How do I change the color of the yellow symbols so that they are more visible when printed?

The colors of symbols comply with the ISO standard.

Go to the HyDraw Options > Document Settings Tab > Miscellaneous section, and uncheck the box for “ISO 1219” under Symbol Color

If your drawing has a black background, the symbols will appear white on your screen, and it will print black when the drawing is printed.
