Archicad 29 crashes when updating drawings linked to another Teamwork project

Summary

Archicad repeatedly crashes when updating external drawings whose source layouts are stored in another Teamwork project.

The destination project uses layouts and title blocks linked from a separate Teamwork master project named “AC29 base edile”. The links appear to be correctly configured, but the drawings remain marked as “Not yet read” or “Outdated”. When Archicad attempts to read or update them, it crashes.

Environment

Archicad: 29.2.0 build 5003 ITA FULL
Collaboration environment: BIMcloud as a Service
Project type: Teamwork
Computer: Mac mini 2024
Processor: Apple M4
Memory: 32 GB RAM
Operating system: macOS Thaoe 26.5.2

Project configuration

The destination Teamwork project contains external drawings linked to layouts stored in another Teamwork project.

The source project is used as a shared master file for:

master layouts;
title blocks;
layout structures;
project information displayed in the title blocks.

This workflow allows title blocks to be centrally managed and automatically updated across multiple projects.

Steps to reproduce

Open the destination Teamwork project.
Open the Layout Book or Drawing Manager.
Select a drawing linked to the external Teamwork master project.
The drawing is shown as “Not yet read” or “Outdated”.
Update the selected drawing or choose Update All Drawings.
Archicad attempts to read the source project and crashes.

Actual result

Archicad crashes while reading or updating drawings linked to the external Teamwork project.

The drawings cannot be reliably updated even though the links and source paths appear to be correct.

Expected result

Archicad should read the source Teamwork project, update the linked drawings and title-block information, and change their status to “Up to date” without crashing.

Reproducibility

The issue occurs consistently when updating the affected external drawings.

Additional information

The source is a Teamwork project, not a local PLN file.

No reliable workaround has been found. Exporting PMK files or duplicating title blocks manually may avoid the crash, but these options remove the automatic connection to the central master project.

Crash reports, screenshots, source and destination project files, and a screen recording can be provided if required.

Business impact

The issue prevents the use of a shared master-layout and title-block workflow across Teamwork projects and creates a risk that outdated information may remain in issued drawings.

Please send the bug reports off, take note of the report number and then follow up with you local support asking to investigate that report number.

I am not too familiar with teamwork, but you would need permission to open and update the other teamwork files.

Regardless, it should still not crash, it should just say you don't have the correct permission.

Are all of the files saved with the same build version of Archicad?

I believe teamwork can be a little fussy about that.

Also does it help if you also open the other teamwork files at the same time so Archicad is not trying to open them in the background.

Barry.
