In Navisworks, to set up a quantification standard according to a non-native standard is time-consuming not because it is difficult, but because it is tedious. Standards typically have thousands of items within their classification structure, and each one must be added manually to the Navisworks File. I have looked on the internet to see if they are easily available, but they are not.

The typical setup is to use an exported XML file and to edit that instead, then reload it.

You can use the freeware Notepad++ for editing XML files:

Once it has been created, it can be exported and reused again. The method is discussed in this blog:

What if you don’t have the time to set this all up? What if you don’t want to set up search sets to populate quantity take-off? Well, there is a relatively simple way to do something that does not conform to a standard, but that does conform to a Revit project structure (usually levels first, then categories). This is another reason why it is a good idea to have only the necessary levels present in the project. In fact, one could plan the level structure based on the quantity take-off that will happen.

How easy is it? Just set the project up for “None” as the quantification standard.

Now drag the Revit file from the Selection Tree onto the Quantification Workbook.

The take-off is automatically done as per the Revit file structure.
