Line art fail

I’ve been trying to get only the lines and based on a tutorial I watched I excluded all the layers, checked transparency, and made sure to check line art in that window. But every picture I save is pure black like I made it in paint and just clicked the bucket took instead of a 3d cad program.

This section of the forum is reserved for tutorials, not posting question threads.

Regarding your question,
your post also doesn’t make much sense, you haven’t linked the tutorial you watched and neither did you post your blend file. Please post as much information as possible when asking questions.

Sorry about that.
