How can you remove a damaged nor stuck shower drain

Do you mean the actual drain line or the drain part that goes through the bottom of the shower>??

How can I remove both the drain in the shower and the drain line. The drain itself is stuck and a little damaged from trying to get it out, I might have to go through the ceiling to get to it and probably will have to romove some part of the drain line too. Could you give me directions on this please, thank you.:o

We had a discussion recently about removing a bathtub shoe. Assuming it's similar yoy will have to create access and cut it off. Recommendations were primarily to use a saws all although I did it with a surface grinder with metal cutting blade because that's what I had access too.
