I made a test file showing how one can approach this. The lines and surfaces are color coded. Each color is a separate sweep. In the end join all the surfaces.
Hey Gunter,
Steve Jobs was obsessed with G2 surfacing.
A method to make those pods is to use blend. Here is a video of doing it.
Just make your outer profile and extrude a surface
Then part it and use blend. Just after the blend, you can delete the extruded surface and just mirror the blend half result to get a very smooth pill to work on.
So like what Barry shows above, just stop at the extrude and blend that top part. (The surface needs to be open) Then just use only the blend result for 2 halves.
