Help a newbie with BooleanUnion of three open polysurfaces

[Miranda_Lönnström]

Hi!

I´m sure this has been asked before, but I have three open polysurfaces, and I´m supposed to join them together. Two of them work just great, but there´s one of them that’s creating a bit of an issue, and I´m not sure how to resolve it

Could you please upload the cad data?

You can simply surface model it from curves, extrusions, and planar surfaces. Then you don’t have to fiddle with booleans, joining, etc.
