I am creating a wood plaque to be used with a CNC router with extrude cutting text on the surface. The text is in Old English font with the word "STRONGHOLD." However, when I try to extrude cut, the "L" is not selected and does not cut into the wood. With other fonts, this letter works fine but sometimes other letters do not cut. I have tried to select the letter after all the rest of of the letters automatically select but to no avail. Any suggestions about what I might do to fix this issue?
