Working with a DEM

Hi. I once had a similar question but this time my data is smaller and much better.

 

I'm hoping to figure out a few things about DEM's.

 

1) vertical exaggeration - what to set it to? Is there data for a Z-scale I'm missing?

2) how to move a DEM as mine isn't located in the right spot.

3) better overall understanding of working with DEMs

 

The DEM data comes from this website: I tried attaching a 10 MB zip but it was too big.

http://www.dggs.alaska.gov/pubs/id/23964

 

When I data connected to the DEM which is in ASCII format it comes in looking okay.

Then I change to 3D mode and it's terrible.

For a while I decided it was my data and I should convert it in ArcGIS... but first I decided to play with vertical exaggeration.

 

Setting vertical exaggeration to .00001 yields this:

Now it's looking good

And I'm satisfied with the way it looks now, but I'm curious why the vertical exaggeration is whack?

 

Also, the section is way off from my other data. How can I move it?

 

Strangely, it seems to work correctly in ArcGIS. Does anyone know any solution I could fix in ArcGIS and then transfer it to AutoCAD? I mainly use AutoCAD.

Additionally, it came with shp files as borders and they're located in the right spot...

 

How do I connect them?

Omg, I think I fixed it. It was allllll because of the coordinates!  Silly me! Sorry for the trouble!
