Hey All

I have been making a certain part for a couple years by hand and wanted to up my production. SO I bought a new patriot a few months ago, in order to help with production. I am very new to cnc machining although I have been doing a lot of reading here and there. I have also taken a while to get familiar with the machine.

The product will be made of a composite acrylic material and will need a slightly complicated program to produce it..I assume. The part is small, curved and has an o-ring.

Is there a cad program someone can reccoment that is free or inexpensive that will allow me to draw this part out in order to convert it to g-code. I have a copy of autocad, but it seems pretty complex for what I want to do.

Any reccomended starting point would be appreciated
