Inconsistant importing of .eps circles in font!!

I hope someone can solve this infuriating problem!! I am a fetus in the world of Font making but sometimes I can make dot fonts for the Rhinestone industry and sometimes when importing the .eps (either from Corel or AI) the circles are retained and sometimes they are not! Even a more perplexing problem is that from the same .eps file that contains all the letters of the alphabet from which then I export into separate .eps files (using the exact same export settings), some of them import beautifully and some don’t!!!
I have read and tweaked and experimented with different settings to no avail.
With some characters I get this unwanted result

when I want this result

Actually, when I combined a mixture of files that imported properly with those that didn’t, none of them will import correctly. An example is the “ad” file attached.

I have attached some files for you to try please. :confused:

This has been driving me absolutely nuts now for weeks!

I can confirm the issue, but don’t see any obvious reason.

Have you tried using PDF instead of EPS ?

Yes, I have tried EVERY format. I am using FC 6.5. I thought perhaps it may be a Corel problem when exporting but it happens with AI as well. One time I imported it and it didn’t import properly but later I tried again with the same file - it imported perfectly??? If it wasn’t for the inconsistency I would presume it was a setting in FC.
Anything you may think I could try?

Try exporting at a larger size, then shrink the glyphs down after importing.

Do you mean in .EPS making it larger or .PDF?

Either, but making it ten times bigger in DrawPlus, then exporting as PDF doesn’t make any difference.

During the import the circles are converted from cubic to quadratic Bezier curves. To have a 100% exact match after the conversion you will need endless points, which is uhhh pointless :wink:

So somehow the quality depends on the dimension of the circle. Large circles will require more detail, thus more points, while small circles can do with less points.

I tried scaling the .EPS up threefold and I still don’t get the round circles. I understand there is a conversion from cubic to quadratic Bezier curves but what I do not understand is the inconsistent conversion.
The font is made up of circles 3.30mm in diameter. Every circle in every character is the same so why are some importing correctly and others not? Is there a way that I can select them as a group and add more nodes?

The solution is to increase the default units per em from 2048 to 4096 or 8192.

  1. In the font’s glyph overview, select all and copy.
  2. From the Format, Settings Dialogue, Header tab, open the “Units per em” dropdown and increase the value to 4096 (or 8192). OK
  3. The size of any existing glyphs will have been reduced in proportion, so paste the clipboard contents to return them to their designed size.

If starting a new font from scratch without any default outlines, this copy/paste step is not needed.

Now, your small circles will import with more nodes.

FontCreator is inconsistent, but not always. :wink:

Oh my God!!! You solved it!!! :smiley: :smiley: :smiley: :smiley: :smiley:
Thank you sooo much!! You don’t know how long I have tried to solve this problem but I instinctively knew that it was a matter of changing some sort of setting!
I bow to your greatness Master :wink:
Thank you for sharing your time and knowledge with all of us.
