I am attempting to model this dining room table. I am having a difficult time trying to create a polyline of the top profile. I've tried using lines, arcs and splines but cannot get an accurate representation of the profile. I can select the table top outline but cannot turn the marching ants into a polyline either. Please someone tell me the trick to making an outline of this table top so I can build the top and do a 3D molded polyline for the sides of the top. I'll deal with the legs once I get this much done. Thank you in advance for any help you can provide.
