Joints:
Joints are objects of submodels becoming exported into the parent model.
Joints using the code letter J.
  
Applications for Joints:

  Assemblies, Schematics (electrical, hydraulic, pneumatic)
       Importing points as connecting points (example)
       Import a reference-system (plane) for positioning a submodel.
  
  Kinematics

  Animation paths, Camera Drives
    NOT YET IMPLEMENTED.
  





Joints on points:

  The corresponding object (point or plane)  is created automatically
    when inserting this model as external submodel -
    the object is imported in the parent model.
  Example:
    The current model is an electrical resistance;
    the connection points are defined as joints.
    When inserting the resistance as a submodel the
    Connection points automatically generate normal points.
    See sample_DiagEl1.gcad model.
    
# Export:
J1 = P20    # export point in subModel

# Import: (is created automatically by import of external submodel as M20)
P20=IMP M20 J1   # import Joint Nr.1  from subModel M20


Example:
- create model with points to connect (eg my_jnt1.gcad):
  - create a rectangle, create the connection-points
  - set the connention-points as JOINTS: 
    CAD create joint-export, sel point ..
  - store model as eg my_jnt1.gcad

- create model using external connection-points (eg my_jnt2.gcad):
  - load model with connection-points (eg my_jnt1.gcad)
    CAD Submodel "M external Model" my_jnt1.gcad, set position, OK.
    The connection-points have been created automatically - see MAN
  - the connection-points can be used as normal points ..
  - store model as eg my_jnt2.gcad

CAD-Functions Joints:



Joint-export
 Export the selected object of the current model as a joint.

   joint-object       select point or plane


Output:
J1 = P20
