I’m trying to load car refs into blender, so I make 4 viewports front, back, ect. But when I load each of them in, they never match right. I know blueprints aren’t supposed to be perfect, but these are way off, what am I doing wrong?
If your blueprints are correct and accurate, then there is no problem.
Maybe you are thinking that the window areas of the “3D view” are different sizes. This is normal.
Give us a screenshot.
I’m not exactly sure what you mean, but here’s a screenshot.
It’s not the fact that it’s a bad reference, I have tried 2 different ones an each time they are way off like that.
And the first references I tried to bring in I had in anohter program and they were fine.
Any help is appreciated… 
If the original references are the same size as you say, then everything is good.
Try plotting some vertices. It looks like your windows are just zoomed at different strengths. It should still work.
I think I got it. I had to rotate my Top ref so it was facing downward, and then scale the refs the refs bigger.
