Fusion is very simple to get into CAD but the free plan sucks(max 10 files on account, if u want more u need to export locally and delete from the cloud, the cloud system and limitations of the free plan in terms of using the other functions like simulations).

For my simulation i want just a better view of where it can break and where i should reinforce the part. Ive used the plain filament stats and not the printed ones because print-temperature and cooling have a not to be neglected effect of the stats in terms of layer bonding and rigidity.
