C.2.80 4D CAD 1.0d11

• (147) CADZoom could return error kCADImplementationRestriction . This was caused by a 4D problem that has been worked around.
  
  
• (148) CADSetLayerOrder did nothing. This has been fixed.
  
  
• (149) Fixed theIdenticalFlag parameter of CADColorToIndex and CADColorToDXF (it compared 48-bit RGB-color values rather than 24-bit CAD-color values).
  
  
• (150) CADObjEllipse swapped CenterX and CenterY parameters. This has been fixed.
  
  
• (151) CADSelect created unordered scopes. This has been fixed.
  
  
• (152) Warning. The parameters of CADPrint have changed. CADPrint now prints selected objects if any object is selected. If no objects are selected, all objects are printed. A printing clip box may still restrict which objects are actually printed.
  
  
• (153) Warning. The parameters of CADGetPrintSpecs and CADSetPrintSpecs have changed. Rotation of the printout can be specified and precision adjustment factors in X and Y directions.

  Note. The adjustment factors are paper-oriented (applied after printout rotation and/or landscape rotation).
  
  

• (154) Warning. CADBounds has changed. A new parameter indicates what bounds to get: logical-bounds (as before), physical-bounds, draw-bounds, or align-bounds.

  The draw-bounds of an object is equal to the physical bounds, except that

  • draw-bounds of circular and elliptical arcs include the arc’s center;
  • draw-bounds of inserts include their logical bounds;
  • draw-bounds of inserts include the bounds of the transformed draw-bounds of the block (which is relevant for inserts with non-right-angular rotations);
  • an empty polyline (not allowed) has draw-bounds (0.0, 0.0, 0.0, 0.0);
  • an insert of an empty block has draw-bounds (x, y, x, y) where (x, y) is the insertion point.
  • an empty drawing has draw-bounds (0.0, 0.0, 0.0, 0.0).

  This is because

  • when an arc is selected, the center of the arc is drawn;
  • when an insert is selected, the logical bounds of the insert is drawn.

  The align-bounds of an object is the same as the logical bounds, except that

  • the yLo and yHi parameters of the align bounds of a string-object are the y-value of the base-point of the string-object (even if rotated).

  Thus, strings align on their base-line (or point). Note that the align-bounds of an insert is identical to its logical-bounds (whether the insert’s block contains strings or not).
  
  

• (155) Warning. CADAlign has changed. A parameter specifies what bounds to align on.
  
  
• (156) Warning. The parameters of CADGetMatSpecs have changed.
  
  
• (157) New are calls to get and set the "angle" of polyline objects. This is an application specific field (unaltered by any transformation).

  Note. In a next version, these calls might be replaced by a polyline rotation field.
  
  

• (158) CADSetPrintClip is more strict. When clipping, the clipping box should intersect the drawing bounds (with a non-zero width and height).
  
  
• (159) The printing-clip mode is fully functional.
  
  
• (160) The printing-preview mode is fully functional.
  
  
• (161) The enclose-mode is functional. The enclose-method of CADSelect is functional.

  Note. Enclosing strings and rotated strings isn’t smooth. It means enclosing the string’s logical box.
  
  

• (162) Fillcolors that are the same as the background color aren’t inverted anymore.
  
  
• (163) Printing is fully functional for Macintosh.
  
  
• (164) CADBlendColor is new.
  
  
• (165) To do. Drawing error: insert objects are always on top of a layer.
  
  
• (166) To do. Fix CADZoom in preview mode. Save and restore zoom state of preview mode.
