Pack the macros for the components in an include file. Include required 
informations inside that include file.

Some components may best be modeled as meshes: ex.: fins.
Any part with linear sides can be modeled as cylinders and cones. This include 
the main parts as airframe, couplers, nose cones and size reducers/expanders.
Make all parts lined up along a specific axis. Have all parts expand from a 
common plane: base situated at <0,0,0> and expanding toward +Y.
