Hello Alex,
From Piping Help file:
The color table is initialized by reading COLOR.INI and the values are stored in the ACAD dictionary. As new values are found they are added to the dictionary.
These functions view/reset the color table in the dictionaries.
(at_PipingSystemColorTable_display) ; displays color table in text window
(at_PipingSystemColorTable_reset) ; reads in CONFIG.INI and updates values. Values that are in the existing dictionary, but not in the INI remain.
Note: Redraw after a change to update the color of the components.
So in case the DWG file was created before CONFIG.INI file was modified, use (at_PipingSystemColorTable_reset) command to update ACAD dictionary.
As for (at_PipingSystemColorTable_display) , some time it is necessary to increase AutoCAD Text windows line number. Please use this command to achieve this: (setenv "CmdHistLines" "1000") it will increase displayed lines number to 1000.
I hope this will help.
Regards,
Artiom
