CRACKED IT.

 It's been an eventful night. I couldn't sleep for pondering on the awful mesh render I posted yesterday. Eventually I thought to look at export settings in FreeCAD Preferences, nothing there of any relevance. I went to bed, not for long, I had no sooner dropped off to sleep than there was one hell off a commotion. Alf had his dew claw caught in the keyring thingy on his collar. He's a real wuss and was growling and whimpering, Moll was barking in sympathy, bloody chaos it was. Sorted him out without amputating his leg and all was well again.

 I couldn't get back to sleep so got up, gave in and started looking at FreeCAD forums. The settings I needed are in Preferences, Import/Export but to get the one I wanted I had to be in the Mesh Workbench. Silly me. Dropping Angular Deflection from something silly o'clock to 2 and Deviation to 0.01 and the job looked better. 

This is yesterday's effort.

Today's.

Not perfect. It's good enough I think. These were imported into Blender as an OBJ. file, they would probably be better as an STP. file but unless I can find an Add-On for Blender it won't accept them. 

Frustrating though producing computer generated images can be, it is a never ending voyage of discovery.

I am half inclined to model and assemble a cutaway blower, I'll try and animate it in FreeCAD, If I have any success I'll make a little video of it......Don't hold your breath, I suspect it may be very advanced CAD. First a siesta is in order.
