Extracting cracks in rigid concrete pavement

Hello all. 

I am having trouble locating rigid concrete pavement deficiencies in my point cloud.  I am only able to identify roughly 90% of cracks in my concrete that I can see from my imagery.  I am using OpenRoads designer to analyze my point cloud.  My question is this: Is ORD powerful enough to do such analysis or should I learn how to use Topodot?  I don't know if I am using ORD to its full potential or if it simply is not built to do such analysis. 

Thanks all
