# Support for multi-page documents in ABBYY FlexiLayout Studio

> Multi-page sheets merge document pages into one coordinate space. Learn how global and local coordinates work and which elements span multiple pages.

ABBYY FlexiLayout Studio merges the pages of a multi-page document into a single coordinate space. Understanding how these coordinates work helps you set relations between elements that span several pages.

## Multi-page sheet and coordinates

The set of all the pages of a document is termed a multi-page sheet. A multi-page sheet is obtained by merging the pages of the document top down, without any joints or gaps.

The left edges of all the pages are placed on the same axis, which goes through the point `(0,0)`. The sequence of the pages in the sheet depends on their order in the batch.

Two coordinate systems are used: global (spanning the entire document) and local (bound to a particular page). The only difference between them is that the global system has parallel shifts, with each page having its own shift.

For example, suppose a document has three pages of the following sizes: `2500x3500`, `2400x3400`, and `2300x3300`. The global coordinates of the pages are then `[0, 0, 2500, 3500]`, `[0, 3500, 2400, 6900]`, and `[0, 6900, 2300, 10200]` (in the order `[left, top, right, bottom]`).

For relations between elements, the global coordinate system is used, so that relations such as `BELOW` are interpreted correctly.

## Multi-page hypotheses

Hypotheses for the following elements may be located on multiple pages:

* **Group**
* **Repeating Group**
* **Table**
* **Region**
* **Object Collection**

**Region** and **Object Collection** elements contain all the appropriate objects within the search area.
