Finding coplanar and concentric surfaces about cadquery

[bragostin]

Maybe comparing areas and centers with

center = face.val().Center().toTuple()
area = face.val().Area()

You could get a list of all surfaces with faces = cq_object.faces().vals() and then remove from this list the selected ones. That would leave you with a list of not selected surfaces.

Personally I use BoxSelector, like this

faces = cq_object.faces(cq.selectors.BoxSelector(corner0, corner1, boundingbox=True))

to select objects having the same, or contained in, bounding boxes.

Thank you, this is helpful! Do you have any idea how I could do the same for cylinders?

Thank you again, this works. But how can I select the remaining surfaces? "not" doesn't work. Basically I want to show all surfaces but color the selected ones.
