I am detailing a drawing of which has radii tangent to two surfaces.  Beyond these radii are tangent line segments that I cannot turn off.  I have tried several different things, including RMB---> tangent edges---> tangent edges removed.  This just removes the tangent lines from the model, where these radii meet the straight surface(s).

I have also tried Tools---> Options--->Display--->Part/Assembly tangent edge display---->REMOVED.  Yet, this doesn't get rid of them.

Again, I am not trying to remove the tangent lines on the model but rather on the drawing/detail.  It is a wire that I am detailing but have removed the outer profile of the wire and am showing only the centerline (as a solid line) in the detail.  Basically, I am creating a template on which the profile will be engraved and I want to detail this profile.

Thanks, in advance, for your help!
