5 \n In MESH you can add to your mesh different elements such as:
8 <li>\ref adding_nodes_anchor "Nodes"</li>
9 <li>\ref adding_0delems_anchor "0D Elements"</li>
10 <li>\ref adding_edges_anchor "Edges"</li>
11 <li>\ref adding_triangles_anchor "Triangles"</li>
12 <li>\ref adding_quadrangles_anchor "Quadrangles"</li>
13 <li>\ref adding_polygons_anchor "Polygons"</li>
14 <li>\ref adding_tetrahedrons_anchor "Tetrahedrons"</li>
15 <li>\ref adding_hexahedrons_anchor "Hexahedrons"</li>
16 <li>\ref adding_octahedrons_anchor "Hexagonal prism"</li>
17 <li>\ref adding_polyhedrons_anchor "Polyhedrons"</li>
20 <em>To add a node or an element to your mesh:</em>
22 <li>Select your mesh in the Object Browser or in the 3D viewer.</li>
24 <li>From the \b Modification menu choose the \b Add item, the
25 following associated submenu will appear:</li>
27 \image html image146.png
29 From this submenu select the type of element which you would like to add to your mesh.
31 \note All dialogs for new node or element adding to the mesh (except for
32 the dialog for 0D elements) provide the possibility to automatically add
33 a node or element to the specified group or to create the anew using
34 <b>Add to group</b> box, that allows choosing an existing group for
35 the created node or element or giving the name to a new group. By
36 default, the <b>Add to group</b> check box is switched off. If the user
37 swiches this check box on, the combo box listing all currently
38 existing groups of the corresponding type becomes available. By
39 default, no group is selected. In this case, when the user presses
40 <b>Apply</b> or <b>Apply & Close</b> button, the warning message box
41 informs the user about the necessity to input new group name. The
42 combo box lists both \ref standalone_group "standalone groups"
43 and \ref group_on_geom "groups on geometry". If the user chooses a
44 group on geometry, he is warned and proposed to
45 \ref convert_to_standalone "convert this group to standalone".
46 If the user rejects conversion operation, it is cancelled and
47 a new node/element is not created!

80 \anchor adding_edges_anchor
83 \image html addedge.png
85 In this dialog box specify the nodes which will form your edge by
86 selecting them in the 3D viewer with pressed Shift button and click
87 the \b Apply or <b>Apply and Close</b> button. Your edge will be created:

97 In this dialog box specify the nodes which will form your triangle by
98 selecting them in the 3D viewer with pressed Shift button and click
99 the \b Apply or <b>Apply and Close</b> button. Your triangle will be created:

104 \anchor adding_quadrangles_anchor
105 <h2>Adding quadrangles</h2>
107 \image html addquadrangle.png
109 In this dialog box specify the nodes which will form your quadrangle
110 by selecting them in the 3D viewer with pressed Shift button and click
111 the \b Apply or <b>Apply and Close</b> button. Your quadrangle will be created:
113 \image html add_quadrangle.png
116 \anchor adding_polygons_anchor
117 <h2>Adding polygons</h2>
119 \image html addpolygon.png
121 In this dialog box specify the nodes which will form your polygon by
122 selecting them in the 3D viewer with pressed Shift button and click
123 the \b Apply or <b>Apply and Close</b> button.

133 In this dialog box specify the nodes which will form your tetrahedron
134 by selecting them in the 3D viewer with pressed Shift button and click
135 the \b Apply or <b>Apply and Close</b> button. Your tetrahedron will be created:

145 In this dialog box specify the nodes which will form your hexahedron
146 by selecting them in the 3D viewer with pressed Shift button and click
147 the \b Apply or <b>Apply and Close</b> button. Your hexahedron will be created:

155 In the Add Hexagonal Prism dialog box specify the nodes which will
156 form your hexagonal prism by selecting them in the 3D viewer with pressed Shift button and click
157 the \b Apply or <b>Apply and Close</b> button. Your hexagonal prism will be created:

165 \image html a-createpolyhedralvolume.png
167 There are two different ways to add polyhedral volumes.
168 \n If you select \b Node as <b>Elements Type</b> you will specify the
169 nodes which will form the faces of your polyhedron by selecting the
170 nodes in the 3D viewer with pressed Shift button and clicking the \b
171 Add button to add the face in the list of Faces by Nodes, which will
172 form your polyhedron. Note, that it could be very useful to toggle
173 Polyhedron Preview checkbox to see the results of your selection.
174 \n The second way is somewhat simpler, however, there are cases when
175 it does not provide you with the necessary level of precision. If you
176 select \b Face as <b>Elements Type</b>, you will be able to select the faces
177 which will form your polyhedron in the 3D viewer with pressed Shift
178 button. If you've managed to obtain the necessary result, click the
179 \b Apply or <b>Apply and Close</b> button. Your polyhedron will be created:
