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

1. Import. Select the RVT file you want to import.

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

TAS (TIO) supports importing multiple RVT files consecutively. That is to say, if a project is consisting of multiple RVT files, TAS (TIO) supports importing them all to form a complete project.

If a project is consisting of three independent files: Project1.rvt, Project2.rvt and Project3.rvt. 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 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.

If the elevation structure of Project1.rvt is not completely the same as that of Project2.rvt, you need to click Reversely Create Zone   to form a complete TAS (TIO) project file.

2. Floor Settings. Generally, select the ground floor as the reference floor.
   

In Advanced Settings, you can set the floor names and heights of the imported RVT project.

By default, the floor names and heights of the original RVT project are taken as the values for Floor and Height. To adopt floor names and heights of TAS, select Name in TAS and Height in TAS. This operation is not recommended.

By default, Match the lowest floor in RVT file to the foundation floor in TAS file is selected. If clear the selection, one more foundation floor will be added to the structural foundation of the original RVT project imported.

3. Element Settings. Select the floors to import, and select element types and materials to match.

• Select floors to import. In the list of Floors to Import , select which floors to import.
• Match element types. Generally, after importing RVT elements, there will be default element types matching with them. For example, if the value for Element Type in RVT is beam, the default element type in TAS (TIO) will be Beam.

If you want to modify the default element type, under Import as > Type in TAS, modify the corresponding element type.

If you want to batch modify one element type, after modifying one cell, move the pointer to the lower right corner of the cell, and then when the pointer changes to a plus sign, drag the selection box to modify mutiplte element materials. Because the element materials in RVT do not match with that in TAS (TIO) one by one, a default material is always given for matching.

If you want to modify the default material match, under Import as > Material in TAS, select and modify the corresponding material. The method is the same as that in 2) above.

4. Model Preview. Browse the whole model, and then determine to import the model wholly or partially. By default, Import All is selected. To import models partially, click Import Selection, and then select the portion you want to import. To specify the insertion point to import the model to TAS (TIO), click Set Insertion Point.
