Hi all,

I seem to be having problems importing 3D contour data from a land survey into revit to create my site.  I am new to this and have successfully completed the tutorials which work fine - which makes me think there is something i'm doing worng with my specific cad file. 

I've checked the points all have valid z coordinates (so the drawing isnt flat), I import with only the relevant layers (I've actually frozen the not needed data on the cad file now) when I create toposurface I've tried creating from both the contours layer and the survey points layer from the cad file - it seems to create contours but all in black lines, yet when I try to view in 3D I get nothing (blank screen). 

On occaissons I've been greeted with a vertical pink line that changes in dimension as I orbit around it.  I've checked my cameras to make sure i'm not being really stupid - although I wouldnt rule anything out at this stage!

I've included the cad file with the frozen layers - if anyone can help it would be greatly appreciated!

Many thanksKev
