<h2>4.3 Moving and scaling objects</h2>
<p>
There are three modes for transforming objects: <em>move</em>
(translate), <em>stretch</em>, and <em>rotate</em>. If you hold the shift
key while pressing the left mouse button, the stretch function keeps
the aspect ratio of the objects (an operation we call <em>scaling</em>),
and the move function is restricted to horizontal and vertical
translations.
<p>Normally, the transformation functions work on the current selection.
However, to make it more convenient to move around many different
objects, there is an exception: When the mouse button is pressed while
the cursor is not near the current selection, but there <em>is</em> some
other object close to the cursor, <em>that</em> object is moved,
rotated, or scaled instead.
<p>By default, the <em>rotate</em> function rotates around the center of
the bounding box for the selected objects. This behavior can be
overridden by specifying an
<a href="manual_25.html">axis system</a>. If an axis system is
set, then the origin is used as the center.
<p>The <em>scale</em> and <em>stretch</em> functions use a corner of the
bounding box for the selected objects as the fix-point of the
transformation. Again, if an axis system is set, the origin of the
system is used instead.
<p>It is often convenient to rotate or scale around a vertex of an
object. This is easy to achieve by setting the origin of the
axis system to that vertex, using the <em>Snap to vertex</em>
function for setting the <a href="manual_24.html">axis
system</a>.
