Q: How do I use the font files? 
A: first, download the zip file and extract it so you have access to the .ttf file. Right click the ttf file itself and “install” it. Once installed, go into your CAD program and  click the text tool. The dropdown should display a list of fonts installed on your computer, so from that list, scroll until you see a font starting with “CNC…” and select it. Start typing and that font should type out normal with bridges
