Hi, new to 3D printing. My wife bought me a flash forge creator pro printer for our anniversary since I have been saying I'd like to get one for the past year or so. And well with that I'm looking to find a good 3D design software program to design some projects. I have been working some with tinker cad and it's ok, but I'm looking for something more. I downloaded the trial of Sketchup but the I couldn't even figure out how to lay a mm grid down or input dimensions for non associated shapes. And I searched the topics for a couple hours before giving up on it. I would like something like Fusion 360, but with maybe a one time cost.

I would also be interested in slicer recommendations as well. However from what I have read the Simplify 3D seems to be the top dog and I'm fairly certain that's probably the way I'll go.

But thanks for any help you can give me and I hope to not be to annoying as a newb to 3D printing.
