1) Open a new document in Part Design
2) New sketch - a teardrop. This consists of
a) An arc of about 270 degrees centred at the origin
b) A line with a horizontal constraint
c) A line with a vertical constraint
d) Where one of the lines joins the end of the arc include a tangential constraint.
3) Pad the sketch.
4) On the new face draw a second identical sketch. Choose the curved part of the sketch as external geometry.
5) Pad the second sketch
At this point we should have a teardrop twice the height of the first, but the model falls apart. The results of the operation are inconsistent, but, put succinctly, the Teardrop Explodes.

Re: Failure to pad sketch drawn on a face which has the same shape
After opening the file in 0.17 dev the model is corrupted as explained in OP's post. Since this model was made in 0.16 it is possible to use Partdesign:Migrate function to upgrade the model to 0.17. Using this function fixes the model according to OP's expectations.Kunda1 wrote:What does this mean?cox wrote:Migrating the project file fixes the issue
