Clash detection: How to pick linked model elements by ID?

[indiana_j0nes]

Okay the answer i found through forum post searches is NO!

But i am interested how do your normally go about it.

I ran a class detection between our architectural Model and the MEP Model and Revit returned me with the list of collisions showing ID of elements in conflict from both.

My present work around is I 3D isolate the element in conflict within the architectural Model and then investigate which MEP elements from the linked MEP model are the ones having the collision.

Is there a better workaround to pick the linked model elements by its ID?

Thankyou all for sharing your ideas.

Cheers

Found these: there is a api syntax for it, but does anyone know of a plugin or so?

And here is a dynamo which seems to do what I am looking for:

You can export the results from the Interference check to Excel, where you can isolate the element IDs.  These can then be pasted back into select by ID.

Or use Navisworks to do this - much easier to isolate the elements.

Hi Tim,

Thankyou for your reply, Oh well maybe i didnt frame my question properly.

I have the model element IDs from the linked model, but my issue is that I cant highlight them in my model.

When I do pick by ID and give the ID's it tells me cant find the ID/element in this project. (ofcourse it resides in the linked model), How can I query what the element ID is for elements from a linked model. (I know its not possible, I would like to know your workaround for this).

Hope i was able to put across my question well this time.

Cheers,

K

I assume that you would like to send a list of clashing elements to the author of the MEP model so that the clashes can be corrected.  Can you not do your check the other way round?  Open the MEP model and link the Arch model and check for the interferences.  The the element IDs can be obtained.

Allow me to elaborate.

We work in house in two teams, the MEP have a face-based dummy wall opening family which they host on to our linked model.

We then link their model and place these wall opening that are actually cutting through the wall in our model.

(I know a efficient way could have been a copy-monitored workflow).

So far so good. The issue arises when we have to displace some openings and then the MEP guys need to be notified they need to reroute their piping/cable-trays/etc. Now from the report Revit produces we can very well find-out which area or wall instance do their issues dwell on. But there are more than one Piping or Cable trays or other MEP objects running through that wall, some are critical some aren't, we arent allowed to work on each others models. So a ID query workaround for linked model is what we need to point out the exact MEP objects, rather than guess working based on the report description and comparing it with the properties of the MEP objects revit shows upon selection.

Hope this was clearly put. Thank you for your time and ideas.

Is this about not being able to easily differentiate the elements in the view?  Why not create a selection set filter from a group of element IDs and change their color to make them more prominent in the view?  Or am I completely missing your point?  If so; nevermind.

Oh well, I wanted a way to pick an element from a linked model and know its id.

Revit shows me the id of the elements from the linked model causing the collision, but I would like to investigate it further before sending out the report or the ids to the MEP team.

Thanks for your tips.
