Rhino files getting unusually large and generate weird objects

[LI_YISI]

Hi I am new to Rhino and I am working on a very simple project. But when I export the files to Cura, it generates some really weird objects. What’s wrong with that? Can someone help?

Thank you!

Please turn off the Thickness option to all objects, then try to export it again,
