The Set Symbology option sets the active MicroStation symbology (level, line weight, line color, line style) to the default symbology values of the selected PE-HVAC symbology definition. For example, before you create a device cell, set the active symbology to device. You can also use this command if you want to place a MicroStation object in your design file using PE-HVAC symbologies for the object.
