I use to be able to explode text in 2011 but the txtexp command does not work any more,  How do you creat 3D solids from text now if you cant explode and push/pull to generate the solid?

If you'r interrested, I've loaded a file with 3D letters and numbers "ABCD.dwg".
 
I use it in my 3D drawings that I transfert to "SOLIDWORKS" because in the convertion the texts don't go to "SOLIDWORKS".
 
I think that I've already seen a cad discussion about this and the solution was to save the file ( beware to save a copy and not the original ) to the Release 12 ( to be confirmed ).

Did the command work at one time then stop functioning?Is Express Tools loaded?
