\n This geometrical operation allows to perform a symmetrical copy of
|
|
your mesh or some of its elements.
|
|
|
|
<em>To create a symmtrical copy of the mesh:</em>
|
|
|
|
<ol>
|
|
<li>From the \b Modification menu choose \b Transformation -> \b Symmetry item or click
|
|
<em>"Symmetry"</em> button in the toolbar.
|
|
|
|
\image html symmetry.png "Symmetry button"
|
|
|
|
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 (defined by a point and a vector)"
|
|
\image html symmetry2.png "an axis"
|
|
\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 IDs of 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 filter to the selection of elements. See more
|
|
about filters in the \ref selection_filter_library_page "Selection filter library" page.</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</li>
|
|
<li>if the mesh is mirrored through an axis:
|
|
<ul>
|
|
<li>specify the cooordinates of the start \b Point of the axis vector;</li>
|
|
<li>specify the axis \b Vector through the coordinates of its
|
|
end point with respect to the coordinates of the start point;</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;</li>
|
|
<li>specify the axis \b Vector through the coordinates of its
|
|
end point with respect to the coordinates of the start point.</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>specify the conditions of symmetry operation:
|
|
<ul>
|
|
<li>activate <b>Move elements</b> radio button to create the source
|
|
mesh (or elements) at the new location and erase it from the previous location;</li>
|
|
<li>activate <b>Copy elements</b> radio button to create the source
|
|
mesh (or elements) at the new location, but leave it at the previous
|
|
location, the source mesh will be considered one and single mesh with the result of the rotation;</li>
|
|
<li>activate <b>Create as new mesh</b> radio button to leave the
|
|
source mesh (or elements) at its previous location and create a new
|
|
mesh at the new location, the new mesh appears in the Object Browser
|
|
with the default name MeshName_rotated (it is possible to change this
|
|
name in the adjacent box);</li>
|
|
<li>activate <b> Copy groups </b> checkbox to copy the groups of elements of the source mesh to the newly created mesh.</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
<li>Click \b Apply or <b> Apply and Close</b> button to confirm the
|
|
operation.</li>
|
|
|
|
</ol>
