If you just need good modeling i and no drawing i would recommend FUSION 360 cost just 500€/Year and have all modeling tools from inventor
also T-splines! it has a nice version-controll.
Or Alibre Design. 2000€ and good drawing module, but no mesh-import.
its good for mechanical CAD and can import Rhino/Moi surfaces via Copy/Paste.
I Use Fusion for importing 3D-Scan and rebuild and change things with t-splines and classic CAD-tools.
I know Autodesk is EVIL but its the cheapest/most powerful app that i know.
@work i use Inventor so it workflow is similar to me.
Onshape is only online. what happens if you lost your connection?
Here in germany we have sometimes no internet.
because "Its all new to us..." ;-)
Inventor is good but expensive.. like solidworks and Solidedge and Creo
If you work every day with it and earn enough money... go with one of the big players
but if you need it just sometimes and not all of the toolset i would recommend
Alibe or Fusion.
Rhino is not Historybased/parametric and in mechanical CAD this is a nogo.
you allways have to change something and you dont want to rebuild it every time.
imagine you just have to change a fillet... in Rhino/moi you have to untrim the surfaces and trim them again and join them...
in a real CAD program you just klick on the Feature "fillet" and change the values to you need and then everything i rebuilding automaticly.
I real love moi and iam exited to buy the new update but i dont want to miss parametric / historybased CAD anymore.
sorry for my english.... :-)
