I've thought some about that, but there are a few complications.

First of all, silhouette generation on a complex model can be a somewhat time consuming process so it needs to be able to be canceled. Things that are like that tend to be more technically difficult for me to incorporate into the saving mechanism rather than having it as a separate command. So it would take me additional development time to make that happen.

Also there are actually some other uses for silhouette generation such as generating parting lines for mold making.

Finally, I'm still just not completely sure yet about how the UI for a full hidden line generation should be structured. I have some idea that there probably needs to be a process where you generate a line drawing and get to see it and possibly edit it in a special 2D "printed page" type display rather than only having it baked directly in to AI export.
