I’ve been using Shapr3D for the past several months on a project and just noticed some lines I’ve never seen before in my model. Some seem to be random lines and some seems to be related a part of a model. All of these black lines are not clickable.  
This is something I just noticed in the last few hours of using Shapr prior to writing this (Dec. 8th, 1:58 PST). Is this a known issue or a bug? Thanks

Hi,

Could you share a screenshot, or the model itself? The app version, and the device used with OS version could also help us. Thanks!

Hi Laci. Thanks for the quick response.  
I just restarted my system and now the black lines are gone.  
Sorry, I should have tried that before posting. 😛
