It's easy enough when you get used it but there are some things I didn't see straight away - like how much space each element takes up in your model so make sure this fits if its going to take too long/much time (it was taking quite sometime due to all elements being displayed).
There isn’t anything bad about using FLoCA at first though maybe just look around different programs before deciding which one would suit best! You're solving problems relating to design engineering projects within minutes without having any prior experience whatsoever.
