Option

Description

Undo/redo buffers

Specifies the number of undo and redo buffers to allocate for each circuit window. Changing this option does not affect the currently open circuit windows; only new windows will make use the specified value. Almost all object manipulation functions (object create, delete, move, rotate, etc) can be undone (or redone). These functions also update the circuit's modified state to indicate that the circuit needs saving. During an undo operation, the modified state is reset its previous value, so if you undo the very first edit operation, the 'Modified' text in the status bar will disappear. Any operation undone can be redone. Since only a limited number of buffers are allocated, you are never guaranteed to undo all modifications. For example, if the number of undo/redo buffers are set to 10 (default) and eleven successive modifications to the circuit are made, the first modification can no longer be undone, and the modified state will not change until you save the circuit.

Background color

Selects the background color of circuit windows. The color list provides available system colors, but you may customize your own from the Windows standard Color dialog displayed by the Custom button. The current color selection is shown in the box to the right of the Custom button.

Background skin

The default skin is "Iceberg Classico" but ATPDraw also comes with the standard "Windows" option. There are problems with the standard Context menu (right click in standard dialogs) for skins different from "Windows".

Text editor program

Holds the name and path of the text editor program to use for editing ATP files (e.g. notepad.exe or wordpad.exe). If no program is specified (the field is empty), the built-in text editor is used. Note that the program specified must accept a filename on the command-line; otherwise, the ATP file will not be automatically loaded by the editor.

ATP program*

Holds the ATP program command. A batch file is suggested as default (runATP_G.bat or runtpd.bat for the Gnu versions). For the Gnu version, the ATP program can also be specified directly as %GNUDIR%TPBIG.EXE DISK $$ s -r  where $$ replaces the %1 sign normally used in a batch file. This requires the GNUDIR environment variable (for instance 'GNUDIR=c:\eeug\gnuatp\') to be specified in Windows. See also running ATP from ATPDraw.

ARMAFIT

program Holds the name of the Armafit program used for NODA line/cable models. A batch file runAF.bat is suggested.

Plot program*

Holds the name of the plotting program that can take the current PL4 file as input on the command line.

Run ATP window hidden

If checked, this will execute the solver (tpbig.exe) in a hidden command window. This will avoid flickering command windows in multi-run cases (combine with setting NODISK=1 in garaphics.aux for JMarti lines) as ATP will run silently in the background. This option must not be used if user interaction in a bat-file is expected (for instance 'pause') as this will cause the ATP process to 'hang'. The ATP Connection Wizard is the preferred method of controlling ATP execution.
