Micro-PWC CONFIGURATION GUIDE
106 Grafx Editor
When scaled equally, objects are increased or decreased in height or width by the same proportion. To
scale an object equally in both the X and Y dimensions, press and hold the
S HIFT key prior to selecting a
handle.
To scale an object relative to its center, press and hold the
C TRL key prior to selecting the resize handle. To
scale an object equally around its center, press and hold both the
S HIFT and
C TRL keys while dragging one of
the object's resize handles.
4.2.6.8.1 Changing an Object's Reference Point
Each object has one reference point. By default, the reference point of an object is defined as the center of
the object's extent. The Rotate option (described in the following sub-section) makes use of an object's ref-
erence point.
To change the reference point of a selected object, position the pointer on the object and click the right
mouse button. From the resulting pop-up menus, select the sequence Points > Change Ref then click on a
point other than the center of the object. If a single object is on the Select List when the Change Ref func-
tion is invoked, this change in reference point remains in effect permanently for the instance of that sub-
model in the graphic. If more than one object has been selected, however, the change in reference point is
in effect only while the objects are selected.
Use the Reset Ref option on the Points pop-up menu to set the reference point of each object on the
Select List back to its default, the center of the object's extent.
The reference point can be used in conjunction with Point Snap mode to aid in the placement and intercon-
nection of objects and submodels on a graphic. See
Section 4.2.8, Object Placement Example .
4.2.6.9 Rotating an Object
The Rotate feature rotates selected objects. An object rotates around its reference point, which by default
is the center of the object's extent. Position the pointer on the object to be rotated, then click the right
mouse button. Choose Rotate from the resulting pop-up menu.
A dashed reference line appears, with the left end of this line at the object's reference point. The reference
line is an aid for choosing the angle of rotation. The angle to rotate the selected object(s) is chosen by
clicking a point relative to the reference point and reference line. The number of degrees between the ref-
erence line and the selected point, calculated counterclockwise, determines the angle of rotation.
4.2.6.10 Changing the Drawing Order of Objects
The Raise button on the VIEW toolbar is used to modify the order in which objects are drawn on the
screen. Objects are normally drawn in the order in which the user created them. If two objects overlap, the
object which was created more recently is drawn later, and therefore appears on top of (and obscuring) the
older object.
✎ Note The Rotate feature can also be accessed using the Grafx menus by
selecting the menu sequence Edit > Object > Rotate.
