The following 10 steps show how obtain a scallop sea-shell (or something similar to it!), perhaps I've a problem (credit for thi little tutorial goes to Wizard):

   1.  add axis
   2.  add lines (use front view) like this:


                      z
          __    ...   |       ...    __
      .__|  |__|      +---x      |__|  |__.


      -130         .... 0 ....              130


   3.  invoke the extrude req:
       to length 200
       scale x   0.5
       sections  10
   4.  add a primitive tube: radius 120
   5.  scale down the tube: 70% only y (shift-y)
   6.  adjust the tube position to cut the extruded shape like this:
           _________
          /         \
         /\         /\        top view
        /__\_______/__\


         |           |
      cutted      cutted


   7.  select extruded shape then tube and slice them
   8.  delete resulting objs except the 2 'planes'
       ('planes' should be part.2 and part.3):
                  _________
      part.2     /---------\


     and this          top view
                  _________
                 /         \
      part.3    /           \
                \_         _/
                  ---------


   9.  select first part.2 and then part.3, join them
   10. invoke mold req and conform to sphere:
       sphere radius 100
       object radius 320
After all these 10 steps, the resulting shape should be similar to a scallop sea-shell except for its too planar look: anyone has found the proper 'conform to sphere' (or what?) to show it much realistic?
