|
|
|
\n This geometrical operation allows to perform a symmetrical copy of
|
|
your mesh or some of its elements.
|
|
|
|
<em>To create a symmetrical copy:</em>
|
|
|
|
<ol>
|
|
<li>From the \b Modification menu choose \b Transformation -> \b Symmetry item or click
|
|
<em>"Symmetry"</em> button in the toolbar.
|
|
|
|

|
|
|
|
One of the following dialogs will appear:
|
|
|
|
It is possible to mirror a mesh or some of its elements through:
|
|
\image html symmetry1.png "a point" <br>
|
|
\image html symmetry2.png "an axis" <br>
|
|
\image html symmetry3.png "a plane (defined by a point and a normal to the plane)"
|
|
|
|
</li>
|
|
|
|
<li>In the dialog:
|
|
<ul>
|
|
<li>specify the elements for the symmetry operation:
|
|
|
|
<ul>
|
|
<li><b>Select the whole mesh, submesh or group</b> activating this
|
|
checkbox; or</li>
|
|
<li>choose mesh elements with the mouse in the 3D Viewer. It is
|
|
possible to select a whole area with a mouse frame; or</li>
|
|
<li>input the element IDs directly in <b>ID Elements</b> field. The
|
|
selected elements will be highlighted in the viewer; or</li>
|
|
<li>apply Filters. <b>Set Filter</b> button allows to apply a
|
|
\ref filtering_elements "filter" to the selection of elements.</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>depending on the nature of the mirror object:
|
|
<ul>
|
|
<li>if the mesh is mirrored through a point, specify the coordinates
|
|
of the point, either directly or by picking a mesh node;</li>
|
|
<li>if the mesh is mirrored through an axis:
|
|
<ul>
|
|
<li>specify the coordinates of the start \b Point of the axis, either
|
|
directly or by picking a mesh node;</li>
|
|
<li>specify the components of axis \b Vector, either directly or by
|
|
picking a mesh node, in which case \b Vector is defined as a shift
|
|
between the \b Point and the node;</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>if the mesh is mirrored through a plane:
|
|
<ul>
|
|
<li>specify the cooordinates of the \b Point lying on the plane,
|
|
either directly or by picking a mesh node;</li>
|
|
<li>specify the components of plane \b Normal, either directly or by
|
|
picking a mesh node, in which case \b Normal is defined as a shift
|
|
between the \b Point and the node.</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>specify the conditions of symmetry operation:
|
|
<ul>
|
|
<li>activate <b>Move elements</b> radio button to change location of
|
|
the selected elements within the current mesh;</li>
|
|
<li>activate <b>Copy elements</b> radio button to duplicate the
|
|
selected elements at the new location within the current mesh;</li>
|
|
<li>activate <b>Create as new mesh</b> radio button to create new
|
|
element in a new mesh; the new mesh appears in the Object Browser
|
|
with the default name MeshName_mirrored (it is possible to change
|
|
this name in the adjacent box);</li>
|
|
<li>activate <b> Copy groups </b> checkbox to put new mesh enities
|
|
into new groups if source entities belongs to some groups. New
|
|
groups are named by pattern "<old group name>_mirrored".</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
<li>activate <b>Preview</b> checkbox to show the result of
|
|
transformation in the viewer;</li>
|
|
<li>click \b Apply or <b> Apply and Close</b> button to confirm the
|
|
operation.</li>
|
|
</ul>
|
|
|
|
</ol>
