For those using ACAD Lt  2015.   Are there many improvements over theolder versions  (Say  ACAD Lt  2009).The command  (MOCORO)  (move-- copy--rotate) meaning to copy and rotatemultiple times I believe is available in the full version of ACAD. Is this command (or an equivalent) available in ACAD Lt  2015 ?Thanks in advance,  H. Hampton.

Yes, there are many improvements.  After all, that constitutes a six year span!
