The title says it all. I have followed the recommendations in without success.
In case it matters, the procedure that I followed is

1. Open the part. The sketch that I want to see in the drawing is showing.
2. Open a new drawing and place a back view
3. Place a section view looking down (i.e. in the direction of the sketch)

The section view is correct. Annotations are imported---even the dimensions of the sketch---but the sketch does not show on the drawing and I cannot make it show. The same problem occurs if I place a view rather than a section on the drawing.
I am using SW 2015-16 (SW 2015 SP 5.0). Any assistance is appreciated!
