Issue:

When opening a drawing in ZWCAD, text may appear as “?” even without a missing font prompt. This usually happens when the required system font is missing. How can you add it?

Solution:

1. Open Text Style by clicking Format → Text Style (or type STYLE) and check the name of the missing font.

2. Obtain the font file from the Internet or other sources.

3. Locate the system Fonts folder, usually at C:\Windows\Fonts.

4. Copy the downloaded font into the Fonts folder; the system will automatically install it.
