A Free Program I Can Use For Patent Drawings? |

Hi all, I'm an aspiring inventor submitting my first patent. I've reached the exciting stage where I need to create drawings and I want to use a CAD program. The problem is two-fold: 1) I don't have any money to invest in a CAD program 2) There are so many free options available I don't know what's the easiest/best option specifically for patent type (mostly isometric) submissions to the USPTO. Any assistance or guidance would be greatly appreciated... thanks! -Alex |

Blender is the best free one. It has more technical capability than other free programs, thus it is less intuitive to use. Lots of tutorials online and YouTube. |

I highly recommend Autodesk Fusion 360 - *free* as long as you are a "startup" or "hobbyist" (meaning you are using it just for fun or making less than $100,000 with it). Fusion 360 includes parametric 3D modeling, rendering, drawings (incl. isometric), CAM and even engineering analysis: |
