- In DSM-5 I created a surface
- sketched a profile line with 'Spline' along a 'Mirror line'
- 'Offset curve' to double it
- 'Fill' to close the edges
- The Surface shall be swept along a (similar shaped) profile that I sketched perpendicular (Z-Axis)
- Pull > Sweep > selecting the latter sketch line as sweep-profile (> blue)
- 'Full Pull' Button > the sweep-pull starts fine with an animation - see picture
- BUT it stops after ~1 second and the already created (green) body disappears again
