Some new ones I am finding the past few days that are pretty critical:
(command "ANNOTATIVEDWG" 0)
; Specifies whether or not the drawing will behave as an annotative block when inserted into another drawing
; 0 Nonannotative
; 1 Annotative
; Note The ANNOTATIVEDWG system variable becomes read-only if the drawing contains annotative objects.
; (princ "\n")
(command "ANNOAUTOSCALE" -4)
; Updates annotative objects to support the annotation scale when the annotation scale is changed.
; When the value is negative, the autoscale functionality is turned off, but the settings are maintained:
; 1 Adds the newly set annotation scale to annotative objects that support the current scale except for those on layers that are turned off, frozen, locked or that are set to Viewport > Freeze.
; -1 ANNOAUTOSCALE is turned off, but when turned back on is set to 1.
; 2 Adds the newly set annotation scale to annotative objects that support the current scale except for those on layers that are turned off, frozen, or that are set to Viewport > Freeze.
; -2 ANNOAUTOSCALE is turned off, but when turned back on is set to 2.
; 3 Adds the newly set annotation scale to annotative objects that support the current scale except for those on layers that are locked.
; -3 ANNOAUTOSCALE is turned off, but when turned back on is set to 3.
; 4 Adds the newly set annotation scale to all annotative objects that support the current scale.
; -4 ANNOAUTOSCALE is turned off, but when turned back on is set to 4.
(command "ANNOALLVISIBLE" 1)
; Hides or displays annotative objects that do not support the current annotation scale.
; The ANNOALLVISIBLE setting is saved individually for model space and each layout.
; Note When ANNOALLVISIBLE is set to 1, annotative objects that support more than one scale will only display one scale representation.
; 0 Only annotative objects that support the current annotation scale are displayed
; 1 All annotative objects are displayed
(command "PEDITACCEPT" 1)
; Change splines to plines using PEDIT
(command "savefidelity" 0)
; Horrible Annotation Scales system variable that can ruin projects:
; do not turn on unless you want to reiterate through every anno scale
; of every xref nested over and over again causing load time to seem like your workstation is locked up.
(command "XFADECTL" 0)
;Turns off XREF Fade controls - Settings are 90 through -90
; (princ "\n")
(command "XDWGFADECTL" 0)
;Turns off XREF Fade controls - Settings are 90 through -90
