Hi! I created instances within the file and the preview of my Regular weight disappeared. And the preview of the instances as well. I have the 3.2.3 (3260) version of Glyphs and the Version 14.6.1 (23G93) of Sonoma. Thank you in advance for your help!
Can you post a screenshot of Font Info > Masters?
Any reason you set the ascender and descender to zero?
Those are used for several things, including line spacing and calculating the size of the drawing in Font View. Usually ascender + descender should be similar to the units per em as set in the Font Info > Fonts.
My teacher looked at the font info and said that it’s okay because it’s a unicase and monospace font.
Those two values are a technical requirement. Has nothing to do with the design of your font. Just use the same value as the cap height. Have a look at this page: Vertical metrics | Glyphs
There is no ascender or descender in my design. That’s the reason why we set it to zero. The link you attached didn’t explained why there is no preview in my file unfortunately…
But instances are working and if I click on the letters there are the instances inside.
I’ve set the ascender and descender to a random number and there is still no preview only when clicking into the letter.
Again. That is not at all relevant.
Use -50 for the descender. I add an error message to prevent invalid values.
