As a other Fusion users have experienced, I have also often met the Fusion performance bottleneck, and the video by Wintergatan https://www.youtube.com/watch?v=9zL8pRDxPck really sums this up. Also having complex drawings or medium sized pattern constructions can bring Fusion to its knees.
I wonder why Fusion being fairly has been made with such limitations from the beginning, when Autodesk having such a long (if not the longest) experience in building CAD programs.
Idea: Improve the Fusion engine so it can handle large / complex assemblies / constructions. If not, add a clear warning label to Fusion, that it cannot be used for medium sized and big assemblies constructions (in terms of complexity - number of bodies / components) and you should invest in (learning) Inventor, Solidworks or Pro Engineer instead.
Fusion is great - really great - but it is not great to have spend thousands of hours on mastering it to learn, it cannot handle large projects, when you get to that and you have to migrate and learn something new, when you are getting serious and busy.
What do you think?
