VituixCAD - How to align woofer/tweeter measurements via delay?

Thank You!
I will read everything I can. Kimmo's description of using REW and VCD. REW's instruction manual and a bunch of stuff from Reid Towsley. (by the way, I use ECM8000 for measurements (possibly Dayton EMM-6) and Roland Rubix 24 USB audio interface, with normal-semi dual connection.)
