7 This geometrical operation allows to scale in space your mesh or some of its elements.
11 #. From the **Modification** menu choose **Transformation** -> **Scale Transform** item.
12 One of the following dialogs will appear:
14 With one scale factor:
16 .. image:: ../images/scale01.png
19 Or with different scale factors for axes:
21 .. image:: ../images/scale02.png
25 * specify the IDs of the translated elements:
26 * **Select the whole mesh, submesh or group** activating this checkbox; or
27 * choose mesh elements with the mouse in the 3D Viewer. It is possible to select a whole area with a mouse frame; or
28 * input the element IDs directly in **ID Elements** field. The selected elements will be highlighted in the viewer; or
29 * apply Filters. **Set filter** button allows to apply a filter to the selection of elements. See more about filters in the :ref:`selection_filter_library_page` page.
31 * specify the base point for scale
33 * specify the scale factor
35 * specify the conditions of scale:
37 * activate **Move elements** radio button to scale the selected mesh (or elements) without creating a copy;
38 * activate **Copy elements** radio button to duplicate the selected mesh (or elements) and to apply scaling to the copy within the same mesh;
39 * activate **Create as new mesh** radio button to leave the selected mesh (or elements) at its previous location and create a new mesh of the scaled copy of the selected elements; the new mesh appears in the Object Browser with the default name MeshName_scaled (it is possible to change this name in the adjacent box);
40 * activate **Copy groups** checkbox to copy the groups of elements existing in the source mesh to the newly created mesh.
42 * activate **Preview** checkbox to show the result of transformation in the viewer
43 * click **Apply** or **Apply and Close** button to confirm the operation.
48 #. Create quandrangle mesh 3x3 on a simple planar face (200x200)
50 .. image:: ../images/scaleinit01.png
53 and union 3 faces (along axis Z) to group "gr_faces"
55 .. image:: ../images/scaleinit02.png
60 #. Perform scale operation for the whole mesh and create a new mesh:
62 .. image:: ../images/scale03.png
65 result after operation:
67 .. image:: ../images/scaleres03.png
70 #. Perform scale operation for the whole mesh and copy elements:
72 .. image:: ../images/scale04.png
75 result after operation:
77 .. image:: ../images/scaleres04.png
80 #. Perform scale operation for a group of faces and copy elements:
82 .. image:: ../images/scale06.png
85 result after operation:
87 .. image:: ../images/scaleres06.png
92 #. Perform scale operation for two edges and move elements:
94 .. image:: ../images/scale07.png
97 result after operation:
99 .. image:: ../images/scaleres07.png
104 #. Perform scale operation for one face and move elements:
106 .. image:: ../images/scale09.png
109 result after operation:
111 .. image:: ../images/scaleres09.png
