As you can see in the pic below i have some points "Sông Vĩnh Trà". Their Geometry type are Multipoints. They are parts of a river, so i want to connect them to display the river on the map. I tried to search for "connecting Multipoint arcgis" but i still can't find solution.
As there are only 6 points, I'd suggest you just create a new line feature-class and draw the line connecting the 6 points.
Multipoints won't display as lines. If they are created in some kind of identifiable order, it could be scripted to draw the line from vertex to vertex (or point to point), however for so few points it's not likely to be worth the effort.
Assisted by comments from @Midavalo, I now know that multipoints won't display as lines so i will create a new line feature class and draw a line to connect them.
