Double lines resymbolization in the drawing is called widgets. OpenBuildings Designer supports two types of widgets

• Graphical Widgets:-To generate Graphical Widgets, uncheck "Generate Movable Widgets" checkbox from the Reference Presentation dialog, Building Panel Structural tab.

  The graphic symbol can be either a graphical representation such as a double line resymbolization or a cell chosen to represent the top or side of a Structural element.

  You cannot change the position of the Graphical Widgets in drawing once the drawing is created.

  
• Movable Widgets:-Movable Widgets get generated in the drawing if "Generate Movable Widgets" checkbox is toggled ON from the Reference Presentation dialog, Building Panel Structural tab.

  As the name suggests, these double lines can be moved along a member line just as a label can be moved to make the drawing easier to read. Moving a graphic symbol in a drawing may be helpful to you if it appears in an awkward place in your drawing.

  
  
  Note: To generate Movable Widgets by default, toggle ON "Generate Movable Widgets" checkbox in the drawing seed file, and then create the drawing using that seed file.

Configuration variable BB_CREATE_STRUCTURAL_WIDGET_ANNOTATIONS cab also be used to control Movable Widgets .The behavior of this configuration variable is similar to the BB_AUTOANNOTATION.

• If Set BB_CREATE_STRUCTURAL_WIDGET_ANNOTATIONS = '1', 'true' or 'on

  It always generates Movable Widgets. UI setting is always "Checked" and disabled. A flyover hint explains the reason.

  
• If Set BB_CREATE_STRUCTURAL_WIDGET_ANNOTATIONS = '0', 'false' or 'off

  It always generates Graphical Widgets. UI setting is always "Unchecked" and disabled. A flyover hint explains the reason.

  
• If Set BB_CREATE_STRUCTURAL_WIDGET_ANNOTATIONS = Undefined (or any other value)

  Generation of movable widgets is controlled via UI setting on Structural tab from Reference Presentation dialog. The UI setting for Movable Widgets is described above.
