# Bill of Quantities ## Copying Elements & Collections It is currently possible to copy single-material individual elements of an EC3 project to a different EC3 project. Also, it’s possible to copy collections this way. But copying multi-material elements in such fashion is not yet supported, you can only copy those inside a particular EC3 project. To copy an element between EC3 projects, you can do the following. 1. Open an EC3 project. 2. Right-click a single-material element or sub-element and choose Copy Element.

3. Staying in the same browser tab (this is important), switch to Plan & Compare Buildings > My buildings

4. In the project list, click another EC3 project. 5. Right-click a label and select Insert Copied Element. ## Selecting visible columns The bill of quantities table starts with a set of columns capturing the most useful data. You can reveal additional columns and customize your table using the table icon in the top right corner of the table.
