To ease up the work of creating drawings I've editted the drafting standard to not show all hidden edges anymore. This created a problem which I'm struggling with to correct.
As you can see, lines are missing when there's an arc or circle drawn. This also happens in the other (front, sides, back etc.) views.
Edit the view style and make sure Silhouettes is toggled ON.
