BIMx functionality

(note by moderator: this discussion diverged from another thread, which you can find here:

I would also point out in your letter that they took a perfectly great mobile viewer like BIMx and ruined it... all in the name of opening bigger models for big firms... forgetting the little guy.

I feel you. I had to submit a few renderings for a client a few weeks ago, the package also consisted a BIMx submission for them to check the design. They asked me not to have the latest modifications in the BIMx (pretty detailed furniture and other assets, so it was additional work to get them back into AC), because they wouldn't use it anyway, due to the low quality look of it.

The only advantage left for it is the inclusion of layouts, which are useful for construction site visits, but the presentation value tends to zero - almost everyone wants the quality of other engines (UE specifically) for walkable model content.

We actually use Enscape for presentation, it works inside archicad so no switching back and forth between programs, we do not use Twinmotion and BIMX; it is so much faster to do everything inside Archicad. Construction output in pdf, dwg or ifc. I personally never really understood the added value of BIMX

It is useful to be able to export all your floorplans/sections/etc. with your model. Like this, for example:
https://bimx.graphisoft.com/model/80899f67-550a-44c2-8a52-2b6c59e2f679

It's pretty useful - just don't try to use it as a visualisation tool, because you'll end up embarassing yourself...

Yes, this is a nice example for showing stages of construction, visually it's not something clients would use for sales purposes, or what I would present for decision making. For these, BIMx is rather underdeveloped look-wise: your model too has some off-putting AO splashes on the walls, textures are low-res, there aren't even baked reflections, and to get this result, it takes ages.

The threshold for low-end viz is way higher these days, and the high-end is somewhere in the stratosphere: https://www.facebook.com/nu.ma.arq/photos/a.2506501652759924/4114308085312598/

From the Graphisoft website:
"Archicad’s professional architectural visualization tools translate your conceptual designs into compelling imagery of future buildings. Bring your models to life, inspire the audience, and invite stakeholders to engage with your designs."

It would be awesome to access basic render passes to produce composite imagery out of the box to meet requirements without having to open a 3rd party modelling software that has access to some state of the art rendering engine ("traditional" or realtime) - Cinerender just isn't one.

The Twinmotion connection and UE Datasmith are steps in this direction, which are nice, but you lose the ability to have an integrated experience between the design and its documentation.

You either
- duplicate work (having to model everything twice)
- have a mismatched or incomplete experience (showing a model and disconnected PDFs for instance).

Even if you duplicate the model, you will struggle with the high-poly assets available elsewhere (C4D, UE, Twinmotion, Blender - you name it), or have a really simplified representation in BIMx (that can mislead the client).

BIMx is very good for showing construction information on building sites - one of the best in this world. They just need to add additional features of pre-backed textures.
By the way, render quality and pre-baked textures made by Lightscape (old Canadian radiosity visualization software) were good enough and can be used something similar in BIMx - most important - speed of production and small size.
To be fully accessible from website - it's also the power of BIMx.

In my opinion bimx is not intened for visualization purposes for clients, as it can actually play against you if they´re not tecnical people. Its more for on-site visualization with contractors where you can see the basic model with plans and sections, without textures and other hoohas, and for that it works great! Granted, as Mr. Rex said, if it previously had some basic nice quality and they downgraded it, then thats not good (havent used the newer version).

Visualization, with its obsession on realism is rapidly approaching to porn, and clients are becoming more and more spoiled because of it. Renders also suffer from the uncanny valley phenomenom: as it gets more realistic, it needs more detail to look better, eventually becoming unfeasible to model within time and economic constraints. Ive seen clients complain because the water reflection on the pool didnt look that good.

Hence, you strip detail to show what matter, that is, BIMx. Yet, If you need more realism for clients, then Enscape, Twinmotion or UE are the way to go.
The other thing about BIMx is the way they deleted useful features from what is now BIMx Legacy. Can you imagine the uproar if ArchiCAD did away with parallel projections in the 3D window? No 3D plans, or side views, no axons... perspective only? Yet somehow the developers thought this would be a good idea to strip from BIMx.

I think BIMx can have a 'rant' all on its own.

I strongly agree with Rex here. Removing functionality that was previously there is very unprofessional towards my clients.

Virtual Building Explorer started out as just that and had zero functionality for building professionals on site. That there is a pro app that offers this now, is fine by me, but for a lot of us there also clients that 'just' want to view their project in 3D and show it off to friends etc. These are also 'big' projects. We have had a lot of villa projects ranging from 900 m³ to 2.000 m³ (or 700k euro to 1.5 m euro) over the years and our clients were very pleased with BIMx presentation and being able to explore their new homes etc

I also do not care for the arbitrary shifting of functionality over to a pro app, which is intended for building professionals on building sites, but was previously available as presentation options in a free app. We pay a fairly hefty subscription, which includes having the ability to host our BIMx projects on the official GS server for it, I do not see why my clients need to buy pro apps just to 'unlock' the nicer presentation of their new home.

I hope Autodesk buys Graphisoft as well. It will pay more attention to our inquiries.
