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.
13 The following dialogs will appear, where you can select how to scale:
15 * with one scale factor:
17 .. image:: ../images/scale01.png
20 * or with different scale factors for axes:
22 .. image:: ../images/scale02.png
26 * specify the IDs of the translated elements:
27 * **Select the whole mesh, submesh or group** activating this checkbox; or
28 * choose mesh elements with the mouse in the 3D Viewer. It is possible to select a whole area with a mouse frame; or
29 * input the element IDs directly in **ID Elements** field. The selected elements will be highlighted in the viewer; or
30 * 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.
32 * specify the base point for scale
34 * specify the scale factor
36 * specify the conditions of scale:
38 * activate **Move elements** radio button to scale the selected mesh (or elements) without creating a copy;
39 * activate **Copy elements** radio button to duplicate the selected mesh (or elements) and to apply scaling to the copy within the same mesh;
40 * 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);
41 * activate **Copy groups** checkbox to copy the groups of elements existing in the source mesh to the newly created mesh.
43 * activate **Preview** checkbox to show the result of transformation in the viewer
44 * click **Apply** or **Apply and Close** button to confirm the operation.
49 #. Create quandrangle mesh 3x3 on a simple planar face (200x200)
51 .. image:: ../images/scaleinit01.png
54 and union 3 faces (along axis Z) to group "gr_faces"
56 .. image:: ../images/scaleinit02.png
61 #. Perform scale operation for the whole mesh and create a new mesh:
63 .. image:: ../images/scale03.png
66 result after operation:
68 .. image:: ../images/scaleres03.png
71 #. Perform scale operation for the whole mesh and copy elements:
73 .. image:: ../images/scale04.png
76 result after operation:
78 .. image:: ../images/scaleres04.png
81 #. Perform scale operation for a group of faces and copy elements:
83 .. image:: ../images/scale06.png
86 result after operation:
88 .. image:: ../images/scaleres06.png
93 #. Perform scale operation for two edges and move elements:
95 .. image:: ../images/scale07.png
98 result after operation:
100 .. image:: ../images/scaleres07.png
105 #. Perform scale operation for one face and move elements:
107 .. image:: ../images/scale09.png
110 result after operation:
112 .. image:: ../images/scaleres09.png
