Condition Editor Dialog

Used to create conditions for display rules.

You can access this dialog from the following:

Display Rules dialog: click the Condition cell in the list box

Setting	Description
Description	Adds description to the condition. This description displays in the Condition cell in the Display Rules dialog's list box. By default, the description is the condition that you set. You can overwrite the default description.
Add new criterion	Creates a new criterion. You can select a property from the property picker next to the icon. Clicking the drop-down list opens the following host property types: Dgn Elements - Contains properties of elements or associated items such as element color, area, thickness, and so on. File - Contains file or associated item properties such as file name, file size, revision number, and so on. Models - Contains model or associated item properties such as model name, description, annotation scale, and so on. View - Contains properties of the view or associated items such as display style, camera position, view index, and so on. Item Types - (Available when Item Types are available in the DGN) Contains item types and associated properties of item types. References - (Available when references are attached to the DGN) Contains reference or associated item properties such as reference attachment file name, model name, level, and so on. Each host property type contains one or more types. These types depend on the content of file. For example, if your file contains design, drawing, and sheet models, the Model host property type lists all three model types. If your file contains only design models, the Model host property type lists only the design model. Expanding each type lists different categories of properties. Further expanding the categories, you get the list of properties. You can also search for a particular property using the Search field. Some properties called, struct properties contain nested properties. Such properties can be expanded to select the nested properties. Each type inside a host property type contains two special properties, namely, `Is Type` and `Is Not Type`. These properties define the condition whether the selected type is available or not available respectively. Depending on the property selected, additional drop-downs may be displayed for selecting comparison operators and setting the values or properties. For example, if you select the level property of an element, you will get two drop-down options. One will list the comparison operators and the other will list all the levels. The comparison operator drop-down list has following special options: `Is Set`, and `Is Not Set` - These create a condition to check if the selected property is set or not set respectively. `Resolves To` and `Does Not Resolve To` - These options are available for the Color, Line Style, and Line Weight host properties. If you select one of these comparison operators, the level symbology of the element is compared with the value defined in the condition. For example, say you select the host property `ELEMENT.Elements.Color`, set the comparison operator to `Resolves To`, and set the color value to "1". Now if an element’s color is set to ByLevel, then the Condition Editor will check the level associated with the element and compare the level color with color "1". If the level color resolves to color "1", the element will pass this criterion. You can now use Wilds Cards in Display Rules by setting the "like" comparison followed by (*/?) to filter out properties from exhaustive lists and search the exact string.
Show classes for available elements	Lists all available classes. The following options are available in the drop-down: Show classes for available elements Show classes for selected element Note: You must select an element(s) prior to opening Condition Editor to use this option. If there is no element selected, you will be alerted by a message. Show all schema - shows all available classes in MicroStation.
Search	Lets you search for properties or classes by name.
Toggle between value and property comparison	Lets you add additional criteria to compare with a property or a value. You can click on this icon to switch between value and property to compare.
Select multiple criteria to group	(Available only when you have three or more criteria in a condition) Allows you to select more than one criterion for grouping.
Group selected criteria	(Available only when you select two or more Select multiple criteria to group check boxes) Groups the selected criteria. For more details, see Criteria based grouping.
Delete criteria	Deletes the criteria.

Examples of Conditions for Display Rules

You want to identify all the elements that are of type "Room".
ELEMENT Is Room

Where,

ELEMENT - is the type of data or context object, such as element, model, file, or reference.

Is Room - is the property that identify whether the element is of type Room.
You want to identify all the shapes in your model that have an area greater than 20 square meters. To achieve this, you can create the following condition in the Condition Editor dialog:
ELEMENT.Shapes.Area > 20.000M2

Where,

ELEMENT - is the type of data or context object, such as element, model, file, or reference.

Shapes.Area - is the name of the property whose value is the area of the element.

> - Comparison operator. You can also use =, <, >, <=, >=.

20.000M2 - is the value against which the property will be compared.
You want to identify all the shapes in your model greater than 20 square meters and are also occupied. To achieve this, you will have to create two criteria in the condition, as shown below.
ELEMENT.Shapes.Area > 20.000M2

AND ELEMENT.Room.Occupied = Yes

Where,

ELEMENT - is the type of data or context object, such as element, model, file, or reference.

Shapes.Area - is the name of the property whose value is the area of the element.

> - Comparison operator. You can also use =, <, >, <=, >=.

20.000M2 - is the value against which the property will be compared.

AND - is the logical AND operator.

Room.Occupied - is the name of the property which gives the status whether the room is occupied.

Yes - is the value of the Room.Occupied property.
You want to identify the following:
1. all shapes on floor 1 that have an area greater than 20 square meters and
2. all shapes on floor 2 that have an area greater than 30 square meters
To achieve the above to criteria, you can use criteria grouping and create the following condition in Condition Editor dialog:

(

ELEMENT.Room.In floor = "1"

AND ELEMENT.Shapes.Area > 20.000SQ.M)

)

OR

(

ELEMENT.Room.In floor = "2"

AND ELEMENT.Shapes.Area > 30.000SQ.M

)

Where,

( ) - the parenthesis indicate criteria grouping.

ELEMENT - is the type of data or context object, such as element, model, file, or reference.

Room.In floor - is the name of the property whose value is the floor number of the element.

= - Comparison operator. You can also use =, <, >, <=, >=.

1 and 2 - values against which the properties will be compared.

AND and OR - is the logical AND operator.

Shapes.Area - is the name of the property whose value is the area of the element.

20.000M2 and 30.000M2 - values against which the properties will be compared.
You have an item type that identifies small rooms and is associated with your file, model, reference, or view. You want to create a condition that compares the value of this item type with the area of your rooms.
To achieve this, you can create the following condition:

ELEMENT.Shapes.Area <= MODEL.RoomThresholds.SmallRoomSize

Where,

ELEMENT - is the type of data or context object, such as element, model, file, or reference.

Shapes.Area - is the name of the property whose value is the area of the element.

<= - Comparison operator. You can also use =, <, >, >=.

MODEL - is the type of data or context object, such as element, model, file, or reference.

RoomThreshold - is the name of the item type.

SmallRoomSize - is the name of the property definition in the item type.
