Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Package Parts contains rigid components of a multi-body system. These components may be used to build up more complicated structures. For example, a part may be built up of a "Body" and of several "FixedTranslation" components.

ModelDescription
Fixed Frame fixed in world frame at a given position. It is visualized with a shape, see shapeType below (the frames on the two sides do not belong to the component):

FixedTranslation Fixed translation of frame_b with respect to frame_a. It is visualized with a shape, see shapeType below (the frames on the two sides do not belong to the component):
 
model Parts.FixedTranslation
FixedRotation Fixed translation and fixed rotation of frame_b with respect to frame_a It is visualized with a shape, see shapeType below (the frames on the two sides do not belong to the component):

Components Fixed, FixedTranslation, FixedRotation and BodyShape are visualized according to parameter shapeType, that may have the following values (e.g., shapeType = "box"):
 

model Visualizers.FixedShape

All the details of the visualization shape parameters are given in Visualizers.FixedShape

Colors in all animation parts are defined via parameter color. This is an Integer vector with 3 elements, {r, g, b}, and specifies the color of the shape. {r,g,b} are the "red", "green" and "blue" color parts, given in the ranges 0 .. 255, respectively. The predefined type MultiBody.Types.Color contains a menu definition of the colors used in the MultiBody library (this will be replaced by a color editor).
