addition of components

purikku22

we had finished a design and after the power simulation, the customer wanted to add some demitas capacitors. the customer only provided the new netlist ( which includes the new nets). how can i add the components on the board? i tried the copy (symbol) but i cannot add refdes to the components (it says that refdes is not available). what will i do to add refdes? I cannot do a successful Net import without assigning the new components first.im using Allegro PCB Perfomance Option L 15.7. what should i do?

 regards,

eric

    Try adding the components from the menu path

    Logic - Part Logic

    In the main section of the form, select the device you want to copy then backspace the current Ref Des List and add a string of new caps (ex C100-150)

    edhickey thanks. i successfully added the capacitors. but my problem now is the net import. the capacitors are declared already in the netlist, but after importing the cpacitors dont still possess the net. what could be the problem now? eg. C270 (this is the net file)
