CvtATL4toATL5
CvtATL4toATL5 is a file conversion utility developed by Abvent, designed to convert project files from ATL4 (Allplan 4) format to ATL5 (Allplan 5) format. Allplan is a professional CAD and BIM software suite used in architecture, engineering and construction. This converter allows users to migrate legacy Allplan 4 projects into the newer Allplan 5 environment, preserving data and enabling access to updated features. The tool is intended for professionals and organisations with existing Allplan 4 archives who need to upgrade their projects without losing work or starting from scratch.

1 suggestionNo information is publicly available about whether CvtATL4toATL5 has been updated with native Apple Silicon support or whether Abvent has plans to release a native version. The search results returned are irrelevant (they refer to ChatGPT). We recommend contacting Abvent directly to inquire whether a native Apple Silicon build or update is available or planned. Given the specialised nature of this tool and its focus on legacy file format conversion, it may have been superseded by built-in conversion features in newer versions of Allplan itself—you may want to check whether your current Allplan installation includes native conversion capabilities before relying on this standalone utility.
