Iām not too sure how it works on Mac, but normally folders will be created in the program folder for multisize and individual measurements, so you need to navigate to the appropriate folder to save your pattern into it. Otherwise, you can open a folder in your User file and navigate to it.
Iām on Windows 10 and I have a Seamly folder on my desktop which, I have a Measurements & Patterns file inside it. Inside the Measurements file, I have my Individual & Multisize folders. This way, I have everything close at hand & donāt need to navigate to different places to find something.
Once youāve established where you would like to save everything, you can set the File > Application Preferences > File Paths in Seamly2D:
Then both Seamly2D & SeamlyME should find the folders without you needing to navigate to them every time.
