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.

Property Details

property axis

Line segment through the centre of holes where parts are connected.

There are 2 points for each part.

property direction

Specifies which side of the hole, the screw will enter and exit.

Usually set to the direction of the view at creation.

property features

List of features making up the holes.

property location

Returns a Point either defined from the connector’s axis, if it exists, or the location of the first feature or, if no features available, a Point at [0, 0, 0].

property parts

Returns a list of connected parts.

property partsInHoles

CAD parts this connector replaced at creation.

property radius

Radius of the cylindrical shaft.

This is typically equal to the radius of the smallest hole the fastener goes through.

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..]

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)

Returns a list of all children that matches the specified type.

param type

Filter to use to get the children based on object type.

type type

list[Named]

param **kwds

Additional keyword arguments to match other attributes of the object.

returns

The list of children that satisfy the supplied filters.

rtype

list[Union[Part, Motor, BoundaryCondition, …]]

getAllowedTypes(self)

Returns a list of allowed part connectors type.

returns

List of allowed part connectors.

rtype

list

getChild(self, name=None, recursive=False, **kwds)

Returns the child of the object which matches the specified unique name.

param name

The name of the child object.

type name

str

param recursive

Search all descendents.

type recursive

bool

param **kwds

Additional keyword arguments to match attributes of the object.

returns

The child object which satisfies the specified filters.

bool

param sorted

type sorted

bool

returns

list[Named]

getDependents(self, recursive=False, **kwds)

Get objects that reference this object through a Reference attribute.

param recursive

type recursive

bool

param **kwds

Filter objects using isa.

returns

set[Named]

getReferences(self, recursive=False, **kwds)

Get objects this object references through a Reference attribute.

param recursive

type recursive

bool

param **kwds

Filter objects using isa.

returns

set[Named]

isa(self, type=None, filter=None, name=None, wildcard=None, **kwds)

Determines if the object matches the specified settings or not.

param type

The type of the object.

type type

Union[Part, Assembly, Contact..]

param filter

Return value of specified callback method.

type filter

method

param name

Name that matches exactly with object name.

type name

str

param wildcard

A pattern to match exactly with the object name.

type wildcard

str

param **kwds

Additional keyword arguments to match other attributes.

returns

True, if a match is found, otherwise False.

rtype

bool

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.
