With Hotlinked Modules, external ARCHICAD files such as modules, plan files and Teamwork projects can be inserted into the currently open project (host). Hotlinked elements inserted into the host reflect all modifications made to the source files (as soon as you update the hotlinks). The elements of hotlinked modules are included in the Project, which means that even if the hotlinked source file is not currently available, the Modules are still present and visible, although they cannot be updated as long as the referred source file is absent.
ARCHICAD also supports the hotlinking of a module into other modules. These are called nested modules.
ARCHICAD’s Hotlink Manager dialog provides an overview of the hierarchy of even very complex hotlink file structures, plus feedback on the status of the individual modules (updated, outdated, broken). Updating the entire hotlink module structure, or just individual hotlinks, requires just a mouse-click.
For example, Hotlinked Modules can be used to manage the repetitive structures of buildings, such as hotels or offices, which have a large number of identical rooms: you can modify all instances in a single step. Moreover, the same structures can be used in multiple projects. This is also a good way to subdivide large projects into easier-to-handle smaller files and to reduce the file size of the host project.
If a building contains several identical stories, you can hotlink the typical story of the host file into the other stories. In this special scenario, the hotlinked module source is contained within the host file.
