Error message "Can't find point XY in list"


From this morning when I click on any point of my pattern I get this error message “Can’t find point XY in list”. Indeed the list is quite short but I’ve never deleted any construction point on this pattern. It seems the software cannot find the current points on the pattern. I use the basics blocks from Seamly 2D

Thank you for your help !



This normally happens when 2 arcs no longer meet to create a point because of the measurements changing. I can’t find C18a on the original pattern. Can you please direct message me with your pattern and measurement files so that I can see where it’s going wrong?

Thank you Grace,

Yes sure I can share. But the C18a point is just below the error message in my pattern.


What build version are you using? If it’s an older version it may have been fixed. If I’m correct, it’s an issue in the Property Editor, where it’s not finding the point to fill a combobox. If you’re using a current release, then there’s an issue I need to look at… for which it would be handy to have your pattern or to at least know what tool type c18a is.


Hello Douglas

I’m using this version


Ok. That’s a pretty current version. Can you provide you pattern (and any measurement file) so I can take a look?

BTW… if you click the image tool button, it will copy the system info to the clipboard and you can just paste it into a post here. For ex:
