Some additional info for you:
I used MeshLab and and did a quadratic edge collapse decimation and was able to reduces the edges in the model by ~200,000. However Meshlab is not easy to use and looking at the model more it became apparent the basic tile model has some problems. There are a number of edges which IMO should not be there. There are some specific mathmatical relations required if you attempt to model it using the ARC tool and very small errors can cause the problems you see in that model.
If you want to correct ,create a cylinder( The OD I measured was 96.453 mm, make it just a zero thickness ( no wall thickness) I'll explain why below, extrude it up to the 250mm ht, select the top and scale down by the ratio to get the small dia you want ( I measuerd 71.190 mm for that). You can then go ahead and use the off set tool to set the 15mm thickness. The reason for waiting to this step is the scale tool will scale the thickness if you do it early. I then used the section tool to cut the truncated cylinder at one of the edges lines, make the section a group , intersect with model and delete the undesired portion. When I replaced this new tile with the ones in my posted model, which was based on what was in your orginial OP, the number of model edges reduced >= 200,000.
Just some thoughts for you ❓
Sorry, I was... delayed. :gandalf:
Thanks a lot, I clearly understood. I must change the way I work. I've used many industrial modelers for my job (Catia, Euclid, ... : oldies : ) and it's no good with softs like Sketchup or Blender.
Cheers. 😉
