Papyrus User Guide/Toolbars/Alignment
Alignment Tool is available 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:
To implement Alignment, some rules have been defined.
The Alignment Tools allows 6 types of alignment:
These types can be disable if the alignment is not possible. Here is the different rules on which the alignment is based:
- The alignment is available only if the selected object can be moved on the reference
- When an object and one or several children should be aligned on a third object, only the parent is aligned
- An object can only be aligned inside of its container's bounds.(In order to avoid scrollbar and invisible objects)
- An object cannot be aligned on one of its children.
Using of Alignment Tool
Here under, some examples of using of alignment tool.
Basically, alignment is used in order to make the model easier to be read and more aesthetical. To align objects:
- Example A: Standard alignment
- Example B: Parent alignment
In this section, some examples of alignment in case of hierarchy between objects (parent / children).
- Example A: Only the parent is aligned
- Example B: Alignment inside the Container bounds is available
In this section, some examples of labels alignments.
- Example A: Standard label alignment
- Example B: Dependency with another selected object
Edges alignment could sound not realistic. Actually, edge alignment is an alignment between the extremities of the edge, to make the edge horizontal or vertical. Example: Standard edge alignment
The extremities are alignment in order to have an horizontal connection. The connection handles remained at the same place on the object
This section will describe some limitations of the alignment tool.
To make the edge alignment available, the edge handles should correspond to the same direction (horizontal or vertical). In the following case, source handle is on TOP and target handle is on LEFT. it is then impossible to align the edge.
