AlignShellElementNormalBuilder Class — NXOpen Python API Reference 12.0.0 documentation

# AlignShellElementNormalBuilder Class

class `NXOpen.CAE.ModelCheck.``AlignShellElementNormalBuilder`

  Bases: `NXOpen.Builder`

  Represents a `NXOpen.CAE.ModelCheck.AlignShellElementNormalBuilder` builder used to align the normals of connected shell elements with a seed shell element.

  You can align the normals by executing either `Builder.Commit()` or `NXOpen.CAE.ModelCheck.AlignShellElementNormalBuilder.AlignNormals()`. The difference between these two methods is `Builder.Commit()` aligns the normals and updates normal display, but it does not return the elements that have changed normals. `NXOpen.CAE.ModelCheck.AlignShellElementNormalBuilder.AlignNormals()` aligns the normals and returns the elements that have changed normals. Both of the methods are only available in fem context.

  To create a new instance of this class, use `NXOpen.CAE.ModelCheckManager.CreateAlignShellElementNormalBuilder()`

  New in version NX8.5.0.

# Properties

Property | Description
--- | ---
ElementConnectScope | Returns or sets the option to indicate how to define connected elements for checking
ReverseSeedNormal | Returns or sets the option indicating whether to reverse element normals so that they are aligned with the seed element
SeedElement | Returns or sets the seed element
Tag | Returns the Tag for this object.
UserSpecifiedConnectElements | Returns the user specified connected elements to be aligned with seed element

# Methods

Method | Description
--- | ---
AlignNormals | Aligns the normals of elements connected to the seed element.
Commit | Commits any edits that have been applied to the builder.
Destroy | Deletes the builder, and cleans up any objects created by the builder.
DisplayNormals | Display element normals for connected elements, which are to be aligned with seed element normal
FindAllVisibleConnectedElements | Finds all visible elements connected with the seed element
GetCommittedObjects | For builders that create more than one object, this method returns the objects that are created by commit.
GetObject | Returns the object currently being edited by this builder.
ShowResults | Updates the model to reflect the result of an edit to the model for all builders that support showing results.
Validate | Validate whether the inputs to the component are sufficient for commit to be called.

# Method Detail

## AlignNormals

`AlignShellElementNormalBuilder.``AlignNormals`

  Aligns the normals of elements connected to the seed element.

  Returns the elements that have had the normals successfully reversed. This method will only reverse the normals for shell elements in the current work fem part.

  Signature `AlignNormals()`

  Returns: |
  Return type: | list of `NXOpen.CAE.FEElement`

  New in version NX8.5.0.

  License requirements: nx_masterfem (“Finite Element Modeling”) OR nx_design_sim (“NX Design Simulation”)

## DisplayNormals

`AlignShellElementNormalBuilder.``DisplayNormals`

  Display element normals for connected elements, which are to be aligned with seed element normal

  Signature `DisplayNormals()`

  New in version NX8.5.0.

  License requirements: nx_masterfem (“Finite Element Modeling”) OR nx_design_sim (“NX Design Simulation”)

## FindAllVisibleConnectedElements

`AlignShellElementNormalBuilder.``FindAllVisibleConnectedElements`

  Finds all visible elements connected with the seed element

  Signature `FindAllVisibleConnectedElements()`

  Returns: |
  Return type: | list of `NXOpen.CAE.FEElement`

  New in version NX8.5.0.

  License requirements: None.

## Validate

`AlignShellElementNormalBuilder.``Validate`

  Validate whether the inputs to the component are sufficient for commit to be called.

  If the component is not in a state to commit then an exception is thrown. For example, if the component requires you to set some property, this method will throw an exception if you haven’t set it. This method throws a not-yet-implemented NXException for some components.

  Signature `Validate()`

  Returns: | Was self validation successful
  Return type: | bool

  New in version NX3.0.1.
