This option links the IFC, RVT, DWG, PDF file within the project. Linking is the best option to visualize external content for coordination purposes. The IFC, RVT, DWG, PDF file is automatically updated when you open the project and can be manually updated at any time. The IFC, RVT imported model is treated as a unit. The model is displayed in both 2D / 3D and the associated BIM data can be viewed.
Link enables to assign IFC floor structure with project floor structure. Each imported floor is displayed on the corresponding project floor.
