It seems you don't save the file. we have sent an email to you how to recover them. If you do save, we are sure we can find it, because easyeda now has revision control, we backup every ctrl+s operation.

Vivi, Do mean that you have drawn some lines and added arrow heads to them but when you save and close the file and then open it again, the lines are still there but the arrow heads have gone?

Yes!!!The line still there but the arrows are disappear......and I really saved them!Do you know what's wrong with my it?thank you so much!!!@andyfierman

Vivi, You have found a bug. This is what happens: 1) Draw a `Line` with an `Arrow head` added (both from the Drawing Tools palette): ![enter image description here][1] 2) Then move the line or the arrow head and then move it back again so it is in the original position. 3) Then save the schematic, then reopen it and the arrow head is gone! ![enter image description here][2] [1]: /editor/20160123/56a365102917d.png [2]: /editor/20160123/56a365cf94a48.png

@support OK,let me see.Actually,I am sure I saved them.So I guess,maybe It's a bug or other problem......I'll try again by your way later.Thank you so much!!!

So,is it a bug that I cna't fix it?Can you tell me the other way to add the arrows on the line?Thank you so much!@andyfierman

Hi, I am sure this is bug, it is fixed, will upload soon. You would better not use arrow now.

OK!It's great.I'll try again tomorrow.Thanks a lot!!!@dillon
