Dear GS, As a long-time Archicad user, I switched to the Collaborate plan on the understanding that it would guarantee me access to all of Archicad’s functionality. Why are you suddenly introducing a new Max plan and starting to restrict some functionality in Collaborate? An...

Dear Graphisoft, I've been an Archicad user for 25 years, and for all that time I've welcomed every new feature, big or small, with genuine enthusiasm. You even quoted my praise in the press release for the previous version. With Archicad 30, though, I have nothing to praise...

macOS 27 Golden Gate is here, and like every year, it's time to dig around and find out how Archicad runs on it. So far, the only thing I've found is an post from August that says pretty much nothing about Archicad 29. I know the universal answer is "don't upgrade." Still, I...

If an IFC model being hotlinked into Archicad doesn't contain layers in IfcPresentationLayerAssignment, all elements are stored in a single layer by default. This complicates further work when you want to display only terminal HVAC units, or hide distribution runs altogether...

If you caught the news a few days ago about the addition of the still-experimental computer use feature to Claude Cowork and Code*, and wondered whether it could work with Archicad on its own — the answer is yes. My experiment is here: https://youtu.be/d4GDtEw_qC4 The prompt...

For developers it’s a nightmare, but for us users it’s a huge opportunity. I’ve already vibe-coded a number of add-ons and other tools myself, some of which I share and which are used by the local community in our market. And in many discussions I’ve always argued that this ...

I have to stand up for GS here. I don’t think any such club exists, and I don’t get the sense that anyone gets noticeably privileged access to updates and the latest features. I was part of the Graphisoft Insiders group for a while (I left at my own request this summer), and...

Mohamed, thank you for your reply. It’s both reassuring and promising. I’ve been a bit skeptical about the MCP development so far myself, as I felt it mostly covered tasks that are already fairly easy to achieve with your own MCP server, at least for anyone with a bit more e...

You’re not out of the game – you just probably don’t have the official MCP. But it’s no problem to build your own; with Claude’s help, for example, you’ll have the basics in a few dozen minutes. Plus, you can use Tapir in it and do even more interesting things. The official ...

It’s computer use. Besides, my post is about six months old, which is ancient history in AI terms. MCP is far more efficient for working with Archicad. That said, computer use still has its place in some workflows, and it has come a long way since then too – just today I had...
