[Therion] drawing map over xvi: best practices requested

[Vasily Vl. Suhachev]

Hello

Possible two workflow for drawing map over xvi:

First:
1) integrate new centerline in whole cave (loops closed)
2) process whole cave and export xvi
3) draw over xvi
2) process map

Second:
1) process only new centerline and export xvi (no loops)
2) draw over xvi
3) integrate new centerline in whole cave (loops closed)
4) process map

Pros/Contras for each approach? Maybe possible another right way?
