    Default Selection Set issues

    OK, so I have a BIG NW Model, well over 300 xrefs attached, 60 batches, 80+ rules and I'm trying to make a rule to run clashes between objects that are identified by a layer modifier.

    The layer modifier is to help distinguish between the layers we're using and the layers provided to us by another site.

    So, I've been working on a selection set and here's what I have.

    This is a Negate Condition.

    Category = Item
    Property = Layer
    Condition = Contains
    Value = F42 < that being the layer modifier.

    I'm also attaching a .jpg to show you what it looks like.

    I've made a rule that simply say anything that doesn't have the F42 Vs Anything that doesn't have the F42 should be ignored.

    When I run my clash report, it still shows the non-F42 layers vs non-F42 layer clashes.

    Anyone have an idea??

    Can you show the entire Find Items window pane?

    I've got a few guesses, but its possible that this will help. When I've set up sets in the past, I would create a search set for Mechanical, then search sets which further refine the Mechanical set.
    As an example, my Mechanical Pipe set searches through all files in the model for the MP string.
    The Piping/Equipment set searches through ONLY the Mechanical Piping search set, and Negates specific layers. In order for this to work, I had to add extra (redundant) string which first looked for a file name containing the MP string.

    You could also create a high level search set, which identifies all F42 files, and refine from there.

    OK, I'm attaching a little more info on my selection set issue as requested.

    You'll notice on the right side of the screen, there's a second screen shot pasted in to the first part with the Find Items. That's showing the rule that was created and there's also the result from the clash report showing the rule isn't working..

    Modify your search set.
    Add this:

    Category = Item
    Property = File Name
    Condition = Contains
    Value = DM.dwg

    Then negate this one.

    Category = Item
    Property = Layer
    Condition = Contains
    Value = F42

    Make sure that Prune Below Result is selected, and search set as Default.

    You may have to create a new search set for it to work, I've been driven to many hours of drinking trying to sort these out; even with all settings as they should, sometimes the set won't work until you create a fresh one.

    I thought about the positive before the negative side of things.. I think I might have tried it but, I went ahead and did it the way you mentioned, even created a new set.

    Here are the results.

    Under XX3EE2-1-603-F4-DM.DWG you can see a lot of F42 and non-F42 layers, none of which are highlighted. It looks like it went through and selected the first part but, didn't negate the second part of the set criteria.

    What I need the set to do is if there's a clash between say E-POWR-DEVC and E-POWR-IDEN, it doesn't show in my report.

    If it has a clash between E-POWR-DEVC and E-POWR-IDEN-F42, it will show in my report.

    If it has a clash between E-POWR-DEVC-F42 (assuming there was a layer of that name) and E-POWR-IDEN-F42, it will also show up as a clash in my report.

    Basically, anything in the first example, we point back to our other site and say "Fix it please." If it's something we clashed into with them (2nd example) or something where we clashed with ourselves (3rd example), I want to see that in the report because WE have to fix those..

    I think I may have figured it out with a wildcard in the first part.

    Category: Item
    Property: Layer
    Condition: Wildcard
    Value: *

    Negated

    Category: Item
    Property: Layer
    Condition: Contains
    Value: F42.

    Results look a lot moer like what I'm looking for..

    Thanks for the help.. It definitely got me thinking in the right direction.

    OK, an update to my last post.. It's still finding clashes that don't have the layer modifiers in either side of the clash.

    Now I have to get the backhoe out and start really digging deeper..

    Is there a way to set up your sets so that you avoid the negate condition?

    I know it's there, but my experience with it has been buggy at best.

    It would be great if that was a possibility...but there's no "Not Contains" option in find items. This is a perplexing one

    Looking at it a little deeper, I see some strange things happening. Look at the image below. The left side is right after I do a select all with the previously mentioned settings. That xx3P-1-1-261-FM-DM.DWG is the only file that was opened up like that.

    The one below it doesn't have a light blue border around the name, the one below that one does. So I opened each of those up and that shows the 2nd view.

    There is definitely some inconsistency in how it handles the selection tree once you set up that selection set..

    Basically, the 261 file that's opened in the left side of the picture, should have been represented just like the 400 drawing (the last one that's opened up). Both the 390 and 400 drawings have the light blue border around them. 390 shows all the layers in that drawing while 400 shows all but one.

    So why did it choose to open up the 261 drawing and not the rest of the drawings?

    Oh, it also opens up .nwc models all the way down through the layers and everything. That's a different story though..

    I think it's odd that it has this behavior but, I'm primarily interested in why I can't tell my Clash Detective to ignore any of the files in this set hitting other files in this set.
