Assembly (hwx.inspire.core)

An assembly is a list of parts.

Assemblies can contain subassemblies, allowing you to organize your model hierarchically. Parts and subassemblies within an assembly are positioned in space relative to the parent assembly. If you translate or rotate a parent assembly, its parts and subassemblies move with it.

Assemblies do not have their own properties. Changing properties for an assembly actually applies the change to the individual parts within the assembly down to the lowest level in the hierarchy. Only properties common to all parts in the assembly are shown.

Public Methods

autoColorParts (self)

getCenterOfGravity (self, includeGround=True)

getFeatures (self, type=None, **kwds)

getMass (self, includeGround=True)

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.

autoCalculateCG : Bool

Determines whether the center of gravity is auto calculated.

autoCalculateMass : Bool

Determines whether the mass value is automatically calculated based upon volume and material density.

autoCalculateMoment : Bool

Determines whether the mass moment of inertia is automatically calculated.

cg : Location (units=”length”)

Returns the object’s global center of gravity as a point.

color : Color

Determines the color assigned to the object when it is displayed in the modeling window.

The default color for parts is gray, but a different color can be assigned.

detectCollisions : Bool

Determines whether to detect collision.

It prevents parts in the model from overlapping and has been enabled by default.

ground : Bool

Returns or sets the object to be ground or immovable.

ip : Inertia (units=”massMI”)

Specifies the inertial properties of this object.

Resistance to change in motion (ixx, iyy, izz, ixy, izy, ixz).

mass : Double (units=”m”)

The mass of the object.

material : Attribute

The material of the object.

Every part in the model has a material assigned to it. The default material is steel, but a different material can be assigned.

modifiable : Bool

Determines whether the selected object can be edited.

morphable : Bool

Determines whether the selected object shape can be changed.

movable : Bool

Determines whether the selected object can be translated in the modeling window or has been locked in place.

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.

position : Attribute

Specifies the global transform as a Matrix44.

transparency : Double

Specifies the transparency of the object.

Allows you to change the transparency, according to a percentage. By default, objects are 0% transparent(opaque).

visible : Bool

Determines whether the object is visible in the modeling window.

Setting this on or off sets all children. Setting to True sets all the parents visible too.

volume : Double (units=”volume”)

The volume of the object in the assembly.

Property Details

assemblies()

Returns a list of assemblies.

features()

Returns a list of all features from the parts in the assembly.

loads()

Returns a list of all the loads (Constraint, Force, Torque, …) in the assembly.

parts()

Returns a list of all the parts in the assembly.

rigidGroups()

Returns a list of all rigid groups in the assembly.

sketches()

Returns a list of all the sketches in the assembly.

Method Details

autoColorParts(self)

Automatically assigns different colors to all the parts in the assembly.

getCenterOfGravity(self, includeGround=True)

Returns the centre of gravity of the assembly.

param includeGround:  Includes non-grounded parts. type includeGround:  bool returns:The centre of gravity of the assembly. rtype:Point

getFeatures(self, type=None, **kwds)

Returns all features that matches the specified filters.

param type:The type of features to return. type type:Union[FeaturePoint, FeatureArea, FeatureCylindrical, …] param **kwds:Additional keyword arguments to match other attributes. returns:A list of features that satisfies all the filter criteria. rtype:list [Union[FeaturePoint, FeatureArea, FeatureCylindrical, …])]

getMass(self, includeGround=True)

Returns the mass of the assembly.

param includeGround:  Includes non-grounded parts in mass calculation. type includeGround:  bool returns:The mass of the assembly. rtype:float
