Detect walls with modified profiles

[Anonymous]

I'm tasked with auditing a model we've received and a lot of the walls have modified profiles. I was wondering if it is possible to somehow select all the walls that have a modified profile and none of the regular 'rectangular walls?

I do have Ideate Explorer at my disposal, but could not find this particular parameter.

@ToanDNIf anything I think it is because we are using an older version of Dynamo at the office (2.0.3.0, core 1.3.4.6666).

I used Revit in English today, uninstalled all packages and reinstalled all the newest: same result.

The only thing I can think of that is not in order is the old Dynamo version.

My Dynamo version is the same as yours (2.0.3.0, core 1.3.4.6666) and it runs fine.

Can you share a screenshot of the warning popped up on the nodes after an execution? They will tell you what the errors are.

@ToanDNThe main problem is that I cannot ge the node to show up at all to even put it in a formula. When I search for SPRING, nothing comes up. If I understand correctly, I need the 'Springs.collector.ElementSketch', but I cannot obtain it.

Also, when I install Springs, it tells me that it is using a newer version of Dynamo, which is why I was thinking this was the problem.

i start with the idea of section profil of wall not elevation Profile (what you are looking for in presume).

it has to be by the RevitIFCDLL librairie.. i'll check and let you know.

[Yien_Chao]

ok let's resume.

i made a python to get ONLY walls modified manuallly.

The IFC.ExporterIFCUtils.HasElevationProfile() is the function to use.

basically, if you look a the image, only the last 2 will be output, the others modification are drive by another element.

is that what you are looking for?

@Yien_ChaoThat is exactly what I am looking for. I basically want to catch every time users made a sketch, because I consider it bad practice (bad for wall joining, level relationship, etc). This is for my model audit workflows.

OUT =  [i for i in elements if Autodesk.Revit.DB.IFC.ExporterIFCUtils.HasElevationProfile(i)]

Hi @Yien_Chao, this comes out as NULL on my end in the Watch window

Using Revit 2019.2 and Dynamo 1.3.4.666

[Yien_Chao]

can't say..i works fine here.

send your revit file?

[Yien_Chao]
