Position several 3D objects on your AUTOFLUID networks in seconds

Released on 21.05.2026

New command “Position a 3D block”

Just a few months after its release, it was already popular for its ability to insert 3D blocks from libraries into modelled networks with just two clicks. In its latest version, the “Position a 3D block” command allows you to position all 3D objects – and even groups of objects – on your networks even more easily.

Position all 3D objects automatically

You are not limited to 3D blocks. The “Position” command can align all 3D objects within your modelled AUTOFLUID network. The command still works in the same way: simply select the two entities to be connected to position the relevant objects or groups of objects.

Position several 3D objects at the same time such as an entire set of components

As visibility is limited in 2D, it can be tricky to draw a series of fittings on a vertical pipe. When you aim to model in 3D, it’s easier to start with drawing it on a horizontal pipe and then model in 3D. Now position the fittings all at once on the vertical pipe, and you’re all set!

Generate each 2D view of a 3D equipment block, ready to use

Released on 25.09.2025

New command “2D views of a 3D block”

You can use non-AUTOFLUID equipment blocks on your AUTOFLUID network. But you still need to have the right view and the right block to insert into your plans, your detail drawings or your cross-sections.

If you have the 3D equipment block, the 2D views command is for you. AUTOFLUID automatically prepares the six views of the 3D object, leaving you to simply select which one to connect to your network.

Your 3D blocks on your AUTOFLUID networks in just two clicks

Released on 25.09.2025

New command “Position a 3D block”

When modelling a 2D AUTOFLUID network in 3D with AUTOBIM3D, the material retains a generic appearance, with just enough detail to make it easy to handle. But despite this advantage, sometimes you may need more realism in your visualisations.

The new command ‘Position a 3D block’ does exactly that. Regardless of the angle and distance of your block, select the part of the equipment that connects to the network, select the network, and the block will automatically position itself. Once in place, the control remains active to switch the equipment orientation on the network.

Dynamic calculation of Air, Water and Supply network sizes

Released on 22.04.2024

Simple, quick and intuitive commands that work out all your duct sizes in a diagram of your network.

Before drawing your HVAC and plumbing designs, it is always necessary to calculate the size of each segment of your network. AUTOFLUID already facilitates these calculations based on a quick diagram of your network. However, the new dynamic calculations diagrams take this to a whole new level.

Need to change the flow rate of a branch? The section sizes for your entire network are recalculated instantly. Do you need to add more branches to your network? Their flow rates are automatically included in the global calculation and all results are updated.

You can test different calculation parameters, redesign your network as your project evolves, or simply make a mistake – AUTOFLUID INFINITY’s dynamic section calculation commands will work it out again for you.

Tool ribbons in AUTOFLUID INFINITY

Released on 30.01.2023

The AUTOFLUID suite tool bars have now been replaced with a completely new design ribbon. It has a better structure, providing direct and therefore quicker access to controls which are now grouped together in panels.

Tool ribbons in AUTOFLUID INFINITY INTERFACE

The ribbons provide a better visual relation to the position of each tool. A unified colour scheme for the whole interface and new icon graphics make identifying the controls significantly easier.

These legibility and comfort improvements speed up your interactions with the Suite’s various controls and reduce fatigue when using the software for long periods of time. Even learning to use the software is made easier.

Productivity in design

Released on 30.01.2023

You can be more productive when you work with greater fluidity and ease, you can focus on the most important thing: the quality of your project. Getting more productivity out of AUTOFLUID users means paying attention to every detail and getting the most out of each interaction with the application, whether selecting a duct or rendering a view quickly.

Create instant automatic cross-sections in AUTOCOUPE

INSTANT cross sections WITH THE NEW AUTOCOUPE (beta)

A beta version of the new updated AUTOCOUPE application is now available. Just select the ducts you need on the plan view to generate a cross-section view of them. The view options can be used to add a floor slab and/or suspended ceiling.

Please note that AUTOCOUPE is still under development. Until the final version is released, it may produce incomplete views that should still be quite easy to complete manually.

VERTICAL DUCTS

All good things come to those who wait! It is now possible to connect a vertical duct to the top or the bottom side of a horizontal duct. Select the duct configuration and it will be drawn immediately.

EASY SELECTION

No need to click on a specific line to select an object when routing. For greater flexibility, any line of a network can now be used to select it.

EDITABLE ZONES

Improvements to the zoning tool now provide even greater flexibility. Once the limits are set, the zone can now be warped using the magnetic grips.
