A very simple yet extremely convenient feature that’s been a part of OS for sometime now has been the “Drop” tool.
When adding modifiers or separating parts into objects they may not be flat or placed on the correct face surface. This is most annoying when adding a modifier to a model for example, the first 5mm of a benchy being 100% infill. Well you’ll notice if you add a shape it’ll be floating but you’ll be able to “center” the objects.
The “Drop” feature will drop selected object to the build plate [Z0] boom done.
Hope to see this be implemented sooner than later.
