| − | == Introduction ==
| + | |
| − | Alignment Tool is available in the Papyrus toolbar:<br/>
| + | |
| − | [[File:Alignment_Toolbar.JPG]]<br/>
| + | |
| − | 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:<br/>
| + | |
| − | {|style="margin: auto;"
| + | |
| − | |[[File:normal_Align_selection.JPG|frame|Normal Selection]]
| + | |
| − | |[[File:Reference_Align_selection.JPG|frame|Primary Selection]]
| + | |
| − | |}
| + | |
| − | <br/>
| + | |
| − | To implement Alignment, some rules have been defined.
| + | |
| | | | |
| − | == General Rules ==
| + | [[Category:Papyrus]] |
| − | [[File:Alignment_Toolbar.JPG|frame|Alignment Types]] | + | |
| − | The Alignment Tools allows 6 types of alignment:
| + | |
| − | *Horizontally
| + | |
| − | **Left
| + | |
| − | **Center
| + | |
| − | **Right
| + | |
| − | *Vertically
| + | |
| − | **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:
| + | |
| − | #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. <br/>
| + | |
| − | === General Case ===
| + | |
| − | Basically, alignment is used in order to make the model easier to be read and more aesthetical.
| + | |
| − | To align objects:
| + | |
| − | :* Select the object to be aligned
| + | |
| − | :* Click on the align tool button [[File:Align_button.JPG]]
| + | |
| − | :* Choose the proper type of alignment
| + | |
| − | <br/>
| + | |
| − | #Example A: Standard alignment
| + | |
| − | #:[[File:General_Align1_before.JPG]]
| + | |
| − | #:[[File:General_Align1_after.JPG]]
| + | |
| − | #:In this case the reference object is the right one. <br/>
| + | |
| − | #Example B: Parent alignment
| + | |
| − | #:In this second example, the object (the Class ) is aligned on his parent (the Package), the unauthorized alignment appears disable (in grey)
| + | |
| − | #:[[File:General_Align2_before.JPG]]
| + | |
| − | #:[[File:General_Align2_after.JPG]]
| + | |
| − | | + | |
| − | === Hierarchy ===
| + | |
| − | In this section, some examples of alignment in case of hierarchy between objects (parent / children).
| + | |
| − | #Example A: Only the parent is aligned
| + | |
| − | #:[[File:Hierarchy_Align1_before.JPG]]
| + | |
| − | #:As shown in the result screenshot below , only the parent (the Package) has been aligned.
| + | |
| − | #:[[File:Hierarchy_Align1_after.JPG]]
| + | |
| − | #Example B: Alignment inside the Container bounds is available
| + | |
| − | #:[[File:Hierarchy_Align2_before.JPG]]
| + | |
| − | #:In the align options list, only the ones that keep the objects inside his container are enable.
| + | |
| − | #:[[File:Hierarchy_Align2_after.JPG]]
| + | |
| − | | + | |
| − | === Labels ===
| + | |
| − | In this section, some examples of labels alignments.
| + | |
| − | #Example A: Standard label alignment
| + | |
| − | #:[[File:Label_Align1_before.JPG]]
| + | |
| − | #:[[File:Label_Align1_after.JPG]]
| + | |
| − | #Example B: Dependency with another selected object
| + | |
| − | #:[[File:Label_Align2_before.JPG]]
| + | |
| − | #:As shown in the result screenshot below, only the class is aligned. The label moves according to the connection move.
| + | |
| − | #:[[File:Label_Align2_after.JPG]]
| + | |
| − | | + | |
| − | === Edges ===
| + | |
| − | 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
| + | |
| − | :[[File:Link_Align1_before.JPG]]
| + | |
| − | The extremities are alignment in order to have an horizontal connection. The connection handles remained at the same place on the object
| + | |
| − | :[[File:Link_Align1_after.JPG]]
| + | |
| − | | + | |
| − | == Limitation ==
| + | |
| − | This section will describe some limitations of the alignment tool.
| + | |
| − | === Hierarchy ===
| + | |
| − | A parent cannot be aligned on one of his child:
| + | |
| − | [[File:Hierarchy_Align3_limitation.JPG]]
| + | |
| − | === Label ===
| + | |
| − | The extremities (source or target )of a connection cannot be aligned on any Labels of this connection.
| + | |
| − | [[File:Label_Align3_limitation.JPG]]
| + | |
| − | === Edge ===
| + | |
| − | 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.
