What's wrong with this surface?

Dear community,

Something odd happened to the following surface I created. It was meant to be a closed strip, but seems to contain some holes in rendered view.

When creating a mesh, I also don’t see triangles in the zones where the strip is missing… Any ideas?

Many thanks in advance,

Kind regards,

Filip Rooms

Hi Filip - the trim curves are loopy… look closely at the bottom edge trims:


Thanks Pascal, didn’t zoom in this far.

This helped me to solve my problem :wink:
