C.2.36 4D CAD 1.1.7 d4

• (472) Solved a printing problem on Macintosh with large high-resolution prints.
  
  
• (473) CAD constants are auto-defined as 4D constants.
  
  
• (474) On MacOSX, CADImportImage can get a raster image from (the first page of) a PDF file.
  
  
• (475) Parameter theMeasurePaneFlag of CADSetDisplay has been implemented. CAD features a measure pane.
  
  
• (476) Entering values in a measure pane edit box doesn’t generate kCADEventIDKeyDown or kCADEventIDAutoKeyDown keyboard events.

  Accepting (concluding) a measure pane edit box value generates one of three possible events:

  • kCADEventIDObjTranslate . Be aware that the (values of the) event parameter TranslationByKeyFlag have changed.

    Measure pane translate-actions can be undone by both the user and the application programmer (kCADUndoTranslateByMeasurePane ).

  • kCADEventIDObjRotate . This is a new event.

    Measure pane rotate-actions can be undone by both the user and the application programmer (kCADUndoRotateObjByMeasurePane ).

    Please note that rotatating objects by clicking on the "button tool palette" still generates a kCADEventIDCommand event (but this may change in the future).

  • kCADEventIDChangeOfMeasure . This is a new event.

    Measure pane measure-changes can not (yet) be undone.

  
  
  

• (477) Measure pane implementation notes:
  • Polylines don’t have a rotation value (yet).
  • Raster images and block inserts don’t have a rotation value, if their insertion matrix is non-rectangular.
  • If the linelength "L" subpane is visible, length and width of lines are xy-oriented. If the linelength "L" subpane is invisible, length is the line-length (and there is no width)
  • Strings don’t have a height value in the measure pane.
  • Changing the length of squares, circles and circle-arcs also changes the width (and vice versa).
  • For circle-arcs and ellipse-arcs, length and width stand for radiusx and radiusy.
  • Pressing ESC cancels editing a measure pane value.
  • Pressing Return, Up Arrow, Down Arrow, Tab or Shift-Tab accepts a measure pane edit box value (if possible).
  • A mouse click in the CAD area accepts a measure pane edit box value (if possible), except if the click is in the measure pane area outside another measure pane box.
  • A mouse click in a menu or in a 4D enterable field, variable or area accepts a measure pane edit box value (if possible) or cancels it (if the string entered in the edit box doesn’t describe a floating point number).
  • The following commands automatically cancel a measure pane edit box value:

    CADClear , CADImportDXF , CADCancelDXF , CADAcceptDXF , CADLoadFromFile , CADLoadFromPict , CADCommand ( kCADCommandEditClear ).

  • The following commands automatically accept a measure pane edit box value (if possible) or cancel it (if the string entered in the edit box doesn’t describe a floating point number):

    CADPageSetup , CADPrint , CADSetMode ( kCADModePrintingPreview ), CADSetDisplay , CADSetMeasurePrefs .

  • Rotating objects (currently) uses the object’s rotation point, not the anchor value preset in the measure pane.
  • The values in the measure pane for perimeter and surface-area are additive and non-editable.
  • The values in the measure pane for X and Y are non-editable. In translate mode, XY is the "hotpoint" (the target point for snaps). In reshape mode, XY is the dragged grip coordinate. In draw modes, XY is the cursor coordinate (or its snap).
  • Entering a negative value in the measure panes for length, width, length-difference, width-difference, linelength or linelength-difference can cause selected objects to be mirrored (flipped).
  • When a measure pane value is applied to selected objects, objects with a relevant lock are automatically skipped (without an error message).
  • The mirror lock is currently ignored (this is a bug).
  • The measure pane uses the decimal-point character that the user has set in system software preferences.
