I had an interesting email from All3DP today about using the 'Subdivision Surface Modifier' in Blender.
I loaded the Lola T163 file kindly sent to me today and tried smoothing the bodyshell...it's a RAM hungry process and if you try to push the process to far Blender crashes. After half a dozen attempts/crashes I managed to save a smoothed file.
I also had the same original file smoothed in much simpler fashion in 3D Builder...also a slow process but not crash-prone like Blender. I saved that file also.
Then I opened these two files with the original file in Qidi Print (Qidi's rehashed Cura to you and me) to compare the three:

From left to right: Original file, Blender smooth, 3D Builder smooth.
...I think 3D Builder did the best job.
