## 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.

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.
