    Problems with refdes assignment

    guido.kneis

      Hello,

      first i must admit i am pretty new to dxdesigner and havn't had proper training yet.

      But i have to get on with the design right now

       

      So right now i got stuck in automatic refdes assignment.

      All components in the schematic are set to "?" (R?, C? etc)

      I choose Tools -> PCB interface -> process to run: Assign Reference Designator

      On the top of the schematic page there is a message popping up:

      "schematic is in readonly mode" and it doesn't assign refdes.

      But i am the only one working on the design.

      So what is going wrong here?

       

      thanks in advance
