| AR Planning Software, 2023-2024 |
|
In this project, we developed the first AR planning software on the market to streamline the workflow between cadwork 3d (a professional timber construction CAD software) and the AR-based fabrication system from Instructive Construction AG (incon.ai). This software lets planners generate, view, and edit AR-ready models and instructions directly in their native CAD environment, cadwork 3d. The AR building plan is synchronized from cadwork 3d to workers’ AR devices on the shop floor.
The software integrates seamlessly into the cadwork 3d environment. A user selects a building group element and can directly generate an AR building plan from it, which is then linked to that specific building group. The AR building plan comprises a series of AR building steps, each displaying a set of parts and AR instructions (e.g., dimensions, text). This AR building plan is generated online and then streamlined back into cadwork 3d. Users can add missing instructions or custom text comments directly within cadwork 3d. To ensure maximum usability and applicability, our team conducted a thorough examination of the current workflows used by timber planners at eleven timber companies (e.g., ERNE AG Holzbau, Blumer Lehmann AG, Abt Holzbau AG). We interviewed them about their planning processes and observed their planning and production teams in their daily activities. The resulting insights were organized into Epics and User Stories, which formed the basis for the software and UI development. The AR planning software’s architecture consists of several independent packages: the plugin, COMPAS cadwork, the cadwork3d API (cwapi3d), and the incon.ai API. COMPAS cadwork and cwapi3d are publicly available at the following links; the plugin is distributed by incon.ai. COMPAS cadwork: https://github.com/gramaziokohler/compas_cadwork cwapi3d: https://github.com/cwapi3d/cwapi3dpython The AR planning software is already in active use and has been successfully deployed in conjunction with the AR fabrication system by several timber companies.
