Orient Objects

Hi! I’m working on a model that I’m gonna take to laser cut. Can somebody help me out and tell me how can I align the pieces to the ¨ground¨ level, as shown in the picture? So I can send them to Autocad. Thanks in advance!

Hi Juana - do you have the curves that generated these objects? I am not sure what the goal is for laser cutting in this case - do you need to get round pipes when done?
