When a word is underlined it is too close to the word and if there is an "E" or "F" you cannot tell which letter it is. How can I fix this?
I remember this from a while back but haven't seen it lately. Do you have a thickness assigned to your text? Are you using something besides FONT or FILLED (Creo default fonts)?
This is the most annoying thing - Creo should have a variable offset from the baseline for underlines, but they don't yet. I think if it is important, skip the font-based underline and just create a line. More hassle, but more legible.
I found with the default font you can reduce the thickness value, which makes the text and the underline thinner, but the text would possibly be too thin for your requirements.
Using a True Type font such as Arial means you can change the Thickness and this only changes the underline thickness.
This may be an option, otherwise it means sketching lines under the text.
