You will be able to find the QTO menu as the second menu in the information panel.

This feature lets you view and export a property list of the objects that are selected in the 3D viewer or tree panel. With this list you will easily be able to get accurate measurements of the quantities of different objects in your model.

To get started, please select an object in the 3D viewer or tree panel to display its properties and related information in the inspect menu.

After having selected some objects, the QTO menu can look something like this:

This article contains information about the following topics:

Filter and export

With the filter bar you will be able to filter for any of the values in your properties.

Note: If your filter is not applied it might be because your filter was not accurate enough. Please supply more information for the right rows to be filtered.

The QTO list can be exported to Excel or CSV by clicking on the export button.

Quantity take-off list

The quantity take-off list is a list of all properties, quantities and materials in your selected objects.

Header row

The first row of the quantity take-off list contains the group that each of the properties that belongs to the selected object(s) belongs to.

If any of the objects contain properties that are not part of any property sets (PSets) they are gathered in an empty group in the first field in this row.

Possible property groups can be type, material, property set (PSet)

In the second row, names of properties within their groups form the columns that are available in the table.

The two header rows can look something like this:​

Object count

Up to 10 000 objects can be displayed in this menu, but only a limited amount of cells can be displayed.

If all your objects only have one property you might be able to display 10 000 but if they have many properties you will soon find yourself closer to the limit of what the browser can handle.

You can see how many objects are selected below the QTO list.
