Maybe this can help too: http://gdl.graphisoft.com/reference-guide/parameters-for-labels
Label orientation can be disabled with AC_DisableLabelOrientationVal
Sizes can be disabled with lock ‘A”, “B”
Uniform pen and pointer on/off can’t be disabled.
Hiding/locking AC_LabelPointerPen, AC_LabelPointerLineType, AC_LabelPointerConnection isn’t useful, they are still accessible in the infobox.
Pointer connection can be forced using ac_bCustomPointerConnection and placing the hotspots 1-3-5 and 2-4-6 in the same place.
