Should I use Subd
Or using boolean
IMO , if you can, model it normally then bevel the abrupt edges. Weird geometries can be finicky, but maybe worth a try.
And welcome to the BlenderArtists community.
Thank you
I have been trying many methods
But i don’t know if i am doing correct
I tried subd with boolean to get the erupted edges but i don’t liked
It looks good except for the triangulated faces. If you can make a clean quad patch to go over it using retopo, and weld it to the surrounding loop it will look a lot better. If there are any tiny triangles around the edge where the patch will need to fit, merge them ( M key in edit mode )
Also, vertex slide can be handy for orienting vertices before merging. If you could throw up a wireframe, I might be able to give you a better solution.
