How to intersect edges

[upstream]

Hello,
In the attached how can I interest the edges so that there is vertex at intersections as marked? I tried Tinycad addon >intersect selected edges but it didint work

That feature is available.
Auto Merge must be enabled for use.

yes it is enabled but still doesnt work. can you see attached file?
test edge intersect.blend (524.9 KB)

The object appears to have an unknown error.

1. Initialize scale in object mode
2. Cross-point cutting with Tinycad in Edit mode.
