System defines an orthonormal, right-handed coordinate system.

A part can be associated to the system.

Example

from hwx import inspire

model = inspire.newModel()
block = model.createSolidBlock(location=(0, 0, 0))

# create a system
my_system = inspire.System()

# system has no part
print("Created one system and one block not associated")
print("My system part: " + str(my_system.part))
# block is at position (0,0,0)
print("Block position: " + str(block.location))

# attach system to block
my_system.part = block
print("")
print("System and block associated")
print("My system part: " + str(my_system.part))

# Do not move system with block
my_system.moveWithPart = False
print("")
print("Move system with part: " + str(my_system.moveWithPart))
print("Block position: " + str(block.location))
print("My system location: " + str(my_system.location))
print("Moving block...")
block.location = (1, 1, 1)
print("Block position: " + str(block.location))
print("My system location: " + str(my_system.location))

# Move system with block
my_system.moveWithPart = True
print("")
print("Move system with part: " + str(my_system.moveWithPart))
print("Block position: " + str(block.location))
print("My system location: " + str(my_system.location))
print("Moving block...")
block.location = (3, 3, 3)
print("Block position: " + str(block.location))
print("My system location: " + str(my_system.location))

inspire.fitView()

rotate(angle, axis='X')#

Rotate system along given axis at given angle.

Parameters:

angle (float) – Angle at which system is rotated.
axis (str) – Axis of rotation. - X - Y - Z

class SystemType(value)#

Bases: Enum

An enumeration.

`System`	`SystemType`

property active#

Returns or sets the object activeness.

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

destroy()#

Delete the object removing it from the model.

The object may come back due to an undo/redo.

getAllChildren(type=None, **kwds)#

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

Parameters:

type (list[Named]) – Filter to use to get the children based on object type.
**kwds – Additional keyword arguments to match other attributes of the object.

Returns:

The list of children that satisfy the supplied filters.

Return type:

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

getAttribute(name)#

Returns the Attribute off the class, not the value.

Parameters:: name (str) – Attribute name to find its class.

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

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

Parameters:

name (str) – The name of the child object.
recursive (bool) – Search all descendents.
**kwds – Additional keyword arguments to match attributes of the object.

Returns:

The child object which satisfies the specified filters.

Return type:

Named

getChildren(type=None, recursive=False, sorted=False, **kwds)#

Returns a list of children that is of the specified type.

Parameters:

type (Type[Named]) – Filter objects by class.
recursive (bool) – True to get all descendent Parts and Assemblies.
sorted (bool) – Sort the children base on id.

Returns:

list[Named]

getDependents(recursive=False, **kwds)#

Get objects that reference this object through a Reference attribute.

Parameters:

recursive (bool) –
**kwds – Filter objects using isa.

Returns:

set[Named]

getGuiValue(attr, **kwds)#

Get value formatted to be shown in the gui

Parameters:: attr (str) – Attribute name to gets its gui value.
Returns:: Returns a string of the value with its gui units, like “5 mm/s”.
Return type:: str

getReferences(recursive=False, **kwds)#

Get objects this object references through a Reference attribute.

Parameters:

recursive (bool) –
**kwds – Filter objects using isa.

Returns:

set[Named]

getValue(attr)#

Return the attribute value for passed attribute name.

Parameters:: attr (String) – Attribute name to gets its value.
Returns:: Returns the attribute value
Return type:: str

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

Determines if the object matches the specified settings or not.

Parameters:

type (Union[Part, Assembly, Contact..]) – The type of the object.
filter (method) – Return value of specified callback method.
name (str) – Name that matches exactly with object name.
wildcard (str) – A pattern to match exactly with the object name.
**kwds – Additional keyword arguments to match other attributes.

Returns:

True, if a match is found, otherwise False.

Return type:

bool

property location#: Origin of this system position as a Point.

modelPositions()#

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.

property moveWithPart#: Whether the system is moving with the associated part or not.

property name#

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.

property origin#: The origin of this system in local coordinate system.

property parent#

Returns the parent of this entity.

Type:: Assembly

property part#: The part associated with this system.

property position#: The global transform as a Matrix44.

setValue(attr, value)#: Alias for setattr (attr, value) :param attr: Attribute name to sets its value. :type attr: str :param value: Attribute value to set . :type value: str

setValues(**kwds)#

Sets passed name/value pairs.

Values are set in a standard order (the order the attribute is defined on the class) which is required in certain cases when an attribute’s setter expects another attribute to have already been set. For example, setting a reference before a location that is wrt it.

Parameters:: **kwds – Set attributes in one go.

property type#: The type of the system.

property visible#

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.

wasValueSet(attr)#

Check if attribute was set

Parameters:: attr (str) – Attribute name to check it value set or not
Returns:: True, if value was set else false.
Return type:: bool
