WHAT TO LOOK FOR IN  CAD DATA  FILES

Feel free to play with the drawings, it sounds a bit light hearted but by zooming in and panning you can

Look at the quality of the linework, look for lines joining in a proper L or T shape.  
Look at the construction of the features, are pillars and columns square to the wall line?
Look at the Street Furniture, is it drawn to scale? or do you get a X symbol?
Zoom in close, many files look OK when plotted but beware, unless features are constructed properly you may get inconsistent results when using the data.

By playing with the layers you can see how well the layering is implemented,

You should not loose any walls when you turn the doors off for example.
Turn ON single layers in turn, look for obvious gaps
Can you turn off all the text to produce plans a different sizes?
