Let say you have a hand drawn site contour plan that you want to model. You can try putting hundreds of little points along the lines and you may get what you want but probably not. So heres the way I do it.
1. create a level for each major contour elevation(ie. every 10')
2. create a site plan in which you can see all these levels from the top.
3. using model lines(splines) trace your image setting the work plane to the appropriate level.
4. continue step 3 until you have a 3d contour map of lines at the appropriate levels
5. export the 3d view to dwg.
6. Import the dwg origin to origin in the site plan view
7. create topo surf using imported dwg.
There you go.
