These options define different modes of creating drawing views.
These command operation modes can be also specified in the properties window
(parameter “Type” in the group “Basic parameters”). The command's properties
window and the auto menu work synchronously.
Working with Draggers of Drawing View
For defining location, rotation angle and dimensions of the drawing view, a special type of the cursor in the
form of the dynamically movable rectangle with markers is used. Markers can be used for modifying
location, rotation angle, the scale and the size of the view, location of the fixing vector or fixing point.
The markers are used as follows: a marker is activated simply by pointing the cursor and clicking . Then
the marker can be moved to the desired position. The second click fixes the new position of the view.
Alternatively, the marker can be “dragged” by moving the cursor with the mouse button held down. In
this latter case, the placement of the view in the new position occurs on releasing the mouse button.
As the placement or parameters of the view are modified, the original state stays in display.
To change the view box size, the square-shape markers are used, located in the corners and at side midpoints
of the view box. When pointed at by the cursor, the latter changes to a two-headed arrow .
The marker provides for modifying the view scale, that is the scale factor of the page display in the view
box. The exact value of the scale can be entered in the view parameters dialog box.
The marker allows changing the view rotation angle about the fixing point. (In the case the view was
based on an existing page and a fixing vector, this will be the rotation angle of the fixing vector.) The exact
value of the rotation angle can be entered in the view parameters dialog box.
For moving the view image relative to the page, on which it is located, the marker or the marker of the
fixing point of the view (in the form of the filled square) can be used.
Location of the fixing point of the view is shown with the marker in the form of the unfilled square. When
creating the drawing view on the basis of the existing page with the help of the fixing vector, the location of
the given marker coincides with the origin of the fixing vector.
For modifying the fixing point of the view, point at the marker for fixing the view while holding the button
. After that, to select the fixing point, you can pick (by pressing ) one of the characteristic
points of the view box (corners of the view box and the midpoints of its sides). You can also specify the
fixing point of the view arbitrarily by using + .
It is also possible to change the location of the fixing point of the view with the help of the option
of the auto menu for the command of creating/editing the drawing view.
