removing ScreenSpaceLines3D from viewport

description

if you remove a ScreenSpaceLines3D from the viewport, then the app crashes because the OnRender event is not removed, and the visual parent is missing then.
I fixed this for me locally (see attached file)
This is maybe not the best solution, but it works.

Hi, thanks for posting your source code. I've been searching everywhere, and it seems you are the only one who has done it. Thanks!
I pasted your code in mine, compiled the .dll and it works! I hope there are no memory leaks! I have read somewhere about memory leak problems associated to screenspacelines3d. Do you know something about that?

Hi, so far I did not notice any memory leaks. But the part of my program where I use the ScreenSpaceLines3D is used not verry often.

I have tested it yesterday and seems to work fine. I use this class quite often, because in my project the user should be able to design the geometry of a 3D object by changing the mess when feeling like. I'm happy I can finally get rid of those lines I don't want to display anymore in a "decent way". I hope no co-lateral problems will appear! :) Thanks again for your help!
