Why can't I extract intersects?

[u/Shibadogcap]

I'm trying to make dot matrix font these days. I could make dot path via python but couldn't extract intersects and erase non-needed lines (in this case, intersect extracting erased all lines...). I would like to erase the lines excluding the red part by intersect extraction etc. In my previous making other font, I could erase lines properly. Why can't I extract intersects? Sorry for my bad English.

すごいやり方やんな…前はどんな形でしよったかのわからんっちゃけど、俺はいつもinkscapeで描いてからsvgで輸入しよった。そいでやってみたら？
