how to detect a clash for a duplicate element ?
I have some elements who are duplicate by wrong manipulation, I want to detect this with clash detection, clash detection detect collision but not the duplicata !
ps : other solution is a to use before "design file cleanup"
Can you please share a screenshot of the settings you have applied in clash detection?
Instead of setting the 'Criteria' to 'Levels' can you try once using 'References' and see if you still see no crashes?
it's the same result ... 0 clash
I had a look at it myself. It seems structural and architectural elements placed on top of another as duplicates shows clashes.
Please file a Service Request. We will have look at it more minutely and share with you the outcome, if required file a Defect based on the tests.
