Scale¶
This geometrical operation allows to scale in space your mesh or some of its elements.
To scale a mesh:
From the Modification menu choose Transformation -> Scale Transform item.
The following dialogs will appear, where you can select how to scale:
with one scale factor:
or with different scale factors for axes:
- In the dialog:
- specify the IDs of the translated elements:
Select the whole mesh, submesh or group activating this checkbox; or
choose mesh elements with the mouse in the 3D Viewer. It is possible to select a whole area with a mouse frame; or
input the element IDs directly in ID Elements field. The selected elements will be highlighted in the viewer; or
apply Filters. Set filter button allows to apply a filter to the selection of elements. See more about filters in the Selection filter library page.
specify the base point for scale
specify the scale factor
specify the conditions of scale:
activate Move elements radio button to scale the selected mesh (or elements) without creating a copy;
activate Copy elements radio button to duplicate the selected mesh (or elements) and to apply scaling to the copy within the same mesh;
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);
activate Copy groups checkbox to copy the groups of elements existing in the source mesh to the newly created mesh.
activate Preview checkbox to show the result of transformation in the viewer
click Apply or Apply and Close button to confirm the operation.
Example of using:
Create quandrangle mesh 3x3 on a simple planar face (200x200)
and union 3 faces (along axis Z) to group “gr_faces”
Perform scale operation for the whole mesh and create a new mesh:
