I've been looking all over for an axl function to delete a subclass - but I've not been able to find such a function.
Can anyone help me?
axlDeleteObject - assumes layer is empty and not a pre-defined Allegro subclass (e.g. can't delete ETCH/TOP)
Example if you want to delete a user subclass named "FOO" on board geometry
p = axlLayerGet("BOARD GEOMETRY/FOO")
In reply to fxffxf:
Thanks that just what I needed
What if I want to delete BOARD GEOMETRY/BOTH_ROOMS or MANUFACTURING/NO_PROBE_TOP since those subclasses are unused? I'd like to eliminate unneeded layers to clean up the DB, instead of having "wasted" layers in my company's otherwise streamlined and customized default boards. There's really no way to eliminate pre-defined subclasses?
In reply to EvanShultz:
To anyone else looking for confirmation, the answer is no. Pre-defined subclasses are there to stay, an AE tells me.
I'm trying to find out a method of removing all un-used subclasses (not the predefined subclasses).How do we iterate through all the custom subclasses and how do we find out if its is empty or not?
Regards,Vijay Anandh Vela, CID
In reply to VijayVela:
Use axlSubclasses to list all subclasses for a class.
Use axlLayerGet to get the layer parameters. The userDefined attribute tells you whether it is user-defined
Use the selection set utilities to see if it's empty

Hi Dave,Thanks for the guide. I managed to write a SKILL program to do this. One of my first program.. I'm pretty sure this code can be further simplified so realy appreciate your comments. Below is my code:-
defun( cleanupSubclass () l_sclass_to_delete = tconc(nil "SMART") l_filter = list("noall" "lines" "shapes" "linesegs" "shapesegs" "voidsegs" "figures" "text") l_visibility=axlVisibleGet() ;To store the currnet visibility axlSetFindFilter(?enabled l_filter ?onButtons l_filter)
foreach( _subclass axlSubclasses("PACKAGE GEOMETRY" ?field 'userDefined) ;Check every user defined subclass axlClearSelSet() axlVisibleDesign(nil) axlVisibleLayer(strcat("PACKAGE GEOMETRY/" _subclass) t ) axlUIWUpdate(nil) axlAddSelectAll() aChkEmpty = length(axlGetSelSet())
if( aChkEmpty > 0 then ; DO NOTHING AS THE SUBCLASS IS NOT EMPTY else if( substring(_subclass 1 3) == "DTS" then ; do nothing is there is a DTS prefix which is being used in our process else ;APPEND THE CLASS/SUBCLASS INTO THE LIST scls = strcat("PACKAGE GEOMETRY/" _subclass) tconc(l_sclass_to_delete scls) ;append it into a list in the <class/subclasss> format ) ;end if ); end if );end foreach
axlClearSelSet() axlSetFindFilter(?enabled 'noall ?onButtons 'noall) deleteUnusedSubclass(cdr(car(l_sclass_to_delete))) axlVisibleSet(l_visibility) axlUIWUpdate(nil)
) ; end defun
defun( deleteUnusedSubclass (l_delSubCls) foreach( sclsToDelete l_delSubCls ;delete every user defined subclass which are empty axlDeleteObject(axlLayerGet(sclsToDelete)) );end foreach text items
); end defun
This is somewhat simpler:
defun( cleanupSubclass ()
let((l_filter, l_visibility, layerName)
l_filter = list("noall" "lines" "shapes" "linesegs" "shapesegs" "voidsegs" "figures" "text")
l_visibility = axlVisibleGet() ;To store the currnet visibility
axlSetFindFilter(?enabled l_filter ?onButtons l_filter)
foreach( _subclass axlSubclasses("PACKAGE GEOMETRY" ?field 'userDefined) ;Check every user defined subclass
axlVisibleLayer(strcat("PACKAGE GEOMETRY/" _subclass) t )
unless(axlGetSelSet() || substring(_subclass 1 3) == "DTS"
;Delete the layer
layerName = strcat("PACKAGE GEOMETRY/" _subclass)
when(axlUIYesNo(sprintf(nil, "Delete layer: %s", layerName), nil, 'no)
axlDeleteObject( axlLayerGet(layerName) );add it into a list in the <class/subclasss> format
) ;end unless
axlSetFindFilter(?enabled 'noall ?onButtons 'noall)
)) ; end defun
