Blocky and Wavy Lines in Revit Model

[james.melvillEHTCX]

Hi, I'm struggling with very poor views in Revit due to blocky and wavy lines defining all my structures. These are mostly familiys that I made and have placed into my Revit Model. But I can't detail them as what you see is not where you click. You can see in the images what I'm talking about. in the one image I have selected the one item and you can see the true lines, but then the one next to is is all crazy.  

How can I fix this?

How large is the model, are these items far from the internal origin?

@RPTHOMAS108 ,

The Model is not too bug. About 26MB. But It is far from the origion. I had a look at re-setting the origion to be closer to the coordinates where I nee dto work and this sees to be making a big differecne.  Thanks for the reply and for confgirming my hunch.
