Assembly (hwx.inspire)#

class Assembly(parent=None, **kwds)#

Bases: Occurrence, Primitives

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.

Method Table#
Name	Description
`autoColorParts` (self)	Automatically assigns different colors to all the parts in the assembly.
`destroy` (self)	Destroys assemblies from the model.
`getCenterOfGravity` (self, includeGround=True)	Returns the centre of gravity of the assembly.
`getFeature` (self, name=None)	Find feature by its __str__/__repr__.
`getFeatures` (self, type=None, **kwds)	Returns features that matches the specified filters.
`getMass` (self, includeGround=True)	Returns the mass of the assembly.
`save` (self, file)	Save the Assembly in the specified file.

Example

from hwx import inspire
from hwx.common import math

model = inspire.newModel()
assem = inspire.Assembly()
block = assem.createSolidBlock(position=math.Matrix44(origin=(-2, 0, 0)))
cyl = assem.createSolidCylinder(radius=.5)
sphere = assem.createSolidSphere(radius=.5, position=math.Matrix44(origin=(2, 0, 0)))
print("origin.y's:", block.position.origin.y, cyl.position.origin.y, sphere.position.origin.y)

# Move all of the above parts together
assem.position = math.Matrix44(origin=(0, 2, 0))
print("origin.y's:", block.position.origin.y, cyl.position.origin.y, sphere.position.origin.y)
inspire.fitView()
