Displaying and Editing Graphic Properties

This task shows you how to display and edit the graphic properties of a selected object using the Properties dialog box.

Before you start, note the following general information:

Inheritance for Assembly objects

The following properties can be inherited: color, transparency, line type and line weight. This inheritance can be deactivated by doing one of the actions below depending on the property you do want to inherit:

Select No Color in the Color list
Select No Linetype in the Linetype list
Select No Width in the Thickness list
Clear the option next to the Transparency slider.

For detailed information on graphic properties applied to products, refer to "Managing Graphic Properties in Products" in the Version 5 - Product Structure User's Guide.

Inheritance for Mechanical Modeler objects

When a mechanical object (a pad, for instance) has been assigned a color, this color is used to display the object. Otherwise, the object is displayed using the color of its father element (i.e. the part body).
To reset the inheritance from the father to the children, select Reset properties from the Edit menu or from the pad's contextual menu. Bear in mind that this command cancels any local modification applied to the graphic properties of the pad (including color and transparency)
The following properties are set at the part body level and cannot be inherited: point symbol, line thickness and line type.

For detailed information on graphic properties applied to products, refer to "Displaying and Editing Bodies Properties" in the Version 5 - Part Design User's Guide.

Materials

When a material has been applied onto a part with Material selected in View > Render Style > Customize View (or with Shading with Material selected in the View toolbar), the graphic properties defined in the Properties dialog box have no impact on the part display anymore.
As a consequence, if you need to modify the transparency, for instance, this must be done in the material properties. For detailed information on modifying material properties and on materials in general, refer to the Version 5 - Real Time Rendering User's Guide.

Select the object whose graphic properties you want to display.

The object to be selected when using the Part Design application is the part body item in the specification tree.

Select Edit > Properties command (or press ALT+Enter) or right-click then select Properties.

A Properties dialog box similar to the one below is displayed (note that the tabs might be displayed in a different order depending on the object you select):

Click the Graphic tab to display the graphic properties of the current object:


In the above dialog box, the graphic properties available for editing are: `Color` (colors the current object) and `Transparency` for the fill `Color`, `Linetype` and `Thickness` for edges `Line`, `Linetype` and `Thickness` for lines and curves `Color` and `Symbol` for points `Show` and `Pickable` attributes `Low Intensity` `Layers` `Rendering Style`.
Note that when displaying the graphic properties of an Assembly object, the dialog box looks like this:

	If you select an Assembly object and another object type (point, line, etc.) simulatenously, only one `Properties` dialog box is displayed. For instance, here the object is an Assembly object, so the dialog box dedicated to Assembly objects opens but in that case, you will only be able to modify the graphic properties of the Assembly object. Other object types will not be impacted by your changes.
For detailed information on graphic properties applied to products, refer to "Managing Graphic Properties in Products" in the Version 5 - Product Structure User's Guide.

To set object colors, use the Color list.

A list appears containing: A blank color box (No Name) A list of sixteen default colors from the color palette, ready for use `More Colors...` `No Color` (for Assembly objects only).

	`No Color` lets you deactivate the color inheritance for Assembly objects. You can then apply a color onto a face without having to modify the product color. To do so: Select the product. Access the `Properties` dialog box. Choose `No Color` in the `Color` list. Select the face onto which you want to apply the color. Access the face's graphic properties. Select the desired color from the `Color` list.

Select the desired color.

The selected color is now displayed in the field. Pointing the cursor over the list displays the name of the selected color.

Color on Mechanical Modeler objects

In a CATPart context, it is not possible to apply a color to the part itself but only to the part body and its sub-elements. If you access the part properties, the Graphic tab is grayed out.
For more information, refer to the Version 5 Part Design User's Guide - Displaying and Editing Bodies Properties.

Color on Assembly objects

When applying a color onto an Assembly object, any other element located at a lower level in the specification tree inherits this color and the list displays the color of the Assembly object. However, the color modification impacts only the display at rendering level and not the graphic properties. This can be useful, for instance, to highlight an object among others without altering its graphic properties.
To deactivate the inheritance mechanism, click the Color list: all the elements located at a lower level have their own color back and No Color is displayed in the list.

When working with Edges and points and Shading selected, the color applied to the product is also applied to the mesh but not to lineic elements (edges, sketches, etc.) which turn black. In this case, it not possible to modify the color of these lineic elements.
However, when working with the Edges and points check box selected, the color applied to the product is also applied to lineic elements.

Color on surfaces

You can apply a color on surfaces' sub-elements. Let's suppose the following model:

If you select the the sub-element "EdgeFillet.1" then access its graphic properties, you see that the fillColor list is available:

You can then select the desired color from the combo box and click Apply or OK to confirm.
The color is applied to the selected face only:

Note:

If you modify the geometry, the sub-element keeps its color when the geometry is updated.
If you create a new feature using the sub-element's surface, the color of the sub-element is not propagated to the new feature.

To access more colors, or to create your own colors, click More Colors... at the bottom of the list to access the Color palette:

In the Basic Colors area, among the 48 colors provided, 16 are the same as those in the previous list. The remaining are extra colors.

The Custom Colors area contains sixteen free boxes in which you can place your custom colors.

