<title>Doing Measurements</title>
|
|
<keyword name="Rulers"/>
|
|
|
|
<p>
|
|
A measurement can be performed by clicking on the ruler icon in the
|
|
toolbar and selecting "Ruler" from the drop-down options.
|
|
Left-click on a point in the layout and then left-click again to
|
|
specify the second point. A ruler will be shown that indicates
|
|
the distance measured.
|
|
</p>
|
|
|
|
<p>
|
|
A more convenient way is provided with the single-click measurement
|
|
ruler. Select "Measure" from the drop-down options of the ruler symbol.
|
|
In this mode, a single click will set a ruler to the specified
|
|
position. This feature will look for edges in the vicinity of the
|
|
ruler and set the ruler to connect the neighboring edges. The ruler
|
|
is attached perpendicular to the edge next to the initial point.
|
|
</p>
|
|
|
|
<p>
|
|
Rulers can be configured in manifold ways. Use "Rulers And Annotations Setup"
|
|
in the "Edit" menu to open the ruler configuration dialog.
|
|
A ruler can be
|
|
made to snap to edges of objects by selecting "Snap to edge/vertex".
|
|
Ruler orientations can be constrained by using the "Angle Constraint"
|
|
options. The number of rulers can be limited using the "Limit
|
|
number of annotations" setting.
|
|
</p>
|
|
|
|
<p>
|
|
While drawing or moving one point of a ruler, the direction constraint
|
|
can be overridden with the Shift and Ctrl keys: pressing Shift while moving the
|
|
mouse will enforce orthogonal constraint, Ctrl will enforce diagonal constraint
|
|
while pressing both will release any direction constraint.
|
|
</p>
|
|
|
|
<p>
|
|
All rulers can be cleared using the "Clear all rulers" function from the
|
|
"Edit" menu.
|
|
</p>
|
|
|
|
<p>
|
|
Ruler dragging can be canceled with the "Esc" key or using the "Cancel"
|
|
function from the "Edit" menu.
|
|
</p>
|
|
|
|
<p>
|
|
Rulers can be moved by selecting "Move" mode with the speedbar buttons
|
|
in the toolbar or "Move" from the "Mode" submenu in the "Edit" menu. Then
|
|
left-click and drag the ruler or the ruler end point that should be changed.
|
|
</p>
|
|
|
|
<p>
|
|
Rulers can be deleted selectively by selecting a ruler in "Select" mode and
|
|
pressing "Delete".
|
|
</p>
|
|
|
|
<p>
|
|
Rulers can be modified in a variety of ways. For example, rulers can be shown
|
|
as arrows. To edit the properties of a ruler, double-click the ruler or
|
|
select it and use "Properties" from the "Edit" menu.
|
|
See <link href="/manual/ruler_properties.xml"/> for a description of the
|
|
properties.
|
|
</p>
|
|
|
|
<p>
|
|
Multiple templates can be configured to be available for rulers. Each template defined
|
|
will be shown in the "Ruler" mode toolbar button's drop-down menu.
|
|
If a template is selected, new rulers produced from this template will inherit
|
|
the template's properties. Templates are managed in the
|
|
ruler setup page ("Setup" from the "File" menu) or "Ruler And Annotation Setup" from the "Edit" menu.
