I am working on a city asset. I have brought in lines from open street map for the roads, but I am not sure how to deal with intersections. I want something that looks like the video above. How to do?

thanks

Feek put his phone number on the video (SHOW MORE) Why don't you call him and ask him?

Try any of the following approaches in this hip file. Make sure you are using latest build as there are some bugs which have been fixed in recent builds (which would have cause a segfault). The example of the right is what I use

I do wish the node did handle this underneath the hood. I think that would be a valid RFE IMO

Hope this helps!

I only passed it on. It was pointed out to me by someone else.

Would be great to have a surefire method, I always end up randomly stabbing at nodes until it works.

That said, this time I had luck with a intersection stitch sop.
