It seems i have a problem with this particular model.
In the drawing, there are two issues that occur:
1) The drawing doesn't show the complete model (some loft and boundary features are missing).
2) Some lines can't be hidden with the Hide/Show edges command.
The model is made in SW 2014.
You have mix of surfaces and solid in the model and the surface don't show up directly in the drawing vies. You need to use Model items to import/show surfaces in the model.
