question about the delete subclass

Dear all, It's my first time for asking help here about a skill. I want to write a function about the class/subclass modify and update. 1,if the Old_Drawing_1 is exist and drawing is not null. I need delete all the Old_Drawing and change the drawing_1 to Old_Drawing_1 But When I want to use the axlDeleteObject function, it said that if the drawing is not null,it can not delete it, and I don't want to use the axlshell delete function. 2, also I found a question about the delete;when I use the delete Symbol "Drawing_name" done, I can not delete, but when I use to other normal symbol. such as U1.it works! 3,In a word, Just done: 1,Drawing_i-->Old_Drawing_i (i=1,2,3,4...) 2,intellect judgement and update.(Notes: Drawing1&Drawing2 or Drawing3&Drawing4 is a symbol load by bsm file) thank you!

sorry Dave,
Old_Drawing_id such as "BOARD GEOMETRY/Old_Drawing_1"
it is a class/subclass, also a symbol (mechanical symbol).I place it as a bsm file into the board.
maybe the question should be: how to judge the drawing layer belong to which mechanical symbol?
thank you!

Cadence doesn't work like that. Layers do not "belong" to symbols. So there is no Class/Subclass, as such, for a symbol.

If you have a mechanical symbol placed that only has objects on one layer you can use the method that I described earlier to detect that layer. i.e. get the layer(s) of the children of the symbol.
