Hi DesuDeus, also one other note on clines - it is actually possible in MoI to set up clines that stick around by setting up a plugin or using some keyboard shortcut scripts.

There is a plugin available here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=1029.1
that will set up a custom command that lets you draw clines that stay until you clear them.

Also you can set up a keyboard shortcut with the script mentioned here:
http://kyticka.webzdarma.cz/3d/moi/#KeepCLine
which will let you set up a key that will keep the clines that you created during a command rather than letting them get erased as they normally do.

If you'd like some more flexibility with clines right now, you might want to set up one or both of those to get some additional functionality in the current version.
