How to close open volumes after a clipping transformation in Workbench 2022?

I used Workbench 2022 to clip buildings (composite surfaces) onto an area with the clipper transformer. The buildings at the clipper boundary however are open geometries (refer to screenshot). How can I insert closure surfaces to each boundary building to create closed volumes?

open building geometriesI tried to coerce the composite surfaces to a solid and coerce them back to surfaces after the clipping, but the method is not reliable, because most of the solids become faulty. Is there another solution?

 

Best regards

Alex

Hi @mralex007​,

Have you already given the SolidBuilder a try? That should create valid solids, and if you need to convert it back to a surface, I'd try the GeometryCoercer afterwards.

Hi @jovitaatsafe​,

thanks for the idea. However the SolidBuilder does not work in my case, because the buildings are stored in only a single aggregate feature. I didn't find a way to deaggregate the geometry grouped by each building, because the feature doesn't have any attributes stored...

@mralex007​ Did you solve this question? I am running into the same problem.

For anyone still looking for an answer :

 

I found that the GeometryValidator, with “Set of Issues to Detect” parameter set to “Surfaces And Solids” actually closed solids that had been clipped with the Clipper
