Fastener (hwx.inspire.core)¶
Fasten two or more parts together.
Fasteners connect parts together without allowing movement at the hole location.

Attribute Details¶
active : Bool¶
Returns or sets the object activeness.
Setting this on or off sets all children. Setting to True sets all the parents active too.
autoCalculateAllowableForces : Bool¶
Determines whether the allowable axial and shear forces will be manually added.
axialForce : Double (units=”force”)¶
Manually entry of the Allowable Axial Force.
Based on the yield stress and the area of the hole Inspire automatically determines the maximum stress allowed for the fastener or cylindrical hole support, if autoCalculateAllowableForces is set to True.
axialStiffness : Double (units=”stiffness”)¶
The spring stiffness in the axial direction.
color : Color¶
The color assigned to the connector when it is displayed in the modeling window.
connectionRadius : Double (units=”length”)¶
The search radius for the connector.
enableAllowableForces : Bool¶
Determines whether to enable optimization of the selected fasteners or cylindrical hole supports.
enablePretension : Bool¶
Determines whether pretension is enabled.
If pretension is enabled and defined, the pretension is then included as a load in all load cases.
featureLists : Attribute¶
A nested list of features making up the holes.
grounded : Bool¶
Determines whether the connector is grounded.
material : Attribute¶
The material of the connector.
name : Attribute¶
Returns or sets the name of the object.
It can be any text string, including spaces, although it’s best to avoid using the following characters: ” ‘ * ? and $.
While these characters are allowed, they could create difficulties when you export the model to other applications.
pretensionForce : Double (units=”force”)¶
The magnitude for the pretension force.
Applying pretension to bolted and screwed connections allows a more complete understanding of the behavior of a structure. Often, these preloads are of a significant magnitude and can influence design decisions.
Typical examples are clamping structures, such as bearing housings or bicycle handlebars and seat-posts. In engines, cylinder bore distortion can be a critical design requirement highly influenced by the loads generated by the bolt down of the cylinder head.
shearForce : Double (units=”force”)¶
Manually entry of the Allowable Shear Force.
Inspire automatically determines the maximum force allowed for the fastener or cylindrical hole support, if autoCalculateAllowableForces is set to True.
shearStiffness : Double (units=”stiffness”)¶
The spring stiffness in the shearing direction.
type : Enum¶
The type of the connection.
Call getAllowedTypes to see which are the allowed types.
visible : Bool¶
Determines whether the object is visible in the graphics window.
Setting this on or off sets all children. Setting to True sets all the parents visible too.
Method Details¶
- classmethod getClass(cls, className)¶
Returns the class of the object.
It can be simple or qualified (with namespace). If the name is simple, we prepend the cls.namespace.
- param className
The class name.
- type className
Union[Part, Occurrence, Named..]
- returns
The class for the specified className.
- rtype
Union[Part, Occurrence, Named..]
- __new__(cls, connection=None, direction=(0, 0, 1), name='', **kwds)¶
Create and return a fastener.
Fasteners connect parts together without allowing movement at the hole location.
- param connection
A list of list of features. Usually a holes instance.
- type connection
list
- param direction
Specify fastener’s head direction.
- type direction
tuple
- param name
Name to the fastener.
- type name
str
- param **kwds
set any other property, like color=”green”.
- returns
Return created fastener.
- rtype
Fastener
- destroy(self)¶
Delete the object removing it from the model.
The object may come back due to an undo/redo.
- getAllChildren(self, type=None, **kwds)¶

- getAllowedTypes(self)¶
Returns a list of allowed part connectors type.
- returns
List of allowed part connectors.

- modelPositions(self)¶
Forces all objects to return the original model positions instead of the current analysis positions.
Useful when defining draw methods on GeneralObjects where behaviour is different while animating.
