View

You can customize view options for Drafting using this section.

You can customize the geometry generation and dress-up options while generating views. You can also specify the type of view generation mode, display of dimensions in the clipping view, 2D geometry generation while creating a view from 3D and so on.

This page discusses:

Geometry Generation / Dress-Up

This category of options lets you specify what kind of geometry and dress-up elements you want to generate when generating views.

Generate axis

Select this check box to generate axis lines.

Important: The view plane must be parallel to the rotation face axis. Rotation faces made out of fillets are not taken into account when generating axis lines.



By default, this check box is cleared.

Generate threads

Select this check box to generate threads.

Threads can be represented in two different ways:

  • From the front and rear (whether or not the hole is threaded along its whole depth).
    Important: In this case, the view plane must be perpendicular to the rotation face axis. The face must be a threaded hole or a thread. The representation of the rotation face in the view must exceed 180 degrees.


  • From the side.
    Important: In this case, the view plane must be parallel to the rotation face axis. The face must be a threaded hole or a thread.




By default, this check box is cleared.

Generate centerlines

Select this check box to generate centerlines.

Important: The view plane must be perpendicular to the rotation face axis. The representation of the rotation face in the view must exceed 180 degrees.



By default, this check box is cleared.

Generate hidden lines

Select this check box to generate hidden lines. Selecting this check box enables the Auto-hide check box.

By default, this check box is cleared.

Auto-hide
Select this check box to simplify the representation of hidden lines in the view.

By default, this check box is cleared.

Generate Smooth Edges
Select this check box to generate smooth edges.

By default, this check box is cleared.

Generate patterns

Select this check box to generate patterns.

By default, this check box is selected.

Generate fillet

Select this check box to generate fillets.

Click Configure to configure fillet generation. For more information, see Fillet Generation.

By default, this check box is selected.

Inherit 3D colors

Select this check box if you want the colors of a 3D shape to be automatically generated onto the views.

Important: Whenever the projected geometry color is the same as the sheet background color, the geometry color is changed to a more visible one, even if this option is selected. Thus, in the event the sheet and projected geometry are the same color, the inherited color may not be applied.

By default, this check box is cleared.

Project 3D wireframe

Select this check box to visualize both the wireframe and the geometry on generated views.

Click Configure to configure 3D wireframe projection. For more information, see 3D Wireframe Projection.

By default, this check box is cleared.

Project 3D points

Select this check box to project points from 3D (no construction element).

Click Configure to configure 3D point projection. For more information, see 3D Point Projection.

By default, this check box is cleared.

View Linetype

Click Configure to configure linetypes and thicknesses for specific types of views: section view, detail view, broken view, breakout view, skin section view (in the case of wireframes and surfaces). For more information, see Linetype and Thickness.

View Generation

Shaded Background Mode

Select this check box to create exact views with shaded background. This check box is available for selection only when the View generation mode is Exact view.

When you select this check box, you can click Configure. In the Shaded Background Mode Options dialog box that appears, you can customize the preferences.

Under Shaded Background Mode Options, you can customize the following preferences:

  • Mode: You can create views with Shading or with Shading, no light source. There can be a minor difference in the shading of the view because of the light source. You can select the With texture check box to represent the texture of the part in the view.
  • Level of detail: You can select the level of detail for the visualization mode and for the print mode. There are four levels of detail for each mode:
    Level of detail Default value for visualization Default value for visualization print Editable values? (Yes or No)
    Low quality 36 36 No
    Normal quality 145 145 No
    High quality 580 580 No
    Customize 91 300 Yes

In the Hatching/Dotting Pattern Background for Operators area, you can customize the hatching or dotting pattern for background operators such as section views or cuts, callouts, details, and breakout operators.

  • Select Color from 3D to inherit the hatching or dotting pattern as defined on the 3D part. By default, this is selected.
  • Select Color from Palette to select the required color from the palette.
You can select the color for the hatching and dotting patterns. For fill color and image pattern, the selected color has no effect.

View generation mode

Select how you want to generate views. The options in the View generation mode field are as follows:

  • Exact view: Select this option to generate exact views from the Design mode, that is, views for which the geometry is available. The exact generation mode is the best option in most cases.

    If you select the Exact view mode, you can click Configure to customize the preference for the integration of 3D polyhedral data.

