ConvSEO does not offer any built-in collision commands of its own. However it does break the SketchUp model up into individual objects which can be used easily with the DBPro built-in collision commands (as demonstrated in the included viewer program). I am not an expert in this area but I think you should be able to use any object-based collision scheme that you would otherwise use with any other collection of objects.
Hope this helps.
