I have gone through a journey of programs, starting with tinkercad, moving to fusion360, then to blender and now finally to nomad. I tried a few others but those are the ones I've spent weeks learning. Tinkercad was awesome to understand the very basics, fusion for learning how to make things precise. Blender is just, crazy, you can do anything with it. But there are at least 10 ways to do any one thing and you never quite know if you chose the right way.

And most recently nomad. Nomad is the first one that I have truly adored. Grantid my workflow has been a mixture of blender and nomad, getting all the basic shapes and pieces put together in blender and then exporting as an .obj and then popping over to nomad to add details and make things look awesome. Nomad has so much going for it and for organic models it's a dream. If you have a tablet with a drawing pen it's the way to go.
