The model I'm running clash detection on has component models from many different people and authoring programs and includes both NWD and IFC models. Creating sets to use for clash detection has been a challenge because many of the systems' components I need to test against each other are all mixed in the same model as other things without sub-groupings (or unhelpful sub-groupings), so finding a property to do an efficient search can be difficult, if not impossible (meaning I have some criteria that are just the GUID for a single item).
That brings up issues that can be a whole other topic, and not what I'm asking about here. What I want to find out here is if it's better (easier/quicker for Navisworks to process) to have one large search for everything I need to test a system, or is it better to have several smaller searches, since I can select multiple search sets in Clash Detective?
For example, a single search set that includes all plumbing items I want to test, versus 2, 3, or 4 smaller search sets that would each search more specifically...something like "Plumbing - Trade Pipes & Fixtures," and "Plumbing - Design Pipes & Fixtures," etc. that might only have 4 or 5 criteria each.
A "large" search in this case has ~30+ criteria, mostly "OR" conditions, with a few "AND" & "Negate" conditions as well. I ask because I've noticed that it can take a couple of minutes for Navisworks to run these large searches.
