Can you tell me which version of Valentina you are using?
The pattern file showed version 4.0 (this is the pattern file format version, not the same as the version of Valentina code.)
The uniontool saved your Grainline objects with commas instead of decimal places.
@dismine, what do you think about this?
Are you on a Mac? If so, have you made custom language &/or country selections in OSX preferences on your Mac?I ask this because the remainder of the data in your pattern file uses decimals, so it's interesting that it used commas for the grainlines after you used the detail join tool.
I replaced the commas in the two grainlines with decimals, and the pattern file opens properly.
When you open this file, it will show a message that it can't find the measurement file. Navigate to where your measurement file is on your computer.
I renamed your *.val file without parentheses & dashes & extra dots, just in case that was a problem, but it wasn't a problem. Rename this file back to your original filename if you wish.
