For managing our business and project libraries we would like to have the possibility to save system families such as walls, floors, roofs, ceilings and also ducts, pipes and trays as loadable families. When these system families are available in the family editor we can start to make reusable parametric content. For example a floorplan layout. How much freedom will it give the AEC market if we could save a piece of a building as a part just like it is possible in Inventor, FreeCad or Catia. It will give us the possibility to make fully parametric façade elements, floorplans and modules. Now we have to work with linked files. Each time we want to change something in a Linked file we have to open the file and reload it again. Instances that are slightly different have to be a different linked file. Managing the families within all these linked files is hard. Because it’s not possible to use the same linkend file in multiple forms were only some instance dimensions are changed. A linked file can’t be modified by it’s dimension parameters.
