What's new

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.

Automatic ground elevations are clearer when pasting points

When you paste points without ground elevations, Altivo still fills them in automatically, but the Points panel now shows those values in grey. Enter the first elevation by hand and the following automatic points immediately take the same level. If you later enter a new elevation at another point, the automatic points after it switch to that value — no need to retype the whole table.

Lost map underlay? Drop it in with one click

After loading a DXF or raster map it sometimes landed far from your drawn network and was hard to find. The new “Place at point” button fixes that instantly: click the button, then anywhere on the plan, and the map centre jumps right there. It hands straight over to move mode, so you can fine-tune by dragging. Plus, the “Fit to screen” button now frames the map too — one click shows your network and the map together. No more hunting for a map that flew off-screen.

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.

Branches grouped in the elevations and segments panels

The “Elevations & depths” and “Segments” panels now split their rows into the main route and each branch — just like the points panel. No more branches blending into one list: every group collapses, and it’s instantly clear which route a point or segment belongs to.

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.

Add points onto a chosen branch

In the plan view, next to the “All networks / Active only” switch in the top-right corner, a path picker now appears whenever the network has branches. Set the active path and the points you add by right-clicking on empty canvas go to its end instead of always the main path. The picker only shows once at least one branch exists. New points also inherit the terrain elevation from the previous point by default (shown and editable in the add dialog), so points no longer end up without a ground level.

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.

More precise manhole and chamber XLSX schedule

The XLSX export now separates manholes from chambers in the detailed schedule and shows the drop type at invert steps: internal, external 45° or external 90°. The schedule now matches what is drawn on the profile more closely.

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.

Hectometers marked on the profile

A hectometer ruler now sits below the profile table: the conventional half-filled circle every 100 m on a stem from the table’s bottom edge, larger at full kilometers, with running hectometer numbers underneath (0, 1, 2, …). Per-node stationing is printed as before.

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.
