Hi, I try to define in Bentley Geospatial Administrator feature for 3D buildings which are devided into walls and roof. I have already defined primary-feature 'building' as a polygon collection with several properties and I wonder how to define sub-features. I want walls and roof (two sub-features) to be polygons with different symbology which have properties definied in primary-feature. The placement method would be promote. So I could choose in Bentley Map some existing polygons and promote them to walls sub-feature and then choose polygons for roof sub-feature. So these chosen polygons represent one building with, for example, white walls and red roof. I added sub-features (polygon) for walls and roof in primary-feature 'building' (polygon collection), changed their symbology (PBS) and defined their 'max occurs' as unbounded and 'delete to parent' as lock. Then I tried to update placement method (with promote) but there was no placement method added for sub-feature...I have only placement for primary-feature in method and operations node... So maybe someone has already defined similar features and could help me? Tell me what I'm doing wrong and how should I define such features? Maybe is there any tutorial for defining sub-features? Regards, Ula
Hello,
There is no out of the box way to define placement methods on sub-features. However this can be done through customization. For your particular request here I would suggest looking at or using the Bentley Map CityGML compliant XFM schema. It has a custom promote placement command on the building allowing to create the walls, roofs, etc, exactly like what you are trying to do.

Note: for others we have also demonstrated and written a little procedure to load the citygml data in Oracle Spatial, view and edit the data in Bentley Map.
Thanks

Hi Francois,
after spending few days on this sub-features problem I've decided to give up...
I will do as in the Bentley Map CityGML compliant XFM schema, I will make separate features for buildings, walls and roofs and link them by parent_id.
But thank you for your answer!
