I have some text for a plaque that I engraved for my mothers memorial. I need to make some changes but I can't remember what font style and text size I used when I did the cad side a while ago. The text is vectorized. I am using V21. Can anyone tell me how to make BobCad tell me what font and size the existing text is so that I can change a date in the midst of a line?

I'm not sure but I think once the text has been converted to vector there is no way of knowing. You could try typing a couple of the same letters or number and then match the font by changing it or if you have all the letters or/and numbers needed for the correct date you could copy and paste to create the correction... hope this helps