Click Define Custom Colors >> to display the full color palette and color customization tools:


	The colored area with the cross represents a color spectrum. Drag the cross inside the spectrum to instantaneously change the color in the small box below the spectrum. The HSL (Hue, Saturation and Luminance) and RGB (Red, Green and Blue) values vary according to where the cross is located. You can also enter HSL and RGB values in the fields provided to suit your exact color specifications. HSL is an alternate model to RGB model for color specification and is illustrated by the scheme below:

Move the arrow up or down to vary the brightness of the custom color:

Once you are happy with the color, click one of the free boxes in the Custom Colors area, then Click Add to Custom Colors to add the customized color.
Click on the custom color, then OK.

The color is now displayed in the Color fill box of the Graphic Properties tab.
Click Apply in the Properties dialog box.

The color of the selected object is changed.

To make the part more or less transparent, drag the Transparency slider to set the appropriate value (between 0 and 255).

Two transparency modes are available via the Performance tab in Tools > Options:

Screen Door
Alpha Blending.

For more information, refer to Customizing Performance Settings.

Note that:

Regarding .asm documents, you can select or clear the Transparency check box to apply or not a transparency inheritance independently from the color of the selected object.
If you apply transparency on a solid (or on one or more of its faces) on which you perform a section cut using any Version 5 sectioning commands, the interior of this solid then is not materialized.

To set color edges on parts, use the Color list for edges and proceed the same way.
To set edge line type and thickness, use the appropriate lists.
If you have selected a line or a curve, you can set the line and curve color, the linetype and thickness the same way as for parts.
If you have selected a point, you can set the point color in the same way as for parts. To select the symbol used to represent the point, select the symbol from the Symbol list.
In the Global Properties area, the Shown check box indicates if the object is always visible (i.e. in Show mode) or always hidden (i.e. in No Show mode). This check box is displayed for information only and cannot be modified.

For more information about the show and no show modes, refer to Hiding and Showing Objects.
Still in the Global Properties area, select the Pickable check box if you want the object to always be selectable.

The Layer list indicates the number of layers the selected objects are assigned to. Otherwise (when nothing is selected) it indicates the current layer.

When pointing to the Layer list, a tootip indicates whether the layer definition location is stored in the document or in the user settings (i.e. the CATSettings directory).
However, bear in mind that this tooltip is displayed for information only, you cannot modify the storage location which has been set as explained below:

For .CATProduct documents, the definition is stored in the user settings.
For .CATPart documents, the definition (if there is one) is stored in the document. If no definition is stored in the document, the .CATPart documents use the definition stored in the user settings.
For .CATDrawing documents, the definition is stored in the document.

Use the list to choose among the list of named layers and assign the chosen layer to the selected objects: None, 0 General, 1-999 (according to the number of layers in the Layer list). For more information, refer to Assigning Objects to Layers.

The Layer box also contains the Other Layers... command which lets you create your own named layers. Refer to Creating New Layers for more details.

Select the Low Intensity check box to apply the low-intensity color to the selected element. This property enables you to filter the visualization of any geometry by applying a specific color.

By default, the color to be applied to low-intensity elements is "dark green" but you can modify it in Tools > Options > General > Display > Visualization.

Elements can be put in low-intensity state by:

Selecting the Low Intensity check box in the Graphic tab of the Properties dialog box.
Right-clicking any view from the geometry area or the specification tree then selecting Background > Low-intensified when working with the 2D Layout for 3D Design product. Refer to the dedicated documentation for more information.
Clicking Low intensity background in the 2D Visualization toolbar of the Sketcher product or in the Tools toolbar of the Generative Shape Design or Wireframe and Surface product, for instance. Refer to the dedicated documentation for more information.
However, note that representations on a green background (such as measures) are not clearly displayed when set to Low intensity background or Unpickable low intensity background because of the superimposition of the low intensity mode's dark green color:


`Low intensity background` or `Unpickable low intensity background` is deactivated	`Low intensity background` or `Unpickable low intensity background` is activated

It is possible to keep the low-intensity state for 2D or 3D objects displayed in Shading with Material rendering style. This means that when you apply the low-intensity state to objects onto which materials have been applied, the low-intensity state is kept even though elements are visualized in Shading with Material.

This is illustrated by the examples below showing two parts onto which materials have been applied:


`Low Intensity` check box is cleared The materials applied onto the two parts are displayed	`Low Intensity` check box is selected The materials are not displayed anymore ; they are overriden by the low-intensity color
As soon as you clear the `Low Intensity` option, the materials are displayed.

The Rendering Style list lets you select the rendering style you want to apply to the selected element, provided that this element supports rendering styles.
This rendering style will then be used to visualize the object independently from the rendering style applied to the 3D window when using the Enable object view mode visualization mode.

Note that this option is identical to the one provided in the Graphic Properties toolbar.

Rendering styles can be applied only on .CATPart documents or on .CATPart documents embedded in .CATProduct documents:

Part Body
You can apply a rendering style to each body composing the part body and this, even if a body is embedded into another one.
All the elements gathered in the part body or in the body inherit the rendering style of their parent. As a consequence, you cannot apply a rendering style to the child solid features (such as a pad or a fillet).
Geometrical Set
You can apply a rendering style to the Geometrical Set as a whole and to each child feature in the graph ; each feature may be applied a different rendering style. If no rendering style has been applied to a feature, this feature will be displayed with the rendering style applied to the father element or, if no father exists, with the rendering style of the viewer used to display the feature.

Shape Body
The behavior is identical to the one of the Geometrical Set except that different child features may share the same visual representation and therefore, the same rendering style.

By default, no rendering style is applied but you can choose among the following styles:
