% Build a model of a spacecraft using repeated calls to this function.
A GUI displays the results. It is not designed to allow you to interactively
modify the design. With no inputs it returns a list of actions. All 'add ...'
require data and most return an index to the new body or component(s).
The basic structure of a script using BuildCADModel is
BuildCADModel('initialize',...)
kBody = BuildCADModel('add body',...)
BuildCADModel('compute paths') % once all bodies are added
kComp = BuildCADModel('add component',...)
BuildCADModel('add subsystem',...)
BuildCADModel('set external model',g)
g = BuildCADModel( 'get cad model' )
BuildCADModel( 'show vehicle' )
The mass properties for the spacecraft may either be set manually or
computed from the mass properties of the components. To set them
manually, enter:
BuildCADModel('set mass',mass);
where mass is a struct with fields mass (scalar), cM (3x1 vector) and
inertia (3x3 matrix). The mass properties are otherwise automatically
updated when the model is retrieved or saved. To command an update, enter:
BuildCADModel('update spacecraft mass properties');
If the mass properties are set manually, they are considered "locked",
and they cannot be overwritten by an automatic update until they are un-
locked. To lock or unlock the mass properties at any time, enter:
BuildCADModel('lock mass properties');
-or-
BuildCADModel('unlock mass properties');
When adding components to subsystems pass in their names, as well as
the name of the subsystem. The exact name is not required, i.e.
'thruster' for Thruster 1, Thruster 2, etc.
BuildCADModel('add subsystem','subsys name',{'component 1','component 2'})
In order to perform shadowing calculations on the model, you need to
explicitly generate the body-level lists vertices and faces after all the
components have been added.
BuildCADModel('create body arrays')
