They are 3d models of chairs, tables, stools, armchairs and everything that is functional and indispensable to take advantage of a space. The models are made in detail and useful for interior design projects. 
Various BIM objects can be combined within one file through the parametric BIM models. How? For example, by uploading the 3D model of a table, it is possible to associate it with models of chairs produced by the same brand. Therefore, Revit families allow combining multiple models of multiple products thus having multiple design alternatives. 
The downloadable templates are useful for those who conceive the project both bi-dimensionally and therefore need to import ready-made and designed cad blocks to their project, and for those who want, during the design phase, to process realistic photo views (renderings) and use the 3D models, material libraries and textures made available by Syncronia and its partners.   
In addition to the models and CAD blocks available to users, the catalogues and technical information in which the finishes and materials with which the individual products are made are specified.
