Microstation V8i Clash detection question

Question

Hi all, 
 Im setting up a big clash detection file in Microstation V8i - its roughly 25 models clash checking with one another. 
 We are generating around 5000 individual clashes which need to be assigned to the relevant people. 
 I expected a lot, but this is going to take a huge amount of manual work to get through. 
 One thing that we have seen is that many of the clashes are very, very small, say elements which are 1-2mm clashing with one another. 
 What I wanted to do was set a 'negative soft clash' - an acceptable limit for elements to clash with one another - say for example 5mm. 
 I know that you can set a soft clash which will flag up if elements are a certain distance apart - but struggling hugely to find if this is possible the other way around. 
 Im sure it must be something to do with the rule bases - but cant make heads or tails of it. 
 Many thanks, Peter

Hi Peter, 
 The rules work best for eliminating clashes based on item properties. For example if you found that you had a lot of clashes caused by equipment that was set 1mm below floor level you could set up a rule to ignore any clashes between equipment and floors. That really depends on what type of clashes you are seeing and which ones are the important ones for you. Hope that helps.
