I want to connect points and make a boundary

Grasshopper
1

I finally extract points from mesh objects. Now I want to connect points and make a boundary line(or polyline) with these points. A left image is my goal. When I checked the point order, it is not in sequence. I want to re-order the points in sequence. I am a beginner of grasshopper, please let me know what commands I need to use.

Looks like you do not require 6 and 7.

Yes, I donā€™t want point number 6, 7.

I finally re-order the point number by ā€˜sort along curveā€™ but canā€™t find out the way I can delete the point number 6, 7.

What about uploading the file with inernalised geometry?
That is always a good starter: ā€œHelp others to help you.ā€ :wink:
