A possible next step would be to also support the Line Model Frequency Scan for verification of the correctness of the line cable model V CONCLUSION ATPDraw is continuously developed and the new facilities added since June 1997 are mainly improved handling of MODELS direct execution of external programs like ATP new and more powerful components and a User s Manual On the schedule are further improvements in handling of MODELS and inclusion of Line Cable modelling in ATPDraw by support of Cable Parameters APPENDIX ATPDraw functionality The appendix lists some of the functionality in ATPDraw Much more information is found in the User s Manual 3 Fig 13 shows the main window in ATPDraw with some Open circuit windows and the Selection menu to the right ADP Dray Be Edi yea AIF Qbewis Took window Halo OaS iS as Salen IS Sjal IP a oA vty 1 H m leaned oF ous US vahend Line PCH AL Phi Ta es Aij MODE ELIT Fig 13 ATPDraw main window From the Selection menu the user selects components to insert into the circuit This menu pops up when clicking the right mouse button in an empty area of a circuit window To select and move an object simply press and hold down the left mouse button on the object while moving the mouse Release the button and click in an empty area to unselect and confirm the new position The object is then moved to the nearest grid point 10 pixels resoluti
