C.2.77 4D CAD 1.0d14

• (177) Fixed a bug where (e.g.) rotating objects within the block of a selected insert object didn’t redraw the selection bounds.
  
  
• (178) Fixed known problem: drawing-order of copied layers.
  
  
• (179) Fixed problem where CADCopyTo and CADMoveTo caused a wrong drawing order.
  
  
• (180) Fixed documentation: CADScaleXY is a function, not a procedure.
  
  
• (181) Warning. The syntax of the following methods has changed: CADPointOnLine , CADPointInRect , CADRectAndRect , CADLineAndRect and CADLineAndLine .
  
  
• (182) CADOffscreen and CADEndOffscreen are new.
  
  
• (183) CADGetKeyMask and CADSetKeyMask are new.

  Note. CADClear doesn’t clear key masks.
  
  

• (184) CADCopyLayers , CADCopyAttributes and CADCopyBlocks are new.
  • Before copying, these methods check for identical copies in the target area.
  • Attributes copied include linetypes, markings and (in a future release) hatches. Standard attributes are not copied (as they are pre-installed in any area).
  • Copied target layers inherit source layer settings. Settings of identical (uncopied) target layers are not changed.
  • It is an error if source and target area are the same.
  • If the ID-order of copied layers, sublayers and attributes is important, call CADCopyLayers and CADCopyAttributes before calling CADCopyBlocks .

  
  
  

• (185) CADCopyPrefs is new (but still unimplemented)
  • If the target area root block is empty, CADCopyPrefs sets the draw size also.
  • It is an error if source and target area are the same.

  
  
  

• (186) CADCopyArea is new (but still unimplemented)
  • The target area is cleared, then everything is copied: layers, sublayers, attributes, blocks, objects, preferences and draw size.
  • It is an error if source and target area are the same.

  
  
  

• (187) CADCopyObjTo and CADCopyObjByMatrix are new.

  Note. These methods are essentially the same as CADCopyTo and CADCopyByMatrix respectively, except that:

  • the source scope must be an object ID;
  • the object ID of the resulting object is returned (so there is no need to create a target scope).

  
  
  

• (188) CADDuplicate has disappeared. It can be implemented with other copy calls.
  
  
• (189) CADStretchObj returned kCADCannotStretchObj for objects without a direction vector (e.g. most polylines and inserts of empty blocks). CADStretchObj now stretches these objects along the X- and Y-axes.
  
  
• (190) CADStretchObj returned kCADBadParam if the top/bottom stretchfactor was not applicable and it had a value other than 1.0 or 0.0. CADStretchObj now ignores non-applicable top/bottom stretchfactors. This is true for line objects, polyline objects with two vertices and indexed lines of polyline objects
