RigidGroup (hwx.inspire.core)¶
Group of parts which don’t move relative to each other and are realized to motion as a single rigid body.
Rigid groups are mutually exclusive meaning a part can’t be in two at the same time.
Attributes¶
Public Methods¶
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.
ground : Bool¶
Returns True, if any of the rigid group parts are grounded.
ip : Inertia (units=”massMI”)¶
mass : Double (units=”m”)¶
Returns the combined mass of all the parts in rigid group.
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.
parts : Attribute¶
List of parts in the rigid group.
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.
Property Details¶
-
cg()
Returns the center of gravity point of the rigid group.
-
position()
Returns the position of the first part as a Matrix44.
