Hi Gertwin,
I made some modification at the command PyCadBaseCommand ..
now it support messages ..
so the code in the below mail is wrong ..
use this instead:
cObject=self.__pyCadApplication.getCommand(cmd_Key)
for iv in cObject:
exception,message=iv #Now the iv contain a tuple with
exception + message
try:
raise exception(None)
except ExcPoint:
cObject[iv]=self.imputPoint(message)
You can find this modification at the last git push
I will be out of the net for the Easter period .. till 7-8 April ..I
wish you All (PythonCad Team ) a good Easter and all the best for your
family too.
Regards,
Matteo
