5 \n This geometrical operation allows to scale in space your mesh
6 or some of its elements.
8 <em>To scale a mesh:</em>
11 <li>From the \b Modification menu choose \b Transformation -> \b Scale
14 One of the following dialogs will appear:
16 With one scale factor:
17 \image html scale01.png
19 Or with different scale factors for axises:
20 \image html scale02.png
27 <li>specify the IDs of the translated elements:
30 <li><b>Select the whole mesh, submesh or group</b> activating this
32 <li>choose mesh elements with the mouse in the 3D Viewer. It is
33 possible to select a whole area with a mouse frame; or</li>
34 <li>input the element IDs directly in <b>ID Elements</b> field. The selected elements will be highlighted in the
36 <li>apply Filters. <b>Set filter</b> button allows to apply a filter to the selection of elements. See more
37 about filters in the \ref selection_filter_library_page "Selection filter library" page.</li>
41 <li>specify the base point for scale</li>
43 <li>specify the scale factor</li>
45 <li>specify the conditions of scale:
47 <li>activate <b>Move elements</b> radio button to create the source
48 mesh (or elements) at the new location and erase it from the previous location;</li>
49 <li>activate <b>Copy elements</b> radio button to create the source
50 mesh (or elements) at the new location, but leave it at the previous
51 location, the source mesh will be considered one and single mesh with
52 the result of the scale operation;</li>
53 <li>activate <b>Create as new mesh</b> radio button to leave the
54 source mesh (or elements) at its previous location and create a new
55 mesh at the new location, the new mesh appears in the Object Browser
56 with the default name MeshName_scaled (it is possible to change this
57 name in the adjacent box);</li>
58 <li>activate <b> Copy groups </b> checkbox to copy the groups of elements of the source mesh to the newly created mesh.</li>
64 <li>Click \b Apply or <b> Apply and Close</b> button to confirm the operation.</li>
69 <b>Examle of using:</b>
71 1. Create quandrangle mesh 3x3 on simple planar face (200x200)
73 \image html scaleinit01.png
75 and union 3 face (along axis Z) to group "gr_faces"

81 2. Perform scale opration for whole mesh with creation of new mesh:
