About Generating Hatched Areas from 3D Specifications

Hatched areas in generative views are used to define or highlight some specific 3D areas to represent some type of technological information such as painting, chemical treatment, thermal treatment, etc. You can generate associative 2D hatched areas in generative views from a dedicated 3D specification.

However, before you begin generating hatched area, you need to understand the concepts that are described in this topic.

This page discusses:

To create associative 2D hatched areas:

  • You need to specify the 3D areas in the work area through the Note Object Attribute (NOA) defined in the 3D Tolerancing & Annotation app.
  • You also need to specify the same NOA in the associated generative view style which is used to generate 2D views. For more information, see Generating Hatched Areas from 3D Specifications.

Extraction of 3D Area

You can extract the dedicated NOA type specification in 2D generative views as generated shapes.

Note: Dimensions and annotations created on these generated shapes are not associative with 3D.

Standard Generative Views

  • You can generate 2D hatched areas in all the standard generative views by defining the dedicated type NOA specifications to be extracted as a hatched area in the generative view style.
  • You can also generate hatched areas in section, detail, clipping, broken, breakout and 3D clipping views.

View From 3D

You can generate 2D hatched areas in views generated from 3D, that is from 2D Layout for 3D Design by defining the NOA specifications dedicated to be extracted as a hatched area in the generative view style.

Views from 3D Tolerancing & Annotation: In this case, all the Note Object Attributes are extracted as annotations. No hatched areas are generated.

Note: Only the annotations belonging to the current active view are considered.

Important: If the NOA specifications to be extracted are overlapping with each other (that is, several NOA are associated to the same face, whether they are created in the same product or not), extracted hatched areas may overlap in the resulting view.

View Update

When modifications are applied to the used NOA specifications, the drawing representation requires an update and the Update icon is activated.

Supported View Projection Modes

During the view update process, modifications done in the dedicated NOA specifications are extracted only in the views generated in the exact projection mode.

Pattern Associated to the Projected Area

The default pattern used for hatched areas is the pattern defined in the dedicated generative view style file. The specified pattern name has to be defined in the standard associated to the drawing. For more information about defining pattern parameters, see 3D Tolerancing & Annotation Parameters.

Note: If you define a pattern name, which does not belong to standard, then a default hatching pattern is used.

All the patterns associated to a given extracted 3D typed NOA specifications are associative even if:

  • Hatched areas are belonging to different generative views.
  • Pattern is manually modified.

    Modification is propagated to all areas linked to the same extracted 3D typed NOA specifications.

Notes:
  • You can independently modify the pattern properties associated to different extracted 3D typed NOA specifications using the context menu command Properties.
  • After you modify the pattern graphical properties, they are kept during next view updates. That is, the subsequent views will be generated using this modified pattern.

Overloading Properties

The added overload properties attributes are relative to the selected 3D instance.

For more information about overloading properties, see Overloading Element Properties.

Consider the following points when overloading properties of generated shapes:

  • Use when projecting: If this check box is cleared, then the 3D typed NOA belonging to the unused instance will not be created.
  • Shown: If this check box is cleared, then the 3D typed NOA belonging to the not-shown instance will not be created.

Annotation Set Hide/Show Behavior

The generation of resulting 2D hatched area in standard generative views is independent of the hide/show status of the dedicated type NOA specification.

Note that this NOA specification is considered as a technological specification and not as a 3D geometry.
