====== Grids ======

**Patterns** allow coloured areas to be added in the background
of the Time-Location schedule.

They are used to highlight specific periods or areas of the project
in order to improve the readability of the schedule.

Patterns can be applied:

  * **in time**
  * **in space (distance)**

-----

===== Time patterns =====

**Time patterns** highlight specific periods in the schedule.

They are commonly used to display:

  * weekends
  * non-working periods
  * specific calendar periods
  * regular time cycles

Two configuration modes are available.

-----

==== Interval pattern ====

This mode creates a repeated pattern based on a
**regular time interval**.

For example:

  * every week
  * every month
  * every day

{{:en:time_distance:2026-03-12_21h42_23.png?600|}}

The main parameters are:

  * **Pattern colour**
  * **Interval** (e.g. every week)
  * **Snap to patterns**
  * **Pattern scope** (distance or entire period)

This mode is particularly useful for representing
regular time cycles.

-----

==== Calendar-based pattern ====

It is also possible to create patterns based on
the **calendar settings**.

{{:en:time_distance:2026-03-12_21h43_32.png?600|}}

This mode can be used, for example, to display:

  * **working periods**
  * **non-working periods**
  * **weekends**

These patterns make the schedule easier to read
by highlighting working and non-working periods.

-----

===== Distance patterns =====

**Distance patterns** allow coloured areas to be added
along the geographical axis of the project.

{{:en:time_distance:2026-03-12_21h45_49.png?400|}}

Three types of patterns can be used.

-----

==== Interval pattern ====

This mode creates a repeated pattern based on a
**regular distance interval**.

For example:

  * every kilometre
  * every 500 metres

{{:en:time_distance:2026-03-12_21h46_59.png?400|}}

The main parameters are:

  * **pattern colour**
  * **interval**
  * **marker origin**

This mode is useful for creating regular visual
references along the project.

-----

==== Rectangular pattern ====

The rectangular pattern allows you to define
**a rectangular area manually** within the schedule.

{{:en:time_distance:2026-03-12_21h48_58.png?400|}}

This area is defined by:

  * a **start chainage**
  * an **end chainage**
  * a **start date**
  * an **end date**

This type of pattern is particularly useful to:

  * represent a **work zone**
  * identify a **construction phase**
  * highlight a **sensitive project area**

-----

==== Sector-based pattern ====

Patterns can also be created using the
**project sectors**.

{{:en:time_distance:2026-03-12_21h49_55.png?400|}}

Patterns can then be applied directly to:

  * sections
  * structures
  * work areas
  * key points

This allows specific parts of the project
to be quickly visualised in the Time-Location schedule.

-----

===== Pattern priority =====

When several patterns are active,
their priority can be defined using the options:

  * **Time**
  * **Distance**

This priority determines which pattern
is displayed first when they overlap.
