Is there any systematically method to assign classification for ALL objects ?

[marcoho01]

Hello,

I would like to know if there is any method to select a classification system and assign classifications to all objects in a systematic way?

I have tried exporting a schedule (as an Excel file) and assigning classifications to all objects, then importing it using the "Import Property Values into Elements" option under "Interoperability". However, this method did not change the classifications of those objects.

Thank you!

Operating system used: Windows 10

I understand your point. The objects without classifications have been colored red, but how can I hide the other objects that already have classifications?

You do not necessarily have to assign each individual element to a classification. You can also use “merge items” to reclassify more elements at once.

True.

Just don't include any fields such as 'Element ID', otherwise the items may become unique and won't merge.

That is why I like Find & Select.

You select all that you want and then 'Show selection in 3D'

But there is really no need if you find and select all walls with no classification.

Once they are selected, just add the classification in the wall settings.

Then find & select all railings with no classification and add classification.

Then all stairs.

I guess that is where Xandros is saying schedules are more powerful.

You can schedule all 3D elements that have no classification.

Then in the fields just add element type and classification.

Tick the 'Merge Items' box and you should have one item for stirs, one for railings, one for walls, etc.

Then just change the classification right there in the schedule and all of that element type will change.

So now I do agree with @Xandros that schedules can be more powerful.

This is why I like schedules:

I can add, remove, refine the criteria (you can do that with find/select, but need to resave your saved search, schedule just stays the way you last refined it), add other data to the schedule (layers, home story etc.) to help understand what I am seeing, I can play with switching between merging if uniform values only, or any value. I am not tied to what I see in a model or plan, I am working on the complete project. If I need to see the items, I can always ask the schedule to show on plan or 3D.

Ultimately it is good to have schedules to check the quality of your model: do I have unclassified elements? do I have elements in a classification system I don't wish to use etc. The schedule is there in you view map, you just need to load it. As with find and select you don't have a ready-made report.

And one more thing: sometimes find and select doesn't find the items a schedule does! For instance members of railings, curtain walls and stairs have their own classifications, and these don't get found with find and select, because that focuses on the classification of the entire railing or stair. But these are listed in a schedule. They are a pain to identify and fix though...
