Hi @giovannipappalardiansys,

This looks to be due to the lateral defeaturing tolerance you are using for creating the base face. I see it is creating several more faces than I believe you are expecting due to the small tolerance it is picking up the variation in the curved edges between the upper and lower circular edges and creating very small sliver faces that fail to mesh successfully without cleanup.

I would suggest using a value in the region of 20% of your mesh size to avoid this for this case. Arbitrarily I used a value of 0.1 and this worked for me.

Hope this helps! Thanks
