Is there at plan to give us the option to export to FBX in the future?
I see that many users talk about it but turn it to that there now is a solution to it by Datasmith to use with Twinmotion. But not all of us work with Twinmotion.
I work with 3D Studio/VRay and Unreal for many of our projects and sure Datasmith is nice to have in Archicad, but not to have the chance to export to FBX for 3D Studio or Blender is really a bummer. To not have the opportunity to have linked projects with FBX-files makes revisions a really hard days work.
FBX-Files is used by many 3D software and gives Archicad projects the chance to go in many different ways for presentation to clients. To just say we have Datasmith is to say that we only work with Twinmotion and Unreal, I don't just want to work with those, I want my projects to have the opportunity to expand in many other 3D applications.
Maybe I missed something but I cant find the Export FBX anywhere.
You are right that Twinmotion addon for Archicad has this feature. I haven't used it much, but maybe someone who does can chime in and let you know if it is still possible to install with ArchiCAD25.
I believe there was a 'free' license with AC22 or AC23 (can't recall). Before that there was a free 'older' version you could trial indefinitely.
You mention working with Unreal. Twinmotion uses Unreal engine, as far as I know.
For 3D studio there is direct export from Archicad to 3DS.
If you open 3D perspective and go to File > Save As, you can see all the possible 3D formats you can export to.
Yes, Twinmotion uses the engine from Unreal and I preferer to use Unreal to our projects.
Yes, we have 3DS but the FBX format is universal with many other 3D Application such as Blender, Unity etc. For me today I'm fine with the workflow with Archicad, 3D Studio and Unreal but without the FBX the workflow is broken cus you cant use the link properties that makes new revisions to update in 3D Studio easy to manage. As far as I know.
But it's not just for me, I think that removing FBX is a very sad thing for many user who want to export Archicad projects to work with in other 3D Applications.
You can just install the datasmith plugin without having to install TM or UE. Then you can export a FBX model you can use in any software. I actually use this method for working in 3ds Max + Corona and it works perfectly!
edit: i was wrong.
I just checked this and indeed, installing the Datasmith Connection will not make it possible to export as FBX.
The Twinmotion file option is what saves as FBX, but Archicad 25 no longer has this option (there is no longer Twinmotion plugin for AC25); it has only the Datasmith Connection, which saves in ".udatasmith" format, not in ".FBX" format.
I don't know about FBX, but I believe there is now a Twinmotion plugin for AC25 Twinmotion | Plugins - Unreal Engine
Yes, it is the Datasmith Exporter. I have installed it and checked it. It will save a *.udatasmith file format from Archicad, not an *.FBX file format.
The Direct Link for TW does not support AC25, only earlier versions. You can find that if you click the "View archived versions" link on the webpage you posted.
The lack of fbx export truly brakes a very typical and reliable workflow. The partial solution, which I commented about in a different topic, is to use the new Save As .rvt.
However this comes with 3 types of issues:
1. Its slower than FBX
2. Objects in 3d, that are cut by the Cut planes are still exported as a whole object (including nested objects in them).
3. It can only be used with versions 2021 or higher.
Thank you very much for raising the problem!
To my knowledge, the FBX export function was made available by the previous Twinmotion DirectLink addons. Unfortunately, Twinmotion has shifted to their new Datasmith format, thus this function is no longer available.
We have entered this request into our Wish List database (please refer to it as IDEA-4296). Hopefully we will be able to reimplement it in the future!
I am very sorry for the inconvenience! Thank you very much for your understanding, and have a great day!

The thing about FBX is that it has become the DWG of 3D file transfer. Plus, the KISS method (keep it simple stupid) works best with FBX. The old direct-link and now Datasmith linking requires to many pitfalls compared to simple FBX use. I also use AR in some of my presentations. I plop the model down on a conference table and the attendees can walk around the table with their phones viewing the model interactively. It's a lot of fun and effective. This method uses FBX in as well. It's a rich transfer format that any top tier program should have.
Please expedite the request to R&D to develop this export option.
I may be a bit cheeky but here is a link to the FBX SDK:
I too am frustrated by the loss of FBX output, it significantly impacts on my workflow.
I understand that it's not up to Epic Games to provide me with this functionality, as I'm not using it with Twonmotion but Graphisoft please bring back this functionality.
FBX is ubiquitous in the 3D graphics world.
I actually have to have a subscription to SketchUp to save as SKP from Archicad, then to FBX so I can bring it into an AR app. Before I used the TM out option (FBX). I'd think it's important to have a path to an AR app in 2021. I've been using Arki on iOS.
We just upgraded our projects from ac22 to ac25 in our office (we have approx. 40 licenses) and realized the lack of the fbx-exporter. This is a huge problem, since all our premium visualizations have been using the pipeline of exporting to fbx and then linking it to 3ds max. The benefit of linking is that updating the model is very fast since you don't have to set up materials and additional settings again each time the design changes.
