Hi,
Following up from this:

How do I place structural member along its centroid line? Angles and PFCs are still placed incorrectly.
Best regards,

Hi Tuan,
From whatever we have seen, the place by centroid method works properly for beams of most section libraries across various Datasets.
Can you point out any particular section library where centroidal placement option is not working so that it can be rectified soon?

Hi Tathagata,
Can you tell me which default workspace and workset you used for your snapshot? I used the AU dataset and below is what I get:
Tathagata Saha said:works properly for beams of most section libraries across various Datasets
That is really intriguing, as I just did a quick test and I see completely opposite.
Test procedure: placing an unequal angle structural member by centroid placement option.
Dataset(s) seems to work properly: US
Dataset(s) doesn't work: AU, DE, NM, NZ
Dataset(s) that have center placement same as centroid placement (which is wrong): CN, DK, ES, FR, IT, SE, SG
UK dataset crashes for me and I haven't got time to do a clean install.
So from my test, there's only US dataset that is working properly, all other datasets either not working for centroid placement, or working wrongly.
Looking at your snapshot Tathagata, the placement point looks very much like middle,center, not true centroid.
The Centroid placement point is enabled only if the section is fully symmetric (wide flange I beam) or if the section properties includes a value for centroid.
Section properties are defined within xml files in the Data folder of the delivered datasets.
Example, if you are using UK dataset, the default location would be C:\ProgramData\Bentley\OpenBuildings CONNECT Edition\Configuration\Datasets\Dataset_UK\Data.
Centroid values (X, Y) can be added or modified for various section profiles by editing the xml files, using an xml editor or using the StructuralShapesTemplate.xls in the Data folder.
Once the centroid information is included, the placement by centroid method will place the structural members in the respective centroid defined for that profile.

Hope this helps.

Hi Raguram,
I first raised the issue back in SS6. Was told it's been fixed in CONNECT. See here:
https://communities.bentley.com/products/building/building_analysis___design/f/aecosim-speedikon-forum/161065/abd-ss6---centroid-information-for-member-placement
Then as you can see here, I was told it is working correctly in CONNECT.
Now you are telling me that I need to do some more work with the files delivered by Bentley to make it work correctly.
So which is it?
