I don't think you can draw a sine wave in Altium by any means. You can achieve a similar shape though, using Arcs (Place -> Arc). It depends how accurate do you need your sine wave to be and what is the purpose. You can also play around with round corner routing mode (start routing and hit Shift+Space a few times, to go through the different routing corner modes).
