[help] Brep|plane section return open curve

Hello, I just start use GH for 2 weeks.

Today, I'm stuck up by open curve result from Brep|plane section. Only small portion of the Brep have this problem. Can someone tell my how this happened? and how can I solve this problem? I have attached the STEP file that I import into Rhino, the gh file and the 3dm file.

Thank you so much.

best regards from a noob.

Hi.

I'm not so sure but I suppose the bottom face of the surfboard seems to have been created from the wrong data.(Bad surface made from self intersecting curves or something)

Try to replace the bottom face of your brep with new one.

Thank you for reply. 고맙습니다

How did you get the bottom face fixed? did you replace it in the rhino without GH?
