small cross charm

I made this thing for an engineering project. It took me like 2 weeks but that is because I am new to using inventor. It is of a gothic style and can be resized to fit on a necklace or chain. My teacher says I have to tell you all what I learned when making this. Most of what i learned had to do with the sketching, at first when I was starting this project I did not know i had to make different sketches for different features, so i didn't know I had to make a separate sketch for embossing, and that the sketch for embossing my lines had to be closed. And then I learned that you cant chamfer small features very well, so you have to adjust the size of your chamfer. I also leaned how to use the mirror tool and how to create a very symmetric design, while also keeping it interesting visually despite how symmetric it is. Making this should be easy for any experienced engineer or 3d model maker.

But for those of you who do not know exactly how to get started on making one of your own design
