Deformed grid for daylight study



Hi Guys I need help!
Do any of you know why the grid’s square is deformed? I’ve tried everything but nothing has worked…

I think the Problem is because the model is not paralel to the view. Should I rotate it? Is there not another option?

Now I have rotated the geometry and the problem with this way… But now I realised that there is a little issue with the position of the grid. Do anybody knows what this is?

Manyyyy thanks
