Import a surveyor dwg: terrain layers come in as blocks

[MonolithicDome]

I have been trying to import a dwg from a surveyor, but the topo lines are coming in as blocks.  I did select to convert to polyline at the beginning of the import wizard.

 

Can anyone offer any suggestions on what I may be doing wrong? 

 

Thank you Kindly,
