The section box cannot cut some generic model

I made some model of seam roof panel by dynamo and cut it by the void mass. But some of the families(each seam is a individual file) linger in the view despite has been cut by a section box. Did I mistake something, or is it an error?

@cloud2924 , hi

Did you check, whether your families are able to cut ? Where is here the Dynamo issue… :slight_smile:
