This task shows you how to select multiple surfaces and perform
modification. This task deals with:
|
 |
Open the
MultiSelection.CATPart
document. |
 |
-
Click Modification
in the Modification toolbar.
-
Select Subdivision Surface.1.
-
Click Multi-Selection
.
 |
You can also access this command by pressing
CTRL+SPACE. |
-
Press Crtl
key and select Subdivision Surface.3.
-
Click Multi Selection
and
you are back to Modification
command.
|
 |
- In case
of multiple selection of subdivision surfaces, each subdivision mesh
is displayed in a different color for easier
identification.
- To display the meshes in same default color, clear the
check box Automatic colored in Multi-Selection Mode in
Tools > Options > Shape > Imagine & Shape > Display tab.
The default color is as specified in
Tools > Options > General > Display > Visualization
tab, Color area.
- There is no set rule for the order of colors to be displayed. If
you deselect or reselect a subdivision, its color may change.
- Selected elements are displayed in red color and the
pre-selected elements in orange as the previous behavior and these colors are kept for
the elements in all the meshes.

Modification of Multiple Surfaces
|
|
-
Select the faces on these two subdivision surfaces. You can use the
Ctrl
key to multi-select the faces. You can add, remove and change the
selected faces.
The All Elements Selection
will select all the faces of the two subdivision surface.
-
Click Translation
.
-
Move the mouse cursor to highlight the desired axis or
plane.
-
Hold down the left-mouse button and drag to translate the
surfaces.
-
Release the left-mouse button when you are satisfied with
the new position of the surfaces.
|
|
Use One Subdivision Surface to Modify Another
|
|
-
Click Compass Definition
to define the compass' position on Subdivision Surface.3.
-
Click Compass Definition
again.
-
Click Alignment
.
-
Select the multiple edges or vertices on Subdivision Surface.1
to align them on Subdivision Surface.3. You can use the Ctrl
key to multi-select the vertices. You can add, remove and change the
selected vertices.
-
Click the manipulator to project the edges.
You can see that the edges are projected.
 |
The result is: |
 |
|
 |
- All modification commands can be applied to multiple surfaces.
- When you work with more than a one subdivision surface, if
the working zone option is activated (or deactivated); it will
be activated (or deactivated) for the entire selected subdivision
surfaces. For more information on working zone, refer to
Defining The Working Zone.
- If you have selected the faces or edges or
vertices of a subdivision, and further deselected the subdivision,
then reselecting this subdivision will highlight all previously
selected elements.

Smart Selection of Multiple Surfaces
|
 |
Open the
SmartSelection.CATPart
document. |
 |
In case a feature has more than one parent, it is possible to select
and modify the required subdivision surfaces using the Crtl
key.
Using the Parents/Children... contextual menu command, you
can see that the edge fillet (EdgeFillet.1) feature has three
subdivision surfaces as parent. |
 |
-
Select
EdgeFillet.1 and click Modification
to modify it.
You can see that all the parent subdivision surfaces are highlighted in
the specification tree. The Tools Palette
also appears.
-
Press
Ctrl
key and select the parent subdivision surfaces you want to modify.
In
this case select two subdivision surfaces.
-
Click
End Selection
in the Tools Palette
to validate the selection.
You can see that the selected subdivision surfaces can now be modified.
|
 |
If Ctrl key is not pressed and you select a surface in
geometry, then the modification of the selected surface starts
immediately without any validation. Multiple surfaces cannot be selected
in geometry. |
