I couldn’t stay in, I got out when Obama ruined the military. I have always been into designing stuff since the 1st grade, I never liked wood, but found my calling with metal. I have a side business now fabricating skid plates, it takes a long time to perfect each part. I was drawing to drafting and CAD in high school, but found cardboard design with solid mock up to test parts best.
I got super lucky with a full time AGR National Guard gig.
I call it CADAD, lol.
I will CAD a part, print it out on paper, and spray mount it to cardboard. Being able to have at least a cardboard piece allows you to see fitment and aesthetics three dimensionally. Then, if any changes are due, you can mark right on the cardboard. I seriously need to find a cardboard distributor that sells a cardboard stock with similar thickness to 16/18 gauge steel.
