Suddenly, some lines are light-gray instead of black: ![image](https://global.discourse-cdn.com/sketchup/original/3X/7/e/7edb830f8214ad804dae5e5b23b3dfac04471f47.png) all black in SU: ![image](https://global.discourse-cdn.com/sketchup/original/3X/c/0/c07bb63b596d89ab0e7d989f9dceda489f71a071.png) Seems like it’s not a style thing, as only the main building has gray lines, the stuff at the top is showing correct. So i suspect it’s a property of the geometry, material or color that i accidentally added to a group? But i can’t figure out what it is… Any ideas? EDIT: At around the same time i started to notice something in SU, that i now realize is related, but i don’t see how: > [@What is this diagonal grid on the faces of my active group?](https://forums.sketchup.com/t/what-is-this-diagonal-grid-on-the-faces-of-my-active-group/110206/2): > > What version of SketchUp?

Like I said in the other thread, share the file. Upload the LayOut file so we can see what you’ve got set up. ---

This is what I see when I open your LO file… ![Screenshot%20-%2012_3_2019%20%2C%208_28_44%20AM](https://global.discourse-cdn.com/sketchup/original/3X/5/3/53ad6d1d9ba7928d3ca6477dffecb259adc496a5.png) The content on the VP exist /kept HATCH layer masks some edges when that layer is turned on. I also notice you’ve modified the scene called P EG 2D New in LO which is not a good thing to do. ---

Thanks all. The Solution was to change back to default material in the model, see the other thread. As the linework looked good in SU, i think it’s kind of an edge case bug, that LO did render these viewports differently. > [@DaveR](#): > > also notice you’ve modified the scene called P EG 2D New in LO which is not a good thing to do. Thanks, i know (in theory). But i was not aware of that change, reverted it. It happens all the time to me, that viewport settings change without me noticing. No idea what i do there. But they seem to be subtle changes, which are not visible on the page. ---

You might consider locking the viewports or at least lock the layer they are on to prevent making changes to them that result in modified scenes. ---
