    Block Class
    In This Topic
    A block object in P8 is a special kind of group which combines graphical placements (e.g. lines, circles, etc.) and, optionally, one symbol reference. Such group is placed on a page and is referenced by a block reference object. In case a new block is created and it contains the symbol reference in itself, this symbol reference is also the block's reference (i.e. no extra block reference object is created). This Block class represents both the block itself as well as the block reference.

    public class Block : Placement 
    public ref class Block : public Placement 
    * Only one SymbolReference object can be included in a block. * A block may include another block's reference.
    Public Constructors
    Public ConstructorDefault constructor. Creates invalid Block object.  
    Public Properties
    Public PropertyNumber of objects in the block.  
    Public PropertyReturns an array of objects cross-referenced with this object (i.e. having the same name - in case of functions - or otherwise associated) (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyReturns the project as number. The number is unique for all open projects in one session. The number changes when the project is closed and opened again. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertySets display sequence. The drawing order flag will be used to sort elements according to drawing order within a group. If elements chare the same value the drawing order will result from order of the data model. Default value is 67. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public PropertyReturns a group that the Placement object belongs to. If the Placement object doesn't belong to any group, NULL is returned. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public Property

    Determines if the the StorableObject is locked.

    The StorableObject is locked when it was explicitly or implicitly locked.

    (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyReturns true if the placement is placed (Inherited from Eplan.EplApi.DataModel.Placement)
    Public PropertyDetermines if StorableObject is read-only (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyGets/Sets visibility of the object as set in its properties dialog. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public Property

    Determines if the the StorableObject is transient.

    The StorableObject is transient when it was created by default constructor and:

    it is a Page and it was not assigned a Project,

    it is a Placement or any class derived from it and was not assigned a Page.

    (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyDetermines if StorableObject is correct database object and is not deleted. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyOverridden. Get or set the placement's location.  
    Public PropertyName of the referenced block.  
    Public PropertyReturns the object identifier as number. The number is unique for all objects of this type. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyReturns the page the Placement is on, or assigns a Page object to the placement. If the placement was previously assigned to another page, it is removed from old one and assigned to the page given as an argument. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public PropertyReturns the project the StorableObject belongs to. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyEPLAN properties of the block reference object.  
    Public PropertyNumber of references.  
    Public PropertyReturns array of placements combined in this block.  
    Public PropertyReturns the type of the object as number. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public Methods
    Public MethodOverloaded. Breaks up the block into its individual elements, also recursively.  
    Public MethodOverloaded. Copy Placement and insert the Copy into destination group. Copied placement will be inserted into desired project of destination group. If this placement is temporary, the copy will be persistent, if the destination group is also persistent. Group or Page, where the placement will be inserted. Defines whether a layer should be matched by name. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public MethodCreates valid Block object from the passed elements. At least two elements must be passed in arrPlacements.  
    Public MethodNon-deterministic Finalizer of Block object. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public MethodOperator of comparison implementation. Checks if two StorableObjects refer to the same object in the project. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public MethodPlacement bounding box. Bounding box is a rectangle which contain this placement. It can be also used to determine placement size. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public MethodServes as the default hash function. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public MethodReturns object type name. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public MethodTries to lock current object in database for exclusive access. Throws Eplan.EplApi.Base.LockingException on failure. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public MethodRemoves placement. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public MethodOverloaded. Scales the placement (or group of placements) by the specified factors in X and Y axis with scaling origin point specified by the ptOrigin parameter X axis factor. E.g. value of 2 makes the width two times bigger.Y axis factor. E.g. value of 0.5 makes the height two times smaller.Scaling origin point. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public MethodTries to lock current object. If object is Placement - it's page will be locked as well; Eplan.EplApi.DataModel.E3D.Placement3D locks it's installation space; Function locks all it's connections and connection definition points; Page locks all placements from this page. Throws Eplan.EplApi.Base.LockingException on failure. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public MethodReturns this object as string identifier. (Inherited from Eplan.EplApi.DataModel.StorableObject)
