All the latest NBS and industry news and stories
NBS worked with Bentley to provide a new plug-in, allowing OpenBuildings Designer users to develop model information in parallel with NBS specification data and guidance, embed key references in object properties and check for warnings and errors as things change, reducing risk, improving productivity, and increasing quality assurance on projects.
Beginning with Openbuildings Designer Update 10, the Bentley and Chorus plug-in is free and available only with the UK, ISO19650, AU and US datasets. This version and its datasets should be available via your existing subscription via the software download page in the connection centre. Alternatively, use the link below to contact Bentley for further information about OpenBuildings Designer.
Access the plug-in
Watch the following video to find out how to get started with the plugin.
