Layer Options
- Assignment Policy—Assigns the entities of a model to separate layers. Choose one of
the following styles:
Optimal (default)—Assigns layers in such a way that the overall sum of the layer distances of all relationships in the layout is minimal.
Tight Tree Heuristic—Approximates the layering done by Hierarchical-Optimal.
BFS Layering (breadth-first search) (default)—Results in all relationships spanning at most one layer in the resulting drawing. Edges between entities that belong to the same layer are possible.
From Sketch—Tries to find a layering that is similar to the one in the input model. When this layering strategy is used, the layout algorithm may place entities in the same layer, even though they are connected by a relationship. These inner layer relationships are always routed in an orthogonal style.
Topmost—Assigns all entities without incoming relationships (in degree zero) to the topmost layer of the layout. The number of separate layers will be as small as possible.
- Scale(From Sketch assignment policies only)—Sets the size of the halo around an entity or the respective insets that are used to calculate layer overlaps.
- Halo(From Sketch assignment policies only)—Sets the scale of an entity's height.
- Minimum size—(From Sketch assignment policies only) Allows a group entity to accommodate the size of its label, provided it meets minimum size standards.
- Maximum size—(From Sketch assignment policies only) Allows a group entity to accommodate the size of its label, provided it meets maximum size standards.
- Alignment within layer—Determines how to align the entities within the layer. Choose
one of the following styles:
Top of Entities —Aligns the layer's entities along the top.
Center of Entities —Aligns the layer's entities along the center.
Bottom of Entities (default)—Aligns the layer's entities along the bottom.
