|
\n This geometrical operation allows to scale in space your mesh
|
|
or some of its elements.
|
|
|
|
<em>To scale a mesh:</em>
|
|
|
|
<ol>
|
|
<li>From the \b Modification menu choose \b Transformation -> \b Scale
|
|
\b Transform item.
|
|
|
|
One of the following dialogs will appear:
|
|
|
|
With one scale factor:
|
|
\image html scale01.png
|
|
|
|
Or with different scale factors for axes:
|
|
\image html scale02.png
|
|
|
|
</li>
|
|
|
|
<li>
|
|
In the dialog:
|
|
<ul>
|
|
<li>specify the IDs of the translated elements:
|
|
|
|
<ul>
|
|
<li><b>Select the whole mesh, submesh or group</b> activating this
|
|
checkbox; or</li>
|
|
<li>choose mesh elements with the mouse in the 3D Viewer. It is
|
|
possible to select a whole area with a mouse frame; or</li>
|
|
<li>input the element IDs directly in <b>ID Elements</b> field. The selected elements will be highlighted in the
|
|
viewer; or</li>
|
|
<li>apply Filters. <b>Set filter</b> button allows to apply a filter to the selection of elements. See more
|
|
about filters in the \ref selection_filter_library_page "Selection filter library" page.</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>specify the base point for scale</li>
|
|
|
|
<li>specify the scale factor</li>
|
|
|
|
<li>specify the conditions of scale:
|
|
<ul>
|
|
<li>activate <b>Move elements</b> radio button to create the source
|
|
mesh (or elements) at the new location and erase it from the previous location;</li>
|
|
<li>activate <b>Copy elements</b> radio button to create the source
|
|
mesh (or elements) at the new location, but leave it at the previous
|
|
location, the source mesh will be considered one and single mesh with
|
|
the result of the scale operation;</li>
|
|
<li>activate <b>Create as new mesh</b> radio button to leave the
|
|
source mesh (or elements) at its previous location and create a new
|
|
mesh at the new location, 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);</li>
|
|
<li>activate <b> Copy groups </b> checkbox to copy the groups of elements of the source mesh to the newly created mesh.</li>
|
|
</ul>
|
|
</li>
|
|
|
|
</li>
|
|
|
|
<li>activate <b>Preview</b> checkbox to show the result of transformation in the viewer </li>
|
|
<li>click \b Apply or <b> Apply and Close</b> button to confirm the operation.</li>
|
|
</ul>
|
|
</ol>
|
|
|
|
|
|
|
|
<b>Example of using:</b>
|
|
|
|
1. Create quandrangle mesh 3x3 on a simple planar face (200x200)
|
|
|
|
\image html scaleinit01.png
|
|
|
|
and union 3 faces (along axis Z) to group "gr_faces"
|
|
|
|
\image html scaleinit02.png
|
|
|
|
|
|
|
|
2. Perform scale operation for the whole mesh and create a new mesh:
|
|
|
|
\image html scale03.png
|
|
|
|
result after operation:
|
|
|
|
\image html scaleres03.png
|
|
|
|
|
|
|
|
3. Perform scale operation for the whole mesh and copy elements:
|
|
|
|
\image html scale04.png
|
|
|
|
result after operation:
|
|
|
|
\image html scaleres04.png
|
|
|
|
|
|
|
|
4. Perform scale operation for a group of faces and copy elements:
|
|
|
|
\image html scale06.png
|
|
|
|
result after operation:
|
|
|
|
\image html scaleres06.png
|
|
|
|
|
|
|
|
5. Perform scale operation for two edges and move elements:
|
|
|
|
\image html scale07.png
|
|
|
|
result after operation:
|
|
|
|
\image html scaleres07.png
|
|
|
|
|
|
|
|
6. Perform scale operation for one face and move elements:
|
|
|
|
\image html scale09.png
|
|
|
|
result after operation:
|
|
|
|
\image html scaleres09.png
|
