Namespace:  Tekla.Structures.Drawing
Assembly:  Tekla.Structures.Drawing (in Tekla.Structures.Drawing.dll) Version: 2019.0.0.0 (2019.0.0.0)
public sealed class PlacingAttributes : GenericAttributesBase, 

The PlacingAttributes type exposes the following members.

  Name Description
Public method PlacingAttributes
Creates a new placing attributes instance. The default parameters are: IsFixed = true, default PlacingDistanceAttributes, default PlacingQuarterAttributes.
Public method PlacingAttributes(Boolean, PlacingDistanceAttributes, PlacingQuarterAttributes)
Creates a new placing quarter attributes instance with the given parameters.
  Name Description
Public property IsFixed
Defines whether the object is using fixed or free placing. If set to true, it means that fixed placing is enabled, and the object will not be rearranged in the drawing automatically. If set to false, then free placing is enabled, and the object will be placed in the most appropriate location near the original location.
Public property PlacingDistance
Gets or sets the placing distance attributes.
Public property PlacingQuarter
Gets or sets the placing quarter attributes.
  Name Description
Public method Clone
Creates a new object that is a copy of the current instance.
Public method IsEqual
Compares the current object with an object of the same type.
(Overrides GenericAttributesBaseIsEqual(Object).)
The following example enumerates through all marks in all views and changes their PlacingAttributes and InsertionPoints. You may try commenting out either Modify part to see how it affects the end result.

                        // however, if there's already an object there, it will find a new place around that area.
                        // When finding a place around the area, the rest of the PlacingAttributes take effect.
                        MyMarkBase.Attributes.PlacingAttributes.IsFixed = false;
                        // Minimum distance from other objects when searching for a space to place the mark

                        // The directions to look for possible places
