Displaying and Modifying Dress-Up Features  

Open the FreeStyle_Part_50.CATPart document.

1. Click Dress-Up in the Generic Tools toolbar.
   The Curves and surfaces dress-up dialog box is displayed.

2. 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.

• 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.

• 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.

  • 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.

• 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.

•  Visibility modes for the points, wires, and axes –

  By default, the Default Points Visibility Mode , Default Wires Visibility Mode , and Default Axes or Planes Visibility Mode are selected. The visibility options for the points, wires, and axes are set as per the settings of the No points, No wires, and No axes check boxes in the View Mode Customization dialog box, respectively. For more information, see the CATIA Infrastructure: Customizing the View Mode. Notes:  Click Hide Points , Hide Wires , and Hide Axes or Planes to hide the point, wire, and axis entities, respectively. Click Show Points , Show Wires , and Show Axes or Planes to show the point, wire, and axis entities, respectively.  If you first define or modify the visibility options for points, wires, and axes in the View mode Customization dialog box and then create a variant, the visibility options will be in the default mode in the Curves and surfaces dress-up dialog box. Click Hide Points , Hide Wires , and Hide Axes or Planes to hide the point, wire, and axis entities, respectively.

3. Select the curve.

4. In the Curve area, select the Control Points and Segmentation options. You can change the color, linetype and style also.

5. Click Apply.

6. Select the Apply immediately check box.

• 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.

• You can press F8 key to change the selection state. After selecting elements, press F8 and modify the parameters you want to. In this state your existing selection will not be deselected even if you click anywhere in the 3D area. Press F8 again to go back to the selection state.