  • CGR : Select this option to generate views using the CGR format (CATIA Graphical Representation). CGR corresponds to a data format containing a graphical representation of the geometry only, which is available with the Visualization mode (as opposed to the exact geometry, which is available with the Design mode). With CGR, only the external appearance of the component is used and displayed; the geometry is not available.
  • Approximate: Select this option to generate views in Approximate mode. Although Approximate views are not as high in precision and quality as exact views, this generation mode dramatically reduces memory consumption. Performance may also be improved, depending on how you fine-tune the precision. Therefore, the Approximate mode is particularly well adapted to sophisticated products or assemblies involving large amounts of data.

    If you select Approximate mode, click Configure to fine-tune the generation options according to your needs. For more information, see Approximate Mode.

  • Raster: Select this option to generate views as images. This enables you to quickly generate overall views for large products or assemblies, regardless of drawing quality. Such views are associative to the 3D geometry and can be updated when the 3D shape or product changes.

    If you select Raster mode, click Configure to fine-tune the generation options according to your needs. For more information, see Raster Mode Options.

    Recommendation: To optimize disk space and memory consumption, do not select the Inherit 3D colors option when generating raster views.

By default, By default, Exact view mode is selected.

For a detailed description (including the advantages and restrictions pertaining to each view generation mode), see 3D Modeling Apps : Mechanical Systems: Drafting User's Guide: Creating Views: View Creation Concepts: About the View Generation Mode.

3D extracted representations

Select the type of 3D representation that you want to project in the view. The options in the 3D extracted representations list are as follows:

  • All design representations: Select this option to create a view from all design representations.
  • First design representations: Select this option to create a view from only the first level of design representations. In the example below, the first design representations are surrounded in blue.

    Notes:
    • The above options only consider representations having the V_nature attribute as Definition.
    • If the first-level representation has the V_nature attribute as Specification, the second level is considered as the first-level representation.
  • As session: Select this option to create a view from all 3D representations in session.
  • All representations: Select this option to create a view from all representations.
  • First representations: Select this option to create a view from only the first-level representations.

By default, All design representations is selected.

Only generate 3D shapes larger than

Select this check box to specify that you only want to generate 3D shapes, which are larger than a certain size, and indicate the appropriate size by providing a value in millimeters in the appropriate field.

By default, this check box is cleared.

Enable occlusion culling

Select this check box if you want to save memory when generating exact views from an assembly, which is loaded in Visualization mode (that is, when the Work with the cache system option is active). This loads only the 3D shapes that are seen in the resulting view (instead of loading all of them, which is the case by default), which optimizes memory consumption and CPU usage.

To ensure the efficiency of this option, make sure that the Exact preview for view generation option is not selected.

In the case of an assembly, which is loaded in Design mode, or in the case of a 3D shape, the Enable occlusion culling option helps to increase performance by reducing CPU usage.

Note: Keep the following restrictions in mind when selecting the Enable occlusion culling option:
  • The Project 3D points option is disabled.
  • The only option available for Project 3D wireframe is Can be hidden.

By default, this check box is cleared.

Clash detection
Select this check box to identify the clash and project the clashing bodies in the Exact view generation mode.

Clipping View

Put in no show dimension on non-visible geometry

Select this check box if you want the dimensions to put automatically in no show mode, which are attached to geometry that is not visible in clipping views.

Note: This option is applicable only to Exact views.

If you do not select this check box, dimensions are displayed in clipping views using the colors defined in the Element AnalysisElements Analysis, accessible through Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > Drafting > Display tab, under Element Analysis, select the Activate Elements' analysis check box.

The color used depends on whether the dimension is interactive (that is, created manually) or generated automatically:

  • Interactive dimensions are displayed using the color defined for dimensions on nonvisible geometry (light blue by default).
  • Generated dimensions are displayed using the color defined for dimensions generated from 3D constraints (light green by default).
Important: Dimensions are put in no show mode only if none of the geometric elements to which the dimension is attached are visible. If an element is visible while the other is not, the dimension is displayed using the color defined by the analysis display mode as specified above.

By default, this check box is selected.

View from 3D

Generate 2D geometry

Select this check box if you want to generate 2D geometry (that is, wireframe and 2D points) when generating a view from 3D from a layout view (2D Layout for 3D Design app).

By default, this check box is selected.

Copy view with link synchronization

Synchronize Copy View With Link objects during update
Select this check box to synchronize the CopyViewWithLink object along with the target view update.

By default, this check box is cleared.

Broken view

Default Break Lines Gap
Providing a value in millimeters in the appropriate field for the break lines gap.

By default, the value is 5mm.
