what is clash detection
_____________________________________________________________________________________. Clash Detection-Clash detection is an analytical tool which automates the clash detection process. The clash detection feature allows you to identify sets of business or graphical elements and to detect geometrical clashes between these object element sets. You can then interactively and graphically review these clashes, annotate or markup particular clashes, and assign them for follow-up.
Utilizing laser scan data for clash detection is a very cost-effective method because it reduces change orders, field re-work, and schedule delays due to clashes that would have otherwise gone undetected.
