Create Surface from 3D data

I am working in Civils 3D 2014 and I have a survey with points already on the correct elevation layer, I have tried creating a surface from this but it does not show up.

My process:

I create a new drawing and insert a block (my topo survey) and click explode when I do this

- I create the surface by TIN and make sure I have the correct layer for the points that I am selecting

- Click ok

- Then go into that surface and turn on all layers and refresh - still nothing

- I also made sure that my surface style was 1m contours so I would definately see this 


Any ideas?  I am very new to all this!

Do you have a TXT or CSV file of the points? If so you can import them as Cogo Points or attach the file to your Surface.


If not you'll have to create the Surface from Drawing Objects and select the point blocks.

Or you can throw your hands in the air scream at the computer, quit your job and relocate to Sri Lanka. Although the previous statement sounds a little less problematic. Have a great Halloween!
