Hello, 1/i read here and see that most of method for Node::Model has been deprecated. How node object is definited in OS ?

2/how we determine node name (node object) of assign setpoint manager to a defined (added to airloop/waterloop) straight component like cooling coil, fan, VAV box, etc ?

3/ Have any method to get string directly from text object in .OSM similar to object.setString(number of line," content") ?
