This task shows how to manage
and customize the sub-geometry selection in order to avoid any ambiguity. |
|
This toolbar is available in any workbench
dealing with .CATPart and .CATProduct documents. Note that this scenario
takes the Generative Shape Design workbench as an example but
the look and number of icons available in the User Selection Filter
toolbar varies according to the workbench in which you are working.
For detailed information on icons dedicated to a specific workbench, refer to the documentation of
interest.
|
|
- A Version 5 - P2 Generative Shape Design configuration is required to
follow this scenario.
- A .CATProduct containing a .CATPart must be open and one or more
features created.
You can also open the
SelectionFilter.CATProduct document
-
Activate the User Selection Filter toolbar by
selecting View > Toolbars > User Selection Filter.
|
|
|
|
The toolbar is divided into
several
sections:
Filter type
-
Point Filter
to filter points
-
Curve Filter
to filter curves
-
Surface Filter
to filter surfaces
-
Volume Filter
to filter volumes.
|
|
Filter mode
-
Feature Element Filter
selects the whole feature whether it is a sketch, product, pad, join,
etc.
-
Geometrical Element Filter
enables to sub-elements of a feature such as faces, edges or vertices.
|
|
Work on Support selection state
This command
is used in conjunction with the Work on Support command and
lets you select sub-elements from the grid. Refer to "Working with
a 3D Support" in the Version 5 - Generative Shape Design
User's Guide for detailed information. This command
is only available with the Automotive Body in White Templates product. |
|
Quick Select
This command
lets you perform a quick selection of geometry. Refer to "Quick
Selection of Geometry" in the Version 5 - Generative Shape
Design User's Guide for detailed information. This
command is only available with the Generative Shape Design 2 product. |
|
Intersection edges activation
This command
enables to create an intersection edge: the selection of the edge is
propagated to the whole intersection. It ensures a better stability as
the intersection edge is automatically recomputed when the shape of the
feature on which it lies is modified. The intersection edge can only be applied on a modification feature.
Refer to "Creating Edge Fillets" in the Version 5 -
Generative Shape Design User's Guide for detailed information.
This command is only available with the Generative Shape Design 2 or Part
Design products. |

Tangent Intersection Edges activation

Reset Selection Filters
Lets you deactivate the filter icons that
have been previously activated in the User Selection Filter
toolbar (i.e. icons listed in the Filter type
section detailed above, other icons are not impacted). To use this command, you can choose between the following three
methods:
- type
c:Reset Selection Filters in the power input
field: all the icons are deactivated
- select View > Commands List then select Reset
Selection Filters from the list before clicking OK to
validate: this deactivates all the icons in the toolbar
- select Tools > Customize, access the Commands
tab, select All Commands in the Categories list
then drag and drop the Reset Selection Filters command onto
the User Selection Filter toolbar (or any other toolbar):
You can then check Reset Selection Filters when needed to
deactivate the toolbar icons.
|
|
-
Click Feature Element Filter
as shown:
|
By default, all the icons are
deactivated which means that no filter is applied but you can restrict the
selection to specific element types by clicking the corresponding icons.
For instance, if you want to select only points and surfaces, you need to
activate the Point Filter and Surface Filter icons as
shown below: |
|
|
- If you deselect a type, it cannot be selected in the geometry anymore
unless all other types are deselected
- If you deselect a mode, it cannot be selected anymore for each active
type unless other modes are deselected
- It is not possible to
activate both filter modes simultaneously (it does not make sense
anyway). Only two states are available: either Feature Element
Filter or Geometrical Element Filter is activated or
both modes are deactivated.
|
|
Depending on the filter you select, the following
cursors are used:
- When the selection is forbidden, the shape
is used and this,
whatever the filter you select
- When a filter other than Geometrical Element Filter
(e.g. Feature Element Filter, Point Filter,
etc.) is activated , the cursor shape is
when pointing at an
element and the hourglass is displayed after selecting the
element
- When Geometrical Element Filter is activated, the
cursor shape is when
pointing at an element and the hourglass is also displayed after
selecting the element.
