If the elevation structure of Project1.rvt is completely the same as that of Project2.rvt, after importing Project2.rvt, it will be combined with the imported Project1.irvt automatically to form a complete TAS (TIO) project file. With TAS (TIO), you can import Project1.rvt first after that, continue to click Import RVT File, and then select Project2.rvt to import. If a project is consisting of three independent files: Project1.rvt, Project2.rvt and Project3.rvt. That is to say, if a project is consisting of multiple RVT files, TAS (TIO) supports importing them all to form a complete project. TAS (TIO) supports importing multiple RVT files consecutively.


The supported RVT formats include files created in RVT 2013~2020 version.

To import RVT files you have got into TAS (TIO) directly for quantity takeoff, you can use this function.
