Hi
got a confusion here
just wondering when to choose to create a new mesh in Edit mode rather than object mode?
under edit mode, new mesh created there will be linked to its corresponding
under object mode, the new mesh will be a new one?
is there any rule for choosing?
thank you
Generally, when they are two separate Objects, add the second one in Object Mode. For example. if you have a table and you want to add a plate, add a Circle, or an other Primitive, in Object Mode. When you have a tabletop, and want to add a leg, add a Circle or Cylinder or... to the tabletop in Edit Mode.
But don't stress about it; know that you can join two Objects, with CTRL+J (see the answer to your other question) and separate part of an Object (like the plate on the table), by, in Edit Mode press P > Seperate by Selection or by Loose Parts.
Sometimes you want to seperate the arms of a character for instance and do some changes to them and then combine (join) them again to the body.
There are no strict rules (and I still, after more than 10 years, make the wrong decision sometimes) but it is easy to 'fix'.
