Extract TIN from a DGN

I received a TOPO file from a surveyor and need to get a tin from it. This is my first time doing this and in previous drawings I notice this is done from points found by the surveyor. In my file I cannot find any points but there are contour lines.

My raw data including contour lines

After I build the tin and only showing created contour lines

Here are the triangles that were created.

I feel like there is something I am missing but I do not know what it is.
