About Views from 3D

View from 3D

You can generate the following types of view from 3D:

• Projection views, section views, section cuts,
• Aligned section views, aligned section cuts, offset section views, offset section cuts.

For more information about a view from 3D, see View.

2D Components

The Note Object Attribute (NOA) from a 2D component is extracted in views from 3D. However, some restrictions apply:

• Information regarding the documents used to create the ditto (drawing, parts, catalogs) are lost.
• Hidden texts and URLs on flag notes and Note Object Attributes are lost during extraction.

Annotations

• You can move or modify annotations in views from 3D. However, if the part is modified and you then update the view, any modification applied to the annotations in the drawing is lost. Thus, perform the modifications directly on the 3D part.
• 2D annotations can be added to views from 3D.
• Changing the color of 3D annotations to white will not impact the color of annotations in the drawing: they are automatically displayed using the black color (instead of white) so that they can be readable against a white background.

Associativity

• Views from 3D are not associative to the geometry of the 3D view. If you modify the geometry of a 3D view, the definition of the corresponding 2D view is not modified at the next update, even if the 3D view is associative to the geometry.
• Extracted annotations are not associative to the geometry.

• As the extracted annotations & dimensions are a non-associative copy of the 3D annotation and dimension, they do not consider any modification of the view from 3D definition, such as adding clipping or break operators, but are consistent with the 3D annotation and dimension.

  Only associative annotations and dimensions, added directly in the view from 3D, take these modifications into account as they do in other types of views.

Dimensions

Curvilinear dimensions and chamfer dimensions generated with a view from 3D cannot be manipulated and are seen as not up to date (using the color defined for Dimensions for which last update failed in the Elements' Analysis dialog box available through Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > Drafting > Display section, under Elements Analysis, selecting the Activate element's analysis check box, and by clicking Configure...).

3D Tolerancing & Annotation Display Ratio

In 3D Tolerancing & Annotation, you can define a ratio to reduce or emphasize the display of an annotation. When generated,

• For front views, section views and section cuts, the ratio of the 3D annotation view is reversed and applied to the view geometry in the generated 2D drafting view.
• For aligned section views/section cuts and offset section views/section cuts, the ratio of the first 3D annotation view is reversed and applied to all the generated 2D drafting views.

Hidden 3D Geometry

Only the elements visualized in 3D (that is, in Show mode) at the time of extraction are extracted in the view from 3D. In other words, any element hidden in 3D does not appear in the view. So if you show this element in the 3D part, then update the view from 3D, this element is displayed.

Standard

The parent standard used in the drawing representation and in the 3D Part (annotations) must be the same. Otherwise, both the view and the annotations may not be generated.

View from 3D Axis and Section Cut Callout

In a view from 3D, the H and V axis of the view must correspond to X and Y axis of the sheet. Therefore, the choice of the view in which to add a section cut callout is limited. In particular, the profile of the section cut must be horizontal on the chosen view. In the case of extraction views, the first line of the profile (that is, corresponding to the first compounding view) must be horizontal.

Generation of Drawings or Views from 3D Using Generative View Styles

You can generate a drawing view from a 2D Layout for 3D Design view, which uses a generative view style. In this case, the generative view style is entirely managed in the 2D Layout for 3D Design view and layout.

• If the 2D Layout for 3D Design view is associated with the generative view style, then the generated view also has the same generative view style. However, you cannot modify or delete the associated generative view style.
• Views extracted from a layout with embedded generative view styles turn to not-up-to-date in the following cases:
  • When an embedded generative view style is synchronized with its corresponding XML file, it is added to the layout or removed from the layout.
  • When a generative view style is applied to, or removed from, any view in the layout.
• To use the generative view style:
  • Clear the Disable generative view style usage check box in Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > 2D Layout for 3D Design > Administration section, under Generative view style.
  • Clear the Disable generative view style usage check box in Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > Drafting > Administration section, under Generative view style.

Generation of View Background Geometry and Annotations

You can generate a drawing view displays the 2D layout elements (that is, geometry and annotations) seen in the background of a 2D Layout for 3D Design view that.

The following 2D elements seen in the background of a 2D layout view are generated, independently without specifying any option and even if placed behind another 3D object:

• Geometry of other 2D layout views.
• Annotations of other 2D layout views as well as annotations of 3D Tolerancing & Annotation views.
• Dressup.

These elements are generated with the following restrictions:

• The element has to belong to the layout assembly.
• In case of an annotation or geometry, its support plane has to be parallel to the 2D layout view plane, and the annotation or geometry should be readable (that is, not seen from behind.)

Impact of Clipping Frame

The clipping frame specified on a 2D Layout for 3D Design view is a visualization operator that clips the elements displayed in the background of the 2D Layout for 3D Design view.

It means that the view background geometry is cut if it crosses the clipping area. As a consequence, the resultant drawing is generated with generative items trimmed on the clipping outlines.

However, the annotations and dressup elements are not trimmed on the clipping outlines. They are generated if at least one representative point is present inside the clipping area. Else, they are not generated in the view background.

The following table provides the information of the representative points of all possible annotations and dressup objects:

Type	Objects	Representative Point
Annotations	Balloon Datum feature Datum target Dimension Geometrical tolerance Roughness symbol Table Text with leader View text Welding symbol	Text box corners
Dressup	Center line Axis line Thread Arrow Area fill	Origin Extremities Origin Extremities Contour extremities
Other	2D component instance	Origin

Generation of 3D Tags

You can generate 3D tags in a drafting view from a 2D layout view.

In the Standard Definition dialog box, select the Common3DModeling node. From the Extraction list, select Yes (available through Me > Preferences > Standards > generativeparameters category).

When 3D tags are created on a part body, they can be generated while creating views in drafting. For more information about creating 3D tags, see Generative Shape Design User's Guide: Creating 3D Tags.
