30 Day CAD Challenge


The 30 day modeling project was inspired by the work Rob Maldonado did in his One A Day project I heard about during the "Being an Engineer" Podcast. It was during the summer of 2021 where I was working as an intern at General Dynamics and completing my program at Google where I wanted to continue practicing my CAD skills and therefore took on the 30 day challenge. During this time I was modeling various items I was interested by, modeled complicated designs while learning from tutorials, and challenged myself to learn basics of surface modeling.

The focus below will be on some of my favorite models and what I learned from them.


Product Description

Multiple CAD models made with the focus on surface modeling, challenging tutorials, and each one had to be made and posted within the same day. The process would begin with brainstorming an idea for the day, finding a way to practice the modeling skill, and finally rendering the image utilizing different textures and appearances.
