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 axes:
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 scale the selected
48 mesh (or elements) without creating a copy;</li>
49 <li>activate <b>Copy elements</b> radio button to duplicate the selected
50 mesh (or elements) and to apply scaling to the copy within the same mesh;</li>
51 <li>activate <b>Create as new mesh</b> radio button to leave the
52 selected mesh (or elements) at its previous location and create a new
53 mesh of the scaled copy of the selected elements; the new mesh appears in the Object Browser
54 with the default name MeshName_scaled (it is possible to change this
55 name in the adjacent box);</li>
56 <li>activate <b> Copy groups </b> checkbox to copy the groups of
57 elements existing in the source mesh to the newly created mesh.</li>
63 <li>activate <b>Preview</b> checkbox to show the result of transformation in the viewer </li>
64 <li>click \b Apply or <b> Apply and Close</b> button to confirm the operation.</li>
70 <b>Example of using:</b>
72 1. Create quandrangle mesh 3x3 on a simple planar face (200x200)
74 \image html scaleinit01.png
76 and union 3 faces (along axis Z) to group "gr_faces"
78 \image html scaleinit02.png
82 2. Perform scale operation for the whole mesh and create a new mesh:
84 \image html scale03.png
86 result after operation:

92 3. Perform scale operation for the whole mesh and copy elements:
94 \image html scale04.png
96 result after operation:

102 4. Perform scale operation for a group of faces and copy elements:

112 5. Perform scale operation for two edges and move elements:
114 \image html scale07.png
116 result after operation:
