C.2.69 4D CAD 1.0d22

(267) Documentation for kCADEventIDKeyDown and kCADEventIDAutoKeyDown events was wrong (there is an After phase, not a Before phase).
(268) Rotating a square or rectangle object right-angular could change the box instead of the object’s rotation. This has been fixed.
(269) CADGetEllipse swapped CenterX and CenterY parameters. This has been fixed (cf. note 150).
(270) Selecting circle arcs and ellipse arcs in rotated block inserts wasn’t always correct. This has been fixed.
(271) Using the command key modifier while reshaping an object deselected the object. This has been solved as follows:
- the command key is a reshape modifier if the mouse click is on an object grip;
- the command key is a deselect modifier if the mouse click is on an object but not on an object grip;
- the command key is a translate modifier if the mouse click is not on an object.
(272) Solved problem of strings displayed in block inserts stretched in one direction (cf. note 230).
(273) Implementation note − CADGetZoom returns 0.0 for theZoomUnitsPerPixel, theZoomFactor, theZoomMaxFactor and theZoomMinFactor in the following cases:
- for offscreen areas
- for the clipboard area
- in the Before phase of layout areas.
The reason is, there is no (known) on-screen size. In this situation, CADGetZoom returns theZoomLoX, theZoomLoY, theZoomHiX, theZoomHiY as set by the last CADZoom call.
(274) Locking of user interface attributes of objects has been implemented.
- The (sub)scope of unlocked selected objects is passed in EventData parameters for the kCADEventIDEditCut , kCADEventIDEditClear , kCADEventIDObjTranslate and kCADEventIDCommand events.
- Trying to reshape a (completely) locked object doesn’t initiate an event.
- CADCommand skips objects that are locked (on the command’s action).
- CADCommand currently initiates no events.
- The locking parameter of API calls is unimplemented. Pass kCADLockingIgnoreLock .
- The Cut item in the Edit menu is enabled if objects are selected, even if all those objects are locked (kCADObjLockCutAndRemove ).
(275) Selection by line has been implemented.
(276) Object scope kCADScopeSelectedObjects can be passed to CADEmptyScope .
(277) CADGetScopes has been renamed CADGetScopeIDs .
(278) Optionally a target scope can be passed to CADLengthenObj . If so, CADLengthenObj doesn’t return error kCADCannotLengthenObj , but passes objects that cannot be lengthened in the target scope. Source and target scope can be the same.
There is another new parameter: no objects are actually lengthened if theOptionalCheckOnlyFlag is set.
(279) CADFindByKey is new. Source and target scope can be the same.
(280) CADMetricsArray has been renamed CADMetrics .
(281) CADMetricsByMatrix is new.
(282) CADPolyBounds is new.
(283) CADStringBounds is new.
(284) CADLineAndArc is new. It can be used to calculate the intersection between a line and the frame (but not the fill) of a circle, circle-arc, ellipse or ellipse-arc.
(285) Translating (unlocked) objects with arrow keys is implemented. This generates a kCADEventIDObjTranslate event. The translation offset is ten pixels if the command key is pressed, one pixel if it isn’t.
Note. Translating with arrow keys is implemented only in mode kCADModeTranslate and in mode kCADModeReshape (if this mode can translate). In other situations a kCADEventIDKeyDown or kCADEventIDAutoKeyDown event is generated.
(286) Scaling linewidths in block inserts is now on by default. CADGetXPrefs and CADSetXPrefs have been removed (cf. note 266).
(287) The starting point of objects to create can no more be outside CAD drawing bounds. Trying to do so initiates no event and no new object. The same is true for to-be-inserted string objects. The special click mode however does generate an event for clicks outside drawing bounds.
Note. An event parameter now indicates whether the special click is inside or outside drawing bounds.
(288) String objects are now shown upto a font size of 1 point.
(289) The zoom state of the printing-preview is saved and restored separately.
(290) The state of theBackToFrontFlag of a string object is now independent of theJustification parameter. Flipping a string object swaps the Justification as well as theBackToFrontFlag (cf. CADGetStringXY , CADSetStringAlign, CADObjString ).
(291) CADGetMatSpecs has been replaced by CADGetMatrixPlane .
(292) Subtle changes to the CAD color palette (to make it 24-bit unique).
(293) The orientation of linetypes of rotated circles was wrong. This has been fixed.
(294) CADAddArray , CADSetArray , CADRemoveArray and CADCopyArrays can now be called with the Clipboard area as the target area.
(295) Moved the origin of blocks imported with CADImportDXF (if out of logical bounds).
(296) Solved known issues of CADCancelDXF
- Imported linetypes were not removed
- Imported sublayers were not removed.
Solved known issue of CADAcceptDXF
- The CADtoDXFUnitFactor was ignored.
(297) Solved known issues of continous zooming.
(298) Solved known painting problem of thick circle-arcs and thick ellipse-arcs (cf. note 27).
(299) Translate mode and rotate mode have been removed from the command palette.
- Mode constants have changed !
- Translate mode is available with CADSetMode and custom palettes.
- Rotate mode is unimplemented.
(300) Inserts of empty blocks can now be selected (by intersection, by enclosure and by line).
(301) Selecting ellipse objects with radiusx = 0.0 or radiusy = 0.0 was incorrect. This has been fixed.
(302) CADSetDrawSize now rounds (insets) the drawing bounds to the largest possible pixel size (which is the pixel size of the smallest possible zoom out). This guarantees that pixel-to-coordinate transformations round to whole pixels.
(303) Automatic resize of the drawing bounds no longer scrolls to arbitrary positions.
(304) Clicking on the zoominfo box resets an error message displayed in it.
(305) CADFindByLock is new. Source and target scope can be the same.
(306) CADGetArrayIDs is new.
