This task shows you how to display and modify
the dress-up options for curve, surface and face. |
|
Open the
FreeStyle_Part_50.CATPart document. |
|
-
Click Dress-Up
in the Generic Tools
toolbar.
The Curves and surfaces dress-up dialog box is displayed.
|
-
Select the elements you want to dress in the
Objects box.
In the Objects box, selected elements can be of
two types:
- Individual elements, for instance: curve,
surface, or face.
- Set of elements, for instance: Geometrical Set,
Ordered Geometrical Set, or PartBody.
|
You can select one or several elements by doing one of the
following:
- To select a single element, click the element in
either the work area or the tree.
- To select multiple elements:
- Click
next to
the Objects box to display the
Objects list dialog box.
- Select the required object.
- If necessary, remove or replace objects in the
Objects list dialog box.
- Click Close.
OR
- Hold down Ctrl and select the
required elements.
- Press F8.
Dress-Up applied to sets of elements (or to
individual elements, respectively) enables to associate
a Dress-Up's representation for each element of the sets
(respectively for each individual element).
Once applied to sets of elements (or to individual
elements, respectively), Dress-Up's representations are
automatically updated according to the changes (shape
modification, moving, deletion or addition of elements)
occurring within the sets (or onto the individual
elements, respectively). The element name or the number
of selected elements is displayed in the Objects box.
|
|
|
|
You can select the Geometric Set or valid elements (surfaces
and curves) under it as input elements. Press Ctrl key for multiple selection of
geometric sets.The
icon
lets you edit the list of surfaces selected for analysis. Click the icon
to display the Objects List dialog box that allows you to
remove or replace the selected elements.

The dialog box has three areas: Curves, Surfaces and
Faces. |
|
Curves: This area has following options, |
|
- Control Points: Select this
check box to display the control points on
the selected curves with the settings as
defined in the dialog box. By default this
option is deactivated.
- You can define the color of the
control points mesh.
- You can define the line type of
the control points.
- You can define the control point
style.
- Segmentation: Select this
check box to display the segmentation on the
selected curves with the settings as defined
in the dialog box. By default this option is
deactivated.
- You can define the color of the
segmentation points.
- You can define the segmentation
point style.
|
|
Surfaces: This area has following options, |
|
- Control Points: Select this check box
to display the control points on the
selected surfaces with the settings as
defined in the dialog box. By default this
option is deactivated.
This option functions exactly identical to
the
Control Points option in the
Curve
area.
- Display control points on edges:
Select this check box to display the control
points only on the edges of the selected
surfaces. By default this option is
deactivated.
|
When control points on the surface are not
displayed, this option allows you to display the control
points on the limit edges of the surface
only. |
- Segmentation: Select this check
box to display the segmentation on the
selected surfaces with the settings as
defined in the dialog box. By default this
option is deactivated.
This option functions exactly identical to
the
Segmentation option in the
Curve
area.
- You can define the line type of
the segmentation.
- Iso-curves: Select this check box
to display the number of U and V
isoparametric curves on the selected
surfaces with the settings as defined in the
dialog box. By default this option is
deactivated.
- You can define the color of the
isoparametric curves.
- You can define the isoparametric
curve style.
- You can define the number of U
and V isoparametric curves from the
NbU and NbV
drop-down lists. The number can be
any number from the list or Order.
Order displays the isoparametric
curves in U and V corresponding to the
internal mathematical order of the
surface.
For example, if the order of the surface is 5
in U and 3 in V,
you can see that 5 iso-curves in U
direction and 3 in V direction are
displayed.
|
Faces: This area has following options, |
- Control Points: Select this
check box to display the control points on
the selected faces with the settings as
defined in the dialog box. By default this
option is deactivated.
This option functions exactly identical to
the
Control Points option in the
Surface area.
- Segmentation: Select this
check box to display the segmentation on the
selected surfaces with the settings as
defined in the dialog box. By default this
option is deactivated.
This option functions exactly identical to
the
Segmentation option in the
Surface
area.
- Iso-curves: Select this check
box to display the number of U and V
isoparametric curves on the selected
surfaces with the settings as defined in the
dialog box. By default this option is
deactivated.
This option functions exactly identical to
the
Iso-curves option in the
Surface
area.

There are three states of the options
available in the Curves and surfaces dress-up dialog box:
- Not selected: When the selected elements
do not have any dress-up feature defined,
the options in the Curves and surfaces dress-up
dialog box are not selected.
- Selected: When the selected elements
have the same parameters (color, linetype,
symbol and selection of the option) for the
defined dress-up feature, such options are
selected in the Curves and surfaces dress-up
dialog box.
- Undefined: When the selected elements
have the different parameters (color,
linetype, symbol and selection of the
option) for the defined dress-up feature,
such options are in undefined state in the Curves and surfaces dress-up
dialog box.
|
-
The option will remain in undefined state
till you change it.
