I guess it does not exist. I have spent lots of time searching for how (if possible) to import
an excel (XLS or CSV) back to CTB.
I exported three CTBs to excel, edited them how I would like them (CTBs) to be, now I would
like to find any possible method of importing them back into a CTB file - am just lazy to change
my CTB in AutoCAD, one line by one line. Don't think I have a choice than to do all 255x3 lines
one by one.
Thanks.
