I am super (SUPER) new to blender. I used it for a while in 2017 or 18, but only re-picked it up about a week ago. I've been trying to make an indention in a spherical (not perfectly circle,) object that is still the same shape as the spherical-like object. The intentions would be circles as well as U shapes. I have tried beveling a cylinder through it for the circle, but that makes the indention uneven, one side being much deeper than the other.
- make sure you have the looptools add-on enabled (comes with Blender, it is a free add-on)
1b) make sure your base geometry has quad faces so that the geometry still looks good if we add subdivision surface modifier
in edit mode: select one vertex where the center of your circular hole should be
press ctrl-b (bevel) then v (vertex bevel)
choose 2 segments
right click -> meshtools -> circle
select the vertices as in the gif and press J to connect them - by this you will guarantee a smooth surface later on
now press I to insert a support edge loop, move mouse only a little bit
- now press E to insert a support edge loop ....
- E -> move mouse now for depth
- E -> support loop
- I -> support loop
- add subdivision modifier
