Good day.
I use Moi allot for 2d shapes...but here I am trying to fix this...I cannot seem to join these curves.
I have flatted it which is usually a problem...but trying to join them...can t see my mistake

Thanks!

Hi Matadem.
Everything is simple there. The same curves are superimposed on each other and they are one group.
Apply the "Separate" command to them and remove the excess.

Thank you!
it did the trick.

Question...shouldn't removeduplicates work also?....I can never seem to make it work :/

When several identical curves are "on top of each other", it is difficult for the program to determine how to connect the lines correctly, which is why this result is obtained.
Fonts often suffer from this disease. There was a cure for this somewhere on the forum.

Hi Matadem,

re:

RemoveDuplicates compares curves with other curves, it doesn't try to detect duplication in a single curve that backtracks over itself like you have here.

If you use Edit > Separate to break them apart then RemoveDuplicates can work here.
