I also payed attention to the rule of thumb of having said Tolerance be 1\/10 of the intended minimum (tile?) size.<\/p>\n<p>But none of that makes much sense to me without understanding what Max Size does. I understand that it makes for a finer tiling too, and that either one can be used, but I&#8217;d rather know the different ways in which they let the user achieve said results.<\/p>\n<p>In the tutorial, faceting refinement was obtained modifying just the tolerance first, switching it from 0 (off) to 0.01. Then, similar results were achieved leaving the Tolerance off but lowering the Max Size.<br \/>Again, this clearly showed that both can be used, but with hardly any idea about what&#8217;s the governing logic behind it.<br \/>It looks almost as if they were redundant upper bound size values, since the coarsest Tolerance 0 still lets you lower the Max Size indefinitely and vice versa&#8230;<\/p>\n<p>So yeah, I&#8217;d love to learn more about it!!<\/p>\n","protected":false},"template":"","class_list":["post-357724","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["60427","62"],"_bbp_author_ip":["23.206.193.154"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["867"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["357724"],"_bbp_forum_id":["27790"],"_bbp_engagement":["62","60427"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["357806"],"_bbp_last_active_id":["357806"],"_bbp_last_active_time":["2024-03-19 06:02:48"]},"test":"alex-chiellamail-polimi-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/357724","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/357724\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=357724"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
