Collision Detection in NavisWorks

Here's a few images of some collisions I found on a small project we're working on.
It was extremely easy to convert and import the files into NavisWorks, took about 10 minutes and this was my first go at it!
This was simply checking Mechanical against Structural, the collision detection runs so fast it's ridiculous. In Revit this would have taken an hour.
Next step is to learn TimeLiner
