    Hi,

       drawing tubeplots does not alway work as expected:

       enter


 
s  := create3Space()$(ThreeSpace DFLOAT)

draw(curve(x,sin(x),0),x=0..4,style=="shade",tubeRadius==0.3,tubePoints==20,space==s)

draw(curve(x,sin(x),1),x=-4..4,style=="shade",tubeRadius==0.3,tubePoints==20,space==s)

   
     and after some scaling and rotating you get the appended  picture.

     
     -- Michael

Sorry for being slow: what exactly looks wrong to you -- is it the
discontinuity that shouldn't be there?
