Amazing how this one slipped past me… Not even sure if this is only in 2015..

However, when you extract a feature line from a corridor. You can create a dynamic link back to the corridor (See below). That’s right… A “feature line” can be extracted from a corridor and when the corridor rebuilds, it updates itself!!

BUT WHAT IS SO AMAZING ABOUT THIS? …….well… CORNER OVERLAPS IN CORRIDORS CAN BE A LOT MORE DYNAMIC!!… read on below.

Say you have a tight corner in a corridor you can’t get away from..

Rather than extracting a feature line and having to move it every time your corridor updates..

You can now extract (tick the dynamic box).. create your grading… add it to your corridor surface.. but,,

Maybe I realign my corridor slightly. No problem.. The feature line and the associated grading goes with! Wonderful..
