And that’s another thing for me to try to find out.
I know that TurboCad will save as .stl not sure about FreeCad yet. Haven’t got that far with it.
My instant dislike (probably irrational) of Fusion 360 is that it’s cloud based. At least with the previous two mentioned, I can use them when out on the boat and there’s no wifi. Also, I have ownership of any drawings I produce. I have a choice about sharing them freely, and, as some of my drawings are for commercially sensitive stuff, that’s important.
Clearly, as I’m going down the Marlin route (am I?) with a Rambo 1.4, I will need to check which programmes will speak the same lingo. (I think I’m on the right track here, please correct if wrong.)
