SketchUp/OpenGL can't cope with very large distances, it's designed for nothing much bigger than groups of buildings [conversely very small sizes have issues too].
You will get inaccuracies, 'clipping planes' and all manner of problems otherwise.
I assume you are importing CAD data ?
The Import dialog's Options let you choose to ignore the CAD origin, and it will then place the imported geometry inside a component located at the SKP origin - not miles away.
If there is one common 'point' in the CAD and SKP you can then easily Move that component and snap it into place [then lock it].
Your issues might not be over...
If the CAD file contains blocks that become components when imported there is no issue if the blocks origin is placed near its geometry, but if the block's origin is at the CAD origin and the geometry miles away then similar clipping issues etc can still happen... to fix it explode these groups, or if you want to keep the separation select it and use the context-menu 'change-axes' to relocate the component's axes near its geometry - you can see components' axes if you set it under Model Info.
Another rarer glitch is with blocks imported into the CAD file, initially using the wrong units, that are then scaled down by say 1/1000 in the CAD file, rather than their geometry scaled down by that, so when they become SKP components they are actually in the database 1000x bigger that expected, so a CAD-house-block >> SKP-house-component that measures 10m in the model might actually be 10km inside its definition ! To fix that you can rescale the definition in the context-menu...
