Beam cut off contour seen on drawing

[Kvothe_23]

Hello,

when I cut off beam edge, the cutting contour is still seen on beam SP drawing.

What setting should I change, so the contour will not be seen? 

Greettings

What you see is called "HelperLine" so just select 'VisibleHidden' in presentation row instead of 'VisibleHidden HelperLine'
