Salut,

Je cherche à faire un "retour état initial" dans un code, mais à part

(vla-startundomark (vla-get-activedocument (vlax-get-acad-object)))
.....................le prog....................
(command "_undo" "_back")

Je ne vois pas comment faire....

for last version autocad, to *error* program:

(vla-SendCommand (vla-get-ActiveDocument (vlax-get-acad-object)) (strcat (chr 27)(chr 27)"_.undo 1 "))

Hi Alexander,

 

This is very strange - the *error* function no longer appears to support the use of (command) (whether on its own or with arguments). I have submitted a change request for this functionality.

 

In the meantime, you can use a workaround as show in the attached file, using COM functions to call the commands you wish. It's not ideal, as these strings do not then respect CMDECHO, but it does function as you'd expect:

 

(vla-SendCommand (vla-get-ActiveDocument (vlax-get-acad-object)) (strcat (chr 27)(chr 27)"_.undo _e _.u "))
