Contours in site model

[konst]

Hi 

I ve been trying to combine in one site model  the existing contours and the proposed contours with no success 

When I create a site model from the source data existing and proposed contours are not presented separataly in my final model

I must have been missing something ( or a lot as i am new to this )

Is there a way to do that or is it comlicated to explain on line

I ve attached a file containing both proposed and existing contours data

I would realy appreciate some help
