 I think the best opservation is tha with these 3D modelers we lrsn to
think differently.  We stop thinking about drawings that are on paper
and more about the product and it's 3D shape.    For example I want
to make a mount for asmall gear motor.  I make the exterior then Iuse
a CAD model of the motor as a "cutting tool" and place it where it goes
relative to the mount then tell fusion to "cut away" all the mout meterial
the in inside the motor's exterior surface. Then make bolt holes that
fit the motor's from mounting holes.   THis isnot drawing a part it is
making a model of the part.   Ideas like using an 3D part like a motor
of even a screwas acuting toolis forign tomost draftsmen

Invetor is AutoDesk's mature 3D modeler.  It has been around for a while is
is well used in indutry.   Itcompetes with Soild Works for beibg the
leader.     Fusion is the New Guy and I don't think is was based on Inventor
but many ideas much from it.  Fusion does both more and less then

Buy Inveter and Solid works come withvery hefty (four digit)  prices while
Fusion 360 is free for small-time users. and comes with built-in CAM that
can make g-code for mills and lathes and has very good integertion with
a couple slicers for printing.
