undo it with Ctrl+Z.

Undo and redo

Every change to a project can now be undone and redone — with Ctrl+Z / Ctrl+Shift+Z (⌘Z / ⇧⌘Z on Mac) or the buttons in the editor toolbar. Dragging a point counts as a single undo rather than dozens of tiny steps, so reworking a route is fast and worry-free.

Groundwater level on the long section

You can now add a groundwater level to the long section: set one default elevation for the whole route or enter values at selected nodes and terrain points. The line appears in the preview and DXF export, and an optional table row prints the groundwater elevations in the profile columns.

Bends and elbows as node types

The node type catalogue now includes bends and elbows. On the long section, the symbol appears without extra setup as a circle on the pipe axis, sized to the carrier pipe diameter.

DXF export of branch profiles

The long-section DXF export now covers branches, not just the main path. In the export dialog you choose the scope: the main path only, the main path plus every branch (each as its own profile, stacked one below another in the same file) or a single branch. The plan export and the XLSX schedule already handled branches — now the long-section does too.

External drop (cascade) at a manhole

When the invert drop exceeds 0.3 m you can now choose how the cascade is drawn: internal (the drop inside the manhole, as before) or external — the inflow pipe still enters at the channel level and a second drop pipe carries the flow down to the bottom, either as a gentle 45° ramp or a vertical 90° drop against the wall. Set it in the manhole’s parameters (expand the object settings); the drawing updates on the profile and the DXF export right away.

Map underlay on the plan view — PNG, PDF and DXF

You can now load a base or design map as an underlay on the plan view and trace the network route over it. We support raster maps (PNG, PDF) with coordinate calibration and a vector DXF underlay that keeps the original layers.

• Load a map from a PNG, PDF or DXF file.
• Calibrate the raster to coordinates — the underlay lands exactly where the route is.
• Vector DXF preserving the original layers.

Free drawing and editing on the plan view

The plan view is now a full workspace. You add and drag nodes directly on the map, draw parcels and crossings as lines, and place manholes and fittings straight on the plan.

• Add and freely drag nodes with the mouse.
• Draw parcels and their outlines.
• Crossings with other utilities drawn as a line across the route.
• Manholes and fittings visible and editable on the plan.

Draw the ground line on the profile

On the longitudinal profile you can now add and refine the ground line by hand — useful when survey data is incomplete or you want to add points between nodes.

• Add terrain points directly on the profile.
• Adjust the ground line between nodes.

Export to a 3D IFC model (BIM, Revit)

Turn a finished profile into a georeferenced 3D model in IFC — ready to load in Revit or any BIM tool. Like DXF and PDF, the export runs entirely in the browser.

• 3D model of pipes, manholes and fittings.
• Georeference in the coordinate system you choose.
