Drawing Basic Shapes
The two ends of the segment will be made up of a square at one end and an
arrow at the other.
The segments drawn will have an angle that is a multiple of 45° to the
horizontal axis. You can get the same effect by pressing the Ctrl key when you
draw your line.
This button lets you display the dimensions of the object being drawn. A
dimension object includes a double-headed arrow, two segments that indicate
the extremities of the measured zone, and a measure in the current unit of
measure.
If a dimensioned object is resized, the corresponding change in size is
recalculated automatically and displayed. If you group an object with
dimensions, any change in the size of the object will be reflected in the sizes
reported in the dimensions. In such a case, we call them associated dimensions.
The dimensions can be configured using a dialog box that is available from the
local dimensions menu.
The dimensions are shown as default in the unit of measurement corresponding
to that of the sheet. You can change the units using the menu Format >
Dimensions.
The Dimensioning options dialog lets you set up the positions of the elements
that make up the dimension. You can enter line thicknesses, distance and
overhang to the guide marks, text position and also change the unit of
measurement displayed (or even not to display the unit of measurement).
You can also set the line type and text attributes using the classical available
functions already discussed.
With this tool; you can draw a segment bearing arrows at each end.
Connectors
Connectors are a particular type of curve, the ends of which are attached to gluepoints on
other objects, and which stick to these gluepoints when the associated object is moved. They
are particularly useful for making organizational charts. You can reorganize the blocks of
your chart while keeping the links between them.
OpenOffice.org Draw has a whole panoply of functions that are really quite remarkable as far
as connectors are concerned. Finding the various functions is not at first sight very easy, but
we shall look at the ways of making them visible.
Connector drawing basics
The principle behind drawing a connector is as follows: all objects have gluepoints associated
with them. The gluepoints are invisible by default. The connectors you can draw position
themselves automatically onto the gluepoints of the object. Draw sets the default number of
gluepoints for an object to 4. We will see later how you can change the position of the
gluepoints and add new ones.
