Open up your site plan view then file import your topo dwg file, check the current view only. On the site design tab click toposurface then click use imported>>Import Instance then pick your imported dwg on screen then on the pop up dialog box you can just click ok then lastly click finish surface.
Hope this helps....

Make certian that the drawing you received from the surveyor has the Z coordinates for the contours. Not always included. You can go into the drawing and maually set them, if necessary.
Also, often the civil or surveyor's drawing will be in decimal units and your drawing will be in architectural units. I usually will take the surveyor's drawing and save it as a different name. Then I will change the units from decimal to architectural and then scale the drawing a 12 times for the unit conversion.
Import as razorback describes and then majic happens.
I still haven't gotten the 'Relocate Project' trick as yet. When you import topo, it will come in at actual grade levels while your project is usually set at 0' elevation. Relocating the project relocates the topo also, so you keep chasing the grades.

it is help a little, but my topo does not look right...
The highest point RL 50.00 should happen at the left hand side, and the lowest point is right hand side. the result is totally wrong.

Did you forget to attach the .dwg file? Notice there is a 2Mb limit on the file size.

why8888,
Try saving the file as a different name, delete all the extraneous layers except the contour data, purge the file then saveas again with the same file name. If necessary, zip the file and see if this reduces the file size. Saveas again removes all the historical data since the renaming.

why8888,
Your dwg file worked okay for me. The file you attached had no values for any of the Z coordinates, so I merely added the value you had as contour notes. I then copied the contours without text onto a clean and blank dwg file, changed the units to architectural and scaled the contours at 12X. There was some sort o white box to the right of your drawing that I couldn't get close to. It would disappear when I zoomed in and would move. I toggled the frames, thinking it may be an inserted image.

Open your surveyor's drawing in AutoCAD. Select a contour line and open the properties dialog box. Depending on the way you are setup, the 2nd section down should be GEOMETRY. About 3/4 down there will be a line named ELEVATION. There, to the right, you will be able to enter the elevation value of the contour line you selected. Do this for each of your contour lines.
Your drawing may have this information entered already. I notice that often when I copy, paste, scale, etc. that the contour lines will lose these values and they need to be entered manually.
Also, you may NOT have the option of ELEVATION, but will see X Y and Z coordinates where the Z coordinate is the value of the elevation. Simply enter your information there.
Someone else may have a simpler method.
