It failed for me too until I changed my units tolerance from 0.001 to 0.01.

You don’t need List Item.

cool, very appreciate. As a beginner, I never expect this problem connect with tolerance setting. By the way, if i want to apply some pattern(example picture) on this brep which have three surfaces. if the base surface is this kind of brep, what should i do, surface morph doesn’t work on brep.
