The Clash Detection tool in OpenBuildings Designer helps to identify interference between elements in 3D models and resolve them. It is used to find hard clashes created by overlapping 3D geometry and soft clashes based on a specified clearance value between elements.
In this video displaying an example layout of an existing office, chairs represent the effective occupied area of a person’s physical workspace. By checking the clearance between the adjacent chairs, we can identify conflicts in workspace safety for social distancing and make informed decisions to amend them.
To perform a clearance check, a clash job is created in the Clash Detection dialog to find clashes between objects in Set A and/or Set B. The level A-FURN-SEAT, on which the chairs are modeled, is added to Set A. Elements added to set A are displayed in red while other elements and background are in grey to provide clear visual feedback. The desired soft clearance value surrounding the elements in Set A is entered and the option to perform a self-check is enabled. Clicking the Process button performs the safe distancing checks surrounding the chairs in the model.
Clearance clashes identified in the model are generated in the form of tabulated results for easier navigation and review. Clashing elements are highlighted in red and blue and are automatically zoomed in within the view windows. Clash results can be grouped, marked up and exported to Excel spreadsheets. The furniture layout can be modified to resolve any safe distancing issues and re-verified by processing the clash check again.