In ac25 for very large projects all the other export options take ages to finally get to an fbx. In one of our largest projects saving as fbx used to take under a minute in ac22 for the building and about 15 minutes for saving detailed furniture in a separate view. In ac25 the only "fast" way is saving to rhino-file first and then fbx from there. This will take at least half an hour for the building alone. I gave up waiting on how long the furniture would take after an hour. But the biggest problem is that I can't save from rhino fbx-model that is split by material. With sketchup and blender importing a dae-file had been going on for an hour when I decided to surrender.
The only real option for now is saving a pln in Archicad first to ac24 and an fbx from there. (And in the future ac26->ac25->ac24 etc.)
I can't emphasize enough how good and important the previous fbx-exporter was. It was fast, easy and reliable. I'm sure this is a significant problem for all the archviz artists using 3ds max. I sincerely ask you to seriously consider to reimplement fbx-exporter in the future.
Hey, I have found a workaround for this issue! (at least for 3DS Max users)
The RVT format (revit) format is really an FBX file under the hood. In the past I had used the RVT to link to max, however, when I discovered MAX really treats the RVT format as a "special" FBX file, I just started to use FBX instead.
Anyway, the new Archicad has a RVT exporter! (RVT 2021 to be exact, so you have to use this solution with 3DS Max 2021 and above)
So you can use the RVT as your "FBX" link. I tested it and it works!, it retains your surface material definitions, and "some-what" retains a good enough naming convention so you can identify Archicad elements.
How ironic is it that an Autodesk competing product gives the solution for Epic's problem it created for Archicad users...😀
Hope this helps you out, it certainly helped me!
I'm not sure how the RVT file is really an FBX under the hood, but it sounds like that's useable workaround for those with 3DS Max. Presumably 3DS Max can save the model out as a FBX then. The Archicad community got something it needed through the Twinmotion plug-in and when that changed a lot of people were left without a function they had become dependant on, not just for Twinmotion.
It should be no surprise that Autodesk products work with RVT or FBX as they're both Autodesk formats.
I did try that also, but unfortunately rvt-file is much slower to export from Archicad and much slower to link to 3ds max too... I'm working with a large school project and it used to take under a minute to export fbx and 5 minutes to update the link, but with rvt-file the exporting took half an hour and linking to max at least a couple of hours. I wasn't paying attention to how long it took precisely since it had been going on for an hour already in the background.
With small to medium sized projects this might not be an issue, so I do hope it will be useful for some users 🙂
Ohh wow, I see your point. I do agree that FBX would be much much faster. other possible suggestions are:
Break the project into modules and export/Link modules as separate smaller RVT files
If you really want the use of FBX and willing to jump through another hoop (free of cost), then you can download unreal engine, which is free, link via datasmith to AC25, and export as FBX from unreal and link to MAX. (i Know its not ideal, but this workflow is free of cost)
Another solution that allows you to link to MAX is: using the SKP format, (which i find is the most accurate export, second to FBX ofcourse). MAX will import SKP files natively, however, you cannot keep a link to AC25 via an SKP export, and you will lose a suitable object naming convention... however!... you can link that Max file as an Xref Object to another max file, which will keep all objects and materials from MAX file containing the SKP import. (I'm sorry if this sounds confusing... here is a simple diagram
AC25 --> SKP_export --> MAX SCENE #1 --> XRef Object (link) --> MAX SCENE#2
The Max Scene #1 - its only purpose is to provide the ability to import via an SKP file from AC25... IMPORTANT>> each time you do an update you would delete the object and reimport the new updated building SKP. (this is why you WOULD NOT add materials or modifications in max scene #1)
The MAX Scene #2 is for doing all your edits, material manipulation etc. The idea is that when you re-import an updated SKP into MAX scene#1, you would update the link in (or simply close and reopen the) MAX Scene#2. This should keep all your material definitions for any existing polygons (elements) whilst updating new objects coming from the AC25 SKP import in Max Sene#1.
NOTE IMPORTANT: Any Objects you modify in the source AC25, you will lose the material or any modifiers you added to them in the MAX scene #2. but all your other unmodified source objects will remain intact.
Yes, I know it's a bit convoluted, but it should work. (at least until Graphisoft creates their own FBX exporter for AC25)
Also note you can use this methodology with any other exports from AC25 (however I find SKP to retain the most accurate representation of your AC25 model)
Another "hoop hopping" solution to get an FBX into max coming from AC25 is to export an SKP file, Open In Sketchup Pro (you will need a sketchup Pro license) then export as FBX and link to MAX.
This I have not tested, however, you can try and tell me how it works for you. Using the method from "Solution #3" however via an IFC export, (I believe the IFC export from AC2 should carry over more data compared to the SKP export, however you will need an IFC importer for MAX, you can get it here: http://ifcopenshell.org/ifcmax
