Alignment Tool

Introduction

Alignment Tool is availbale in the Papyrus toolbar:

Alignment allows to align the different objects of the model based on a reference object. The reference object is basically the last object selected (primary selection) and can be identified with the handles color:

Normal Selection

Primary Selection

To implement Alignment, some rules have been defined.

General Rules

Alignement Types

The Alignment Tools allows 6 types of alignmeent:

• Horizontaly
  • Left
  • Center
  • Right
• Verticaly
  • Top
  • Middle
  • Bottom

These types can be disable if the alignment is not possible. Here is the different rules on which the alignment is based:

1. The alignment is available only if the selected object can be moved on the reference
2. When an object and one or several children should be aligned on a third object, only the parent is aligned
3. An object can only be aligned inside of its container's bounds.(In order to avoid scrollbar and invisible objects)
4. An object cannot be aligned on one of its children.

Using of Alignment Tool

Here under, some examples of using of alignment tool.

General Case

Basically, alignment is used in order to make the model easier to be read and more aesthetical. To align objects:

1. Select the object to be aligned
2. Clic on the align tool button
3. Choose the proper type of alignment

The refrence object is here the right one.

In this second example, the object (the Class ) is aligned on his parent (the Package): The unauthorized alignment appears disable (in grey)

Hierarchy

In this section, some examples of alignment in case of hierarchy between objects (parent / children).

1. Example A: Only the parent is aligned

As shown in the result screenshot below , only the parent (the Package) has been aligned.

1. Example B: Alignment inside the Container bounds is available

In the align options list, only the ones that keep the objects inside his container are enable.
